LaFerrari Hybrid Supercar: 2013 Geneva Motor Show

Tue, 05 Mar 2013 10:19:00 -0600

Ferrari’s LaFerrari Hybrid Supercar made its world debut today at the 2013 Geneva Motor Show.

LaFerrari will be limited to production of only 499 units. No exact price of LaFerrari was announced, but something around $1.31 million (1 million euros) has been widely reported.

Unlike the McLaren P1, which also makes its debut at the Geneva Motor Show in production form, the LaFerrari does not feature a fully electric mode. However, it says the system could be adapted to include an electric-only mode on future cars.

The hybrid technology used, known as HY-KERS, represents the perfect combination of maximum performance and lower emissions. LaFerrari emits just 330 g/km of CO2 but without resorting to electric-only drive which would not fit the mission of this model.

The HY-KERS system is, however, designed so that in future applications a car can be driven using exclusively electric power for a few kilometers and, during development testing, a full-electric version of LaFerrari achieved just 220 g/km of CO2 emissions on the combined cycle.

“We chose to call this model LaFerrari,” declared Ferrari’s President, Luca di Montezemolo, “because it is the maximum expression of what defines our company – excellence. Excellence in terms of technological innovation, performance, visionary styling and the sheer thrill of driving. Aimed at our collectors, this is a truly extraordinary car which encompasses advanced solutions that, in the future, will find their way onto the rest of the range, and it represents the benchmark for the entire automotive industry. LaFerrari is the finest expression of our company’s unique, unparalleled engineering and design know-how, including that acquired in Formula 1."The LaFerrari is equipped with dynamic controls that are integrated for the first time ever on a Ferrari road car with active aerodynamics and the HY-KERS system. Thanks to Ferrari’s proprietary logic which govern all the systems, the car can achieve absolute levels of performance, aerodynamic efficiency and handling without any form of compromise in any area. A very advanced and uncompromising approach was also taken with the interior design which features an HMI inspired by F1 single-seaters.

The LaFerrari is the first car in Ferrari history to be powered by the HY-KERS system. The ICE represents the pinnacle of engine development and research, with a 6262 cc V12 that punches out 800 HP and revs to a maximum of 9,250 rpm, a record for an engine of this displacement. It also features a very high 13.5:1 compression ratio and a high specific output equal to 128 HP per liter. The engine is coupled with a 120 Kw (163 HP) electric motor, giving it a combined power output of 963 HP.

The high torque levels available at low revs from the electric motor allowed the engineers to optimize the internal combustion engine’s performance at higher revs, thus providing a constant supply of exceptional power throughout the rev range. Total torque generated is in excess of 900 Nm.

The hybrid system is composed of two electric motors developed in collaboration with Magneti Marelli – one powering the driven wheels and the second the ancillaries – and a battery pack attached to the floor of the chassis consisting of cells that are assembled in the Scuderia Ferrari department where the KERS for the F138 is also made. The Scuderia’s expertise allowed considerable savings in weight and size of the individual components and the batteries weigh just 60 kg while providing the highest energy density possible for this kind of application.

All in all the car guarantees maximum driving thrills in every situation and performance levels are top level: 0-100 km/h (62 mph) in less than 3 seconds and 0-200 km/h (124 mph) in under 7 seconds, top speed of 370 km/h (230 mph), a lap time at Fiorano of under 1’20” – 5 seconds faster than the Enzo and over 3 seconds faster than the F12berlinetta. LaFerrari is thus the fastest road car in Maranello’s long history.

Ferrari said the LaFerrari gets 16.6 mpg, compared with 15.9 mpg for the F12 and 13.8 mpg for the Lamborghini Aventador.

The batteries are charged in different ways: under braking (even hard braking with the ABS active) and every time the V12 produces more torque than required, such as in cornering. In the latter instance, rather than the being sent to the wheels, the excess torque is converted to energy and stored in the batteries.

The electric motor is coupled with the F1 dual-clutch gearbox to the benefit of optimal weight distribution, but also to boosting energy efficiency as torque is instantly available to the wheels and, vice versa, from the wheels to the electric motor in recharging.

