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.

    So what's w/ all of this switching to turbos?
    I am guessing it is bc turbos weigh less & help mpg?
    Is the difference that much better than a v6 to warrant the change?
    If so, why were turbos not used more than before?

    I have a feeling that this will be short lived.

    Buyers in this class of car, 3 Series, C Class, A4, G35, etc., expect a six and not a four. You can advertise that your four is as good as you 6 was, but Americans count cylinders for status and these cars are purchased more often for status. It would not surprise me if Audi loses sales to brands that offer sixes.

    It is somewhat of a gamble but they need to keep the perfomance numbers up. The best thing they can do is to produce a 4cyl that could outperform the 3 series which is basically its main competitor

    I agree that performance is important. I would hope that Audi will at least equal the performance of the out going engines.

    The other part will be price. If the Audi is priced too close to a BMW with a six, that could be a hard sell.
