Audi Dropping New 1.4-liter TFSI Four-Banger In A3, A3 Sportback

The 2.0 TFSI engine from the knights of Bruce has already taken some serious metal in the "Best of" categories. Now Audi's using that technology to create a smaller version of the award-winning 2.0-liter engine, announcing a new, "ultra-modern" (we're pretty sure that's code for über-Bruce) 1.4-liter four-cylinder Turbo Fuel Stratified Injection (TFSI) engine. It's ready to be dropped right into the engine bay of the Audi A3 and A3 Sportback. With 125 HP at 5,000 RPM and a maximum torque of 148 lb-ft. The first A3's to get the new engine hit the streets in September of 2007. Full press release after the jump. (Hat tip to Turboner!) [via AudiWorld]

Efficiency and Performance: New 1.4 TFSI Engine in the Audi A3

A new, ultra-modern four-cylinder TFSI engine with a displacement of 1.4 litres and turbocharger can now be ordered for the Audi A3 and A3 Sportback. The 1.4 TFSI engine delivers 92 kW (125 bhp) at 5,000 rpm. Its maximum torque of 200 Nm is available across an unusually wide speed range of 1,500 to 4,000 rpm.

Audi's engineers have long been demonstrating the effectiveness of FSI technology in combination with turbocharging both on the world's racetracks and on the road. The prime example of this is the "Engine of the Year" award with which a jury of experts crowned the 2.0 TFSI in 2007 for the third time in succession.

This concept is being consistently used once again for the new 1.4 TFSI in order to combine optimal levels of efficiency and performance. Six-hole injectors guarantee highly homogeneous mixture preparation and extremely efficient combustion. The reduction of pollutants is also aided effectively in this way.

The integrated turbocharger and modified exhaust valve timing ensure optimised responsiveness and help torque to build up even more smoothly. 80 percent of the maximum torque of 200 Nm is available from 1,250 rpm, just above idle speed. The 1.4 TFSI at the same time sets new standards in its class in terms of acoustics. The new high-tech unit from Audi can be ordered for the A3 and A3 Sportback in combination with a six-speed manual gearbox.

With a top speed of 203 km/h and acceleration from a standstill to 100 km/h in 9.6 seconds for the three-door A3, the 1.4 TFSI ensures supreme performance. Its average fuel consumption is just 6.5 litres of premium-grade fuel per 100 km.

The basic price of the A3 1.4 TFSI Attraction is 21,350 euros. The first vehicles will be available in September 2007.