The LaFerrari’s architecture posed the first challenge for the Prancing Horse team at the planning stage of the design. The aim was to achieve ideal weight distribution (59% at the rear) and a compact wheelbase despite the extra bulk of the hybrid system. The result is that all of the masses are situated between the car’s two axles and as close as possible to the floor to lower its centre of gravity (by 35 millimeters) and thereby guarantee dynamic handling and compact dimensions.

The layout of the cabin made a significant contribution in this regard. The seat is fixed and tailored to the driver while both the pedal box and steering wheel are adjustable. The driving position is similar to that of a single-seater and was designed after consultation with the Scuderia Ferrari drivers, Fernando Alonso and Felipe Massa, who played an active role throughout the entire development process.

The LaFerrari’s chassis features no less than four different types of carbon-fiber, all hand-laminated and autoclave-cured in the racing department using the same design and production methods as the Formula 1 car. This helped optimize the design: various functions were integrated (e.g. seats and battery compartment) into the chassis to improve torsional rigidity (+27%) and beam stiffness (+22%) whilst cutting weight.

Active aerodynamics play an essential role, as they allow a complete adjustability of the car’s configuration to attain LaFerrari’s exceptional performance.

The engineers’ aim was to deliver the highest degree of aerodynamic efficiency ever achieved with any road car, with a coefficient of nearly 3, thanks to technical solutions honed with CFD analysis and fine-tuned in the F1 Wind Tunnel.

To boost efficiency, the LaFerrari sports active aerodynamic devices front (diffusers and guide vane on the underbody) and rear (diffusers and rear spoiler) which generate downforce when needed without compromising the car’s overall drag coefficient. These devices deploy automatically on the basis of a number of different performance parameters which are monitored in real time by the car’s dynamic vehicle controls, thus guaranteeing the ideal configuration on the basis of the driving conditions.

One further innovative aspect of the LaFerrari is the integration of its active aerodynamics and hybrid system with the other dynamic control systems aboard. This means the car responds intelligently to driver inputs, making for a seamless blend of unprecedented performance and unparalleled driving emotions.

Proprietary Ferrari algorithms deliver optimal integration of the electric motor and V12 for instantaneous response. In cornering, for instance, the HY-KERS keeps the V12’s revs high to guarantee better acceleration on exit.

The LaFerrari’s Brembo braking system is also integrated with the hybrid system, and incorporates several new features, including new lightweight callipers designed to guarantee correct cooling and carbon-ceramic material (CCM) discs featuring a new composition.

The car’s extreme performance potential called for a different tyre set-up, with 265/30 R 19 Pirelli P-Zeros on the front and 345/30 R 20s on the rear.

McLaren P1 Plug-in Hybrid Supercar

Tue, 26 Feb 2013 08:07:00 -0600

Full details of the McLaren P1 plug-in hybrid supercar have been revealed ahead of its debut at the 2013 Geneva Motor Show next month.

McLaren has been engaging with potential customers actively in the last few months to get their views on the McLaren P1, about the car’s styling. Their unanimous verdict on the styling was not to change the car presented last September in Paris.

So unusually, the McLaren P1 has translated to production form with very little change. In fact just one, the addition of LTR ducts ahead of each of the front wheels to further aid cooling and optimise downforce.

McLaren has closely monitored demand so as to maintain exclusivity, and announced a production number of just 375 units – a figure that will ensure the McLaren P1 will remain a rarity and, if spotted on the road, an unforgettable sight.

McLaren has also announced that the P1 will cost from £866,000 (aboout €1 million or $1.3 million) on the road with a specification that fully equips the car for both road and track use.

The race-inspired Instant Power Assist System (IPAS) gives the McLaren P1 astonishing performance: zero to 100km/h (62mph) will take less than 3 seconds, zero to 200 km/h (124 mph) under 7 seconds, and zero to 300 km/h (186 miles) will be achieved in no more than 17 seconds.

Putting that into perspective, the McLaren P1 is 5 seconds faster than the legendary McLaren F1 road car. Top speed is electronically limited to 350 km/h (217 mph).

