The new Audi Q7 is billed as the lightest lightest model in its class, the overhauled Audi Q7 tips the scales at 1,995 kg (4,398 lbs) with the 3.0 TDI engine. It's up to 325 kg (716.5 lbs) lighter than its predecessor. Moving onto engines, we start with the 3.0 TDI rated at 272 HP (200 kW) and 600 Nm (442.5 lb-ft) which is enough for a 0-62 mph (0-100 km/h) run in 6.3 seconds before topping out at 145.4 mph (234 km/h). In this configuration, the Q7 consumes just 5.7 liters / 100 km (41.3 mpg US) and has 149 g/km of CO2 emissions.
A lesser 3.0 TDI with 218 HP (160 kW) and 500 Nm (368.8 lb-ft) will also be available but at a later date.
Audi is offering a 3.0 TFSI with 333 HP (245 kW), 440 Nm (324.5 lb-ft) which does the sprint in 6.1s and reaches 155 mph (250 km/h). This one consumes 7.7 liters / 100 km (30.5 mpg US) and 179 g/km of CO2.
The 2015 Q7 will also get a 2.0 TFSI primarily in Asian markets and United States where it will put out 252 HP (185 kW) and 370 Nm (272.9 lb-ft).
