Audi Q7 Gets More Efficient TDI Engine

Font size: Decrease font Enlarge font

Audi has added a new and especially efficient member to its Q7 family.

The Audi Q7 3.0 TDI offers 150 kW (204 hp) while consuming an average of just 7.2 liters of diesel per 100 km (32.67 miles per U.S. gallon) – better than all direct competitors.

The new V6 TDI in the Audi Q7 is a high-tech engine. It weighs far less than 200 kilograms (440.92 lb) and extensive measures minimize internal friction. Innovative thermal management – a new feature of many Audi engines – is particularly complex in the 3.0 TDI. The crankcase and the cylinder heads have separate cooling water circuits; coolant is not circulated within the block while the engine is warming up.

A common-rail system with lightning-fast piezo injectors provides injection pressure up to 2,000 bar; the turbocharger and the camshafts' control times have been optimized for maximum efficiency. A start-stop system deactivates the engine as soon as the vehicle comes to a stop, and an energy recovery system – standard for the entire model line – stores energy during deceleration.

The EU 5 classification for this new entry model in the Audi Q7 family will come as no surprise, just like its high fuel efficiency. On average, it needs 7.2 liters per 100 km (32.67 miles per U.S. gallon). And its CO2 equivalent is just 189 grams per km (304.17 grams per mile) – no other large SUV from a European brand boasts such a low value. The efficient TDI delivers 150 kW (204 hp). Its maximum torque becomes available just above the idling point: 450 Nm (331.90 lb-ft) remain constant between 1,250 and 2,750 rpm.

This large SUV accelerates from 0 to 100 km/h (62.14 mph) in 9.1 seconds. In the version with an optional air suspension, it reaches a top speed of 205 km/h (127.38 mph); with steel suspension, 202 km/h (125.52 mph).

The Q7 3.0 TDI with 150 kW (204 hp) offers the same power transmission as all other models in this line. The new and efficient eight-speed tiptronic – with its high overall gear ratio – delivers torque to the quattro permanent all-wheel drive, which has a sporty rear-end bias. Double wishbones made of aluminum guide all four wheels; the chassis delivers great agility and stability. An off-road mode and a hill-descent assistant aid off-road driving.

With a wheelbase measuring 3.00 meters (9.84 feet) and an overall length of 5.09 meters (16.70 feet), the interior offers plenty of room. Audi offers the Q7 with five, six or seven seats. The luggage compartment offers as much as 2,035 liters of capacity (71.87 cubic ft). This new entry model's standard equipment package includes two-zone deluxe automatic air conditioning, a high-beam assistant, and an MMI radio multimedia interface.

Options include climate-controlled comfort seats, a panoramic glass sunroof, an electric tailgate, and a load-securing kit with rails for cargo. Sophisticated driver-assistance systems and a system of ultramodern infotainment modules round out the offer.

Despite a generous equipment package, this model line's new entry model costs just 51,800 euros in Germany. This basic price makes the Q7 more affordable than all of its direct competitors.