The company prides itself on designing performance cars that their owners can use regularly so the McLaren P1 comes comprehensively equipped as standard with an array of colour and trim alternatives from which the customer will be able to choose as well as visible carbon fibre in the cabin. The options list is limited to only bespoke content that a customer might wish to add through McLaren Special Operations, and fitted luggage.

As already announced, the McLaren P1 will have the combined force of two highly-efficient powerplants, offering the optimum mix of superb throttle response, day-to-day drivability and top speed. A mid-mounted 3.8-litre twin-turbo V8 petrol engine is substantially enhanced featuring, for example, larger turbochargers and a highly effective electric motor, to give a combined output of 903 hp and a maximum torque figure of 900Nm. This ensures instantaneous throttle response through the rev range, more akin to a naturally aspirated engine. Emissions of less than 200g/km on the combined cycle are reduced to zero in full electric drive mode, while the Formula 1-derived DRS and IPAS technologies offer an increase in straight-line speed and an instant boost of power.

The tyres fitted to the McLaren P1™ are specially developed P Zero Corsas, which have been developed with McLaren’s technology partner, Pirelli. The team at Pirelli has been involved throughout the entire development program, and this has seen the tyre testing phase integrated into the schedule, as a key performance component. The final compound and construction has been developed and optimized during testing, and the end result is a tyre that is finely tuned specifically to the performance and handling characteristics.

To rein in the power produced by the twin powerplants, the McLaren P1 is designed to offer braking performance more associated with a GT3 or sports racing car. Developed by McLaren’s Formula 1 partner Akebono, the system features a new type of carbon ceramic disc, which has previously seen service in space, but never before used on a road car. Stronger than conventional carbon ceramic, the material dissipates heat more effectively, giving the highly efficient braking system exceptional stopping and cooling capability. The system also boasts significantly reduced weight, and a bespoke ceramic layer coats both friction surfaces to give an attractive mirrored finish.

One surprising feature is that the car can also be driven solely in electric mode. In city driving, with an average speed of 48 km/h (30 mph), this could mean up to a 20km (12 miles) range. More than enough for an owner to enter, for example, a city centre Zero Emissions Zone, have dinner and return home.

Ecotricity Nemesis Electric Sports Car

Sun, 23 Jan 2011 08:42:00 -0600

This is the Nemesis Electric Sports Car designed and built entirely in the UK by the country’s leading green energy company – Ecotricity.

As with the Tesla Roadster, the Nemesis electric sports car has Lotus underpinnings. It is based on the Exige, but is 90mm longer to make room for the electric powertrain and allow more cabin space.

The Nemesis's twin brushless motors can power the electric sports car from 0-100mph in 8.5 seconds, with a top speed of 170mph - faster than a V12 Ferrari.

Uniquely, the Nemesis will be powered entirely by 100% green electricity made by Ecotricity's UK network of 51 windmills. It runs for between 100-150 miles between charges depending on driving style and can be charged from empty in under 2 hours from its fast charger or 8-9 hours from a regular mains supply, both via hidden retractable cable systems built into the rear of the car.

"We wanted to prove electric cars can be quick to develop, beautiful to look at, cheap to run, and run entirely on wind power", said Dale Vince. "I was not looking for something ecological, worthy and a bit self-sacrificial, far from it. I wanted to create something exotic and desirable. Something that would turn heads and challenge stereotypes."The 'Nemesis' development team have between them developed some of the most inspiring sports cars of this century - the McLaren F1, the Lotus Elan, the Corvette 2R1, the Jaguar XJR15 and the De Lorean.

The 'donor' car - a secondhand Lotus Exige - was bought on eBay and rebuilt from the ground up to become the Nemesis. The engineers lengthened the chassis by 90mm, lowered and shifted the centre of gravity forward, fitted a cluster of 96 lithium-ion polymer cells, two brushless motors, a completely new transmission, and a lot of electronic wizardry. Several patents to protect the unique design have already been applied for.

