ALL AUTOCARS

Recently, 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.

The 3.4-liter V8 in the Porsche RS Spyder campaigning in the ALMS LMP2 class will be fitted with direct injection, bringing power levels up while reducing fuel consumption. The old engine is capable to produce 476 hp at 10,000 RPM and 273 lb.-ft. of torque beginning at 7,500 RPM. However, the new engine gets a 27 hp bump, to bring levels up to 503 hp at 10k RPM and 284 lb.-ft. of twist at 8,500 rpm. That, combined with the decreased in fuel consumption should make the Spyder even more competitive in a class it's continuing to dominate.
