Porsche has already introduced direct injection on the Cayenne and 911 Carrera, and the Turbo, GT2 and GT3 all stand to benefit from the technology next year. While it's normal for most automakers to take the lessons learned from motorsports and apply them to their road cars, Porsche is doing it the other way around.

Porsche's commitment to the KISS philosophy of exterior design won't extend to the engine of the facelifted 911 Turbo, GT2 and GT3 when they're released early next year. All three models will dispatch with the legendary M97 powerplant in favor of the new, direct-injected A91 flat-six that's equipped on the recently updated 911 Carrera.

High fuel prices have car buyers looking away from V8 engines in favor of smaller, more efficient powertrains. GM is looking to feed the increased demand with an expansion of its Ramos, Mexico plant that builds its 3.6L V6 engines. The planned increase in output will allow the General to increase production of its next generation V6 engines an additional 350,000 units to a whopping 940,000 engines per year. The next generation HFV6 engines will also provide more of everything customers want, including improved fuel economy and a 6% increase in power. The engines will likely feature direct injection across the lineup this time.

While we like to chide the Stuttgart crew for "updates" to its 911 range, this newest one actually has some serious substance underneath the tweaked sheet metal. In addition to the revised headlamp and taillight design, CAR is reporting that Porsche will upgrade both the 3.6- and 3.8-liter flat-six boxers with direct-injection. The technology, first employed by Porsche on the 2007 Cayenne, boosted horsepower and torque by around 10- to 15-percent in the SUV, and we hope that similar gains can be made with its iconic six. More impressive, although not entirely unexpected, is the rumored fitment of Porsche's first dual-clutch gearbox.