The technology developed for the Nemesis will be incorporated into Ecotricty's next projects, a no-holds-barred 250mph+ wind-powered electric supercar, and an electric tractor to address the next big issue of how we feed ourselves post-oil.

Kepler Motors to Unveil 800hp MOTION Hybrid Supercar in Dubai

Tue, 15 Dec 2009 00:20:00 -0600

Kepler Motors will unveil its MOTION hybrid supercar at the 2009 Dubai International Motor Show, 16-20 December. The Kepler MOTION hybrid supercar uses new modified Ford EcoBoost to drive the rear wheels, while an electric motor drives the fronts, giving the car all-wheel-drive

The MOTION’s Dual Powertrain Technology delivers a combined 800 hp from a 550 hp Ford EcoBoost twin-turbo 3.5 liter V6 driving the rear wheels acting independently of a 250 hp electric motor driving the front wheels.

Kepler claims the MOTION will get to 60 mph in less than 2.5 seconds with a top speed over 200 mph, but it doesn't specify whether that number is based on actual tests or calculations. With this hybrid supercar announcement, there were no claims as to range.

The MOTION uses StopTech’s new Continuous Carbon Ceramic (C3) AeroRotors on all four wheels to ensure smooth, fade-free stopping power. Comprising silicon carbide ceramic material reinforced with long, continuous carbon fibers, the unique C3 brake rotor material offers greater mechanical durability and unique heat transfer capabilities when compared to competitive carbon-ceramic rotors.

To keep the weight down, the MOTION uses a carbon fiber body, along with carbon ceramic brake rotors. Kepler says the two-seat cabin is designed to hold people of above-average size, suggesting the company expects luxury buyers rather than racers.

Kepler said it would only 50 MOTIONs, with production starting in 2011. Each vehicle will be hand assembled.

Kepler Motors is founded by World Speed Record Holder Russ Wicks.

Capstone to Introduce CMT-380 Hybrid Electric Supercar in LA

Mon, 30 Nov 2009 09:59:00 -0600

Capstone Turbine Corp. will introduce the CMT-380 - a high performance hybrid electric supercar powered by traditional batteries and an untraditional ultra low emission range extending microturbine, at the 2009 LA Auto Show next week. The concept for the high performance hybrid electric microturbine vehicle was developed by Electronic Arts Chief Creative Director Richard Hilleman, creator of popular video games, with support from Capstone Turbine, the world's leading clean technology manufacturer of microturbine energy systems.

Capstone and Hilleman's microturbine enabled hybrid supercar features a Capstone C30 (30-kilowatt) microturbine that runs on diesel or biodiesel, which is housed inside a sleek Factory Five Racing GTM body. The Capstone C30 microturbine is so clean it does not require any exhaust after treatment to meet stringent clean air requirements of the California Air Resources Board or EPA 2010.

Capstone Turbine's prototype CMT-380l hybrid-electric supercar combines batteries with
low-emission microturbine technology -- essentially a mini jet engine under the hood.
Performance stats: 0-60 mph in 3.9 seconds, 150 mph top speed, an unheard of 500-mile
driving range on a single tank of fuel and ultra-low exhaust emissions that rival any hybrid.

The CMT-380 features lithium-polymer battery cells that can be charged at home or at a public recharging station. While driving, the sports car can operate on 100 percent battery power in zero emissions mode for a range of up to 80 miles.

When the batteries reach a predetermined state of discharge, the Capstone C30 microturbine quietly fires up and recharges the batteries on the fly to extend the driving range up to 500 miles. The diesel fueled C30 microturbine requires less maintenance than traditional combustion engines and produces ultra-low exhaust emissions.

"The sleek-looking, low to the ground, high-performance supercar definitely raises hybrid's cool factor on several levels," stated Jim Crouse, Capstone's Executive Vice President of Sales and Marketing. "The CMT-380's design performance numbers speak for themselves: 0-60 mph in 3.9 seconds, 150 mph top speed, and an unheard-of driving range of up to 500 miles on a single tank of fuel, all with ultra-low exhaust emissions that rival any hybrid on the market today," added Crouse.

