Audi just announced the new engine powering the Audi S6 and S7, and a variant of the engine will power the S8. This is a twin-scroll, twin turbo low-displacement V8 with direct injection, cylinder deactivation, variable timing and active engine mounts. As all manufacturers pursue better fuel efficiency but higher power outputs from their engines, these technologies will be seen in many cars very soon. Full details are available at Fourtitude.

Last year I published a list of cars with direct injection, looks like Winding Road beat me to it and published a an updated list. I love direct injection engines because it’s one of those technologies that defy the fuel economy/horsepower tradeoff. Direct injection engines have better fuel economy and higher performance.

Their complete list is on their website and it’s amazing how large this list is. Just a few years ago, only Audi produced cars with this technology, now almost every brand is represented.
