Audi's added three more FSI petrol engines, known for their efficiency, to its A3, A6 and Q7 models this week.
A3 and A3 Sportback models, which already use FSI direct petrol injection in their 1.6-litre, 2.0-litre and 2.0-litre Turbo engines, are now available with a new 1.8-litre Turbo FSI unit with 158bhp and 184lb-ft of torque. The second Audi unit to combine turbocharging and FSI injection takes the three-door A3 1.8 TFSI to 62mph in 8.0 seconds and on to a top speed of 136mph, while also returning up to 38.6mpg with a C02 output of 174g/km.
The 3.2-litre V6, 4.2-litre V8 and 5.2-litre V10 FSI engines powering the A6 Saloon and Avant ranges have been joined by a new 2.8-litre V6 FSI with 207bhp and 206lb-ft of torque.
This mill's got special valvelift system that Audi claimed reduces fuel consumption by around ten per cent by controlling valve movement more precisely than conventional systems. It means the A6 2.8 FSI can cover 0-62mph in 7.9 seconds and reach a top speed of 151mph, yet returns 32.4mpg (combined) with a C02 output of 207g/km.
The third new engine is destined for the Q7, and slots between the 3.0 TDI V6 and 4.2-litre V8 FSI models. The new six-pot Q7 3.6 FSI delivers 276bhp and 265lb-ft, and powers to 62mph in 8.5 seconds on the way to a 142mph maximum speed. Its combined consumption figure is 22.2mpg, with C02 output of 304g/km.
Audi's now got FSI technology in most of its petrol-powered products. According to the company, this means that lower emissions, and improved economy and performance are achieved by the injection of fuel directly into the cylinders (not as fuel vapour via the conventional inlet manifold) via a high-pressure common rail injection system supplied by a single-piston injection pump.
