Audi said that it will be dropping the 250-hp 3.2L V6 engine from its 2010 model year lineup. Taking its place will be the 2.0L turbocharged 4-cylinder unit used in the 2009 Audi A4, which will also finds its way under the hood of the 2010 A3 and TT models.
So is Audi downsizing its engines? Well, it seems very likely – but weight-saving will play a major part in keeping performance-levels top-notch while increasing fuel-economy.
Audi says that the 2010 S4 and 2010 Audi S5 Cabriolet provide faster acceleration and an increased in fuel-economy by replacing the heavy 4.2L V8 with a lighter 333-hp 3.0 TFSI supercharged V6. It was reported last month that Audi will eventually replace the 3.0L TFSI supercharged V6 in the S4 and S5 with a lighter 4-cylinder turbocharged engine.
With a weight reduction of 3,000 pounds in the next-generation S5, fuel-economy will be increased into the high 20 mpg range. However, according to Audi”s global head of product engineering Michael Dick, the next-generation S5 will lap the Nurburgring a whole 8 seconds faster than the current model.