Capstone Turbine is the world's leading producer of clean-and-green, highly efficient and reliable microturbines. Capstone's 30-kilowatt microturbines have been installed in hybrid electric buses, trolleys and transit shuttles around the world, including hybrid buses operating today in U.S. cities like New York, Baltimore and Charlotte, and internationally in London, Tokyo, Paris, Rome and Auckland, reducing greenhouse emissions and extending the range of these state of the art hybrid electric vehicles.

Earlier this year, a C30 liquid-fueled microturbine was successfully integrated into a Ford S-Max people carrier in the United Kingdom by Langford Performance Engineering Ltd.

Capstone has shipped over 5,000 microturbines worldwide which are able to produce energy ranging from 30 kilowatts up to 5 megawatts and are supplying power at sites around the world, including office buildings, hospitals, hotels, universities, oil and gas applications, landfills, waste water treatment plants, farm digesters, industrial manufacturing operations and others.

Capstone microturbines can run on a variety of fuels, including natural gas, waste methane from landfills, biodiesel, diesel, kerosene and propane. Microturbine efficiency increases when used in Combined Heat and Power (CHP) and Combined Cooling Heat and Power (CCHP) applications that utilize waste heat energy produced by the microturbines to recapture and heat water or buildings, or run through an absorption chiller to create air conditioning.

What is a Microturbine?
The CMT-380's 30-kilowatt microturbine features an electric generator and turbine components mounted on a single shaft, which is supported by air bearings -- so there are no liquids to lubricate or cool the microturbine.

It uses a patented combustion system to achieve extremely low exhaust emissions that do not require expensive exhaust after treatment to meet stringent California Air Resources Board and EPA 2010 requirements. Even more efficiency comes from its patented recuperator (or air-to-air heat exchanger), which extracts energy from the exhaust stream and recycles it to preheat air coming into the combustion chamber, thus greatly increasing efficiency. Capstone microturbines are well-known for several reasons:

* Air bearings support the entire rotating assembly. No oil or other lubricants are needed, so maintenance is extremely low and the need to dispose of hazardous materials is eliminated.

* Capstone microturbines operate at extremely high speeds, up to 96,000 rpm, which results in a very high power to weight ratio.

* Microturbines have a smaller footprint and lighter weight compared to traditional combustion engines.

* Continuous combustion and lean premix operation allows for extremely low exhaust emissions.

Bentley Goes Green with Continental Supersports

Wed, 25 Feb 2009 02:29:00 -0600

Bentley has introduced its fastest and most powerful car ever, the muscular Bentley Continental Supersports, and using it as the first step in its plan to make its complete model range capable of running on biofuels by 2012. Available worldwide from autumn 2009, the 630hp Continental Supersports will be FlexFuel compatible in the majority of markets from launch with North American cars offering the capability by summer 2010, following regulatory approval.

The Continental Supersports will be shown next week at the Geneva motor show as a production model which will cost about $250,000.

The Continental Supersports began as an 'under the radar' project exploring the possibilities of weight reduction on the Continental GT but with more power and torque. A largely experimental process crystallized over a period of 24 months into an official new car program, driven by the passion and enthusiasm of a small group of Bentley engineers and designers.

The results are dramatic. With 630PS (621 bhp) and new 'Quickshift' transmission that halves shift times, the Supersports sets new performance benchmarks for Bentley. It accelerates from 0-60 mph in 3.7 seconds (0-100 km/h in 3.9 seconds) onto a top speed of 204 mph (329 km/h).

Supercar performance is complemented by an array of chassis enhancements including retuned steering and suspension, utilizing lighter weight components, retuned dampers and anti-roll bars.

Agility is further sharpened by the 40:60 rear-biased torque split for the all-wheel drive system, a wider rear track, bespoke lightweight 20-inch alloy wheels and a unique electronic stability program.

Carbon ceramic brakes are standard fitment, benefiting steering response, grip and ride comfort, while saving weight. Overall, the engineering team have achieved a weight reduction of 110 kg (243 lb) compared with the Continental GT Speed.

