Audi Q5 – engine details

Audi is maintaining its successful efficiency strategy: the new Audi Q5, the sports car in the SUV category, is its latest model to combine high performance with low consumption. This progress is underpinned by an extensive package of hi-tech solutions ranging from energy recuperation to engine downsizing.

Audi is bringing the new Q5 onto the market equipped with three powerful, sporty engines – one turbo FSI gasoline version and two TDIs, all of which are state-of-the-art units featuring turbocharging and direct fuel injection. The perfect interplay of these two technologies paves the way for downsizing, which involves using supercharging as a means of trimming engine capacity. This enables the Q5 to achieve CO2 emissions of less than 200 grams per kilometer (321.87 g/mile).

The new 2.0 TFSI, the successor to the engine that was voted “Engine of the Year” four times in a row, is an object lesson in efficiency. The performance of this four-cylinder engine, which develops 155 kW (211 hp) and 350 Nm (258.15 lb-ft) of torque, puts it in the same league as conventional six-cylinder engines. Yet its fuel consumption averages only 8.5 liters per 100 kilometers (27.67 US mpg) – giving it a clear advantage over its competitors.

The TDI engines fit in with Audi’s downsizing strategy. The four-cylinder diesel develops an impressive 125 kW (170 hp) from its two-liter engine. It delivers 350 Nm (258.15 lb-ft)
of torque and covers 100 kilometers on an average of just 6.7 liters of fuel (35.11 US mpg) in the Audi Q5. The top diesel in the Q5 is the 3.0 TDI, a V6 with an output of 176 kW (240 hp) and a massive 500 Nm (368.78 lb-ft) of torque. Its average consumption over 100 kilometers is just 7.5 liters (31.36 US mpg).

The high torque values at low revs have allowed the engineers to select slightly higher transmission ratios without undermining dynamic performance. The peak torque is achieved at a very early point on all engines in the Audi Q5 – the 2.0 TFSI, for instance, already achieves its 350 Nm (258.15 lb-ft) at 1,500 rpm, barely above idle speed. The Q5 thus handles supremely well at low revs – with correspondingly good fuel efficiency.