The evolution of the Supersports' design is very much a case of 'form following function' with new purposeful sculptural forms signaling the engineering changes beneath the skin.

For example, the increased power and torque of the W12 engine necessitated additional airflow to the twin turbocharger intercoolers and cooling system. Bentley's designers responded with a purposeful and dramatic style that features large vertical intake apertures and twin bonnet vents.

Similarly, new flared rear wings that accommodate the 50 mm (2 inches) wider rear track are designed to emphasize the powerful stance of this ultra-high performance coupe. The resultant Supersports style combines the looks of the iconic Continental GT with a new and distinctive appearance that reflects its more extreme character.

The Supersports is further distinguished from its Continental coupe stable mates by a unique dark-smoked steel finish to all exterior 'brightware', including front grilles, lamp bezels, window surrounds and wheels. A complex 'Physical Vapour Deposition' process is applied to all stainless steel components to give a lustrous and highly durable finish. A car industry first, this process is normally used as a coating on industrial tools, watches and even hip replacement joints.

Fully embracing the extreme spirit of the Supersports, Bentley's interior designers have created a unique ambience. The cockpit represents a dramatic re-interpretation of Bentley interior design in which carbon fibre and AlcantaraTM not only convey a sporting and contemporary style but also reduce weight.

The Supersports is a strict two-seater featuring all-new lightweight sports seats with carbon fiber clamshell rear panels. In the rear compartment, the seats are replaced by a stowage deck with a carbon fiber luggage retaining beam.

The new interior also provides a showcase for the skills of Bentley's craftsmen and women at the company's factory in Crewe, England. Signature premium grade leather and brightware are complemented by carbon fiber panels, replacing traditional wood veneers.

The Continental Supersports is capable of running on either petrol and E85 biofuel or any combination of the two. E85 biofuel can offer a reduction of up to 70 per cent in CO2 emissions on a 'well-to-wheel' basis.

The fuel supply system detects the blending ratio of the fuel in the tank and ensures that power and torque remain constant regardless of the ratio of petrol to biofuel. The result is seamless power delivery in the Bentley tradition.

The 'Supersports' name is inspired by the original two-seater 3-liter Supersports model introduced in 1925, itself an evolution of the 3-liter Speed. The lightweight, 85 bhp Supersports was the first production Bentley to reach 100 mph and was also renowned for the application of Le Mans-winning race technology.

P1-E - New Electric Sportscar from UK

Fri, 23 Jan 2009 07:17:00 -0600

Former McLaren designer Jim Dowle (JJAD) has revealed details of his eye-catching P1-E electric sportscar. With stunning acceleration (0-60mph in 2.9 secs), practical range (230 miles), low weight (1,055kg) and a price around £55,000 ($74,600), this gullwing–doored, pocket rocket will be the electric car enthusiasts really will want to own.

Having worked on such landmark projects as the McLaren F1, Dowle knows what it takes to make a drivers’ car.

The P1-E’s twin electric motors and attendant lithium-ion batteries are placed for optimum weight distribution and low centre of gravity, while the long wishbones front and rear ensure ideal suspension geometry.

The P1-E will use a four-wheel-drive system to harness the 590lb ft of torque developed by the electric motors at either end of the chassis, with combined output for the twin motors expected to be 290kW (389bhp).

Four-wheel drive endows the car with maximum traction. It also allows regenerative braking on each wheel, the energy gained from which is used to top up the batteries.

Said Dowle, “All the electric cars produced to date have been compromised in one way or another and most have been of little attraction to the enthusiast driver. We decided it was time to create an affordable electric sports car that combined the advantages of conventionally-engined machines with those of electric ones, without the disadvantages of either – in short, a drivers’ car for the 21st century.

“Since February we’ve been busy finalizing the specification, fine-tuning the styling and seeking appropriate funding, and plan to have our first prototype up and running during 2009. Most of the program’s key partnerships are now in place, though we’d still welcome approaches from any companies interested in investing in our mould-breaking performance car. Another remaining task is to agree its final name, P1-E being the project’s code.”
