Porsche has plans to upgrade the V8 3.4 liter with direct injection that is used in the current Porsche RS Spyder and the ALMS LMP2. This engine technology was first created for the Porsche 911 and Cayenne.
The technology was developed for the Porsche Cayenne and Porsche 911, and, given the performance advantages, engineers decided to back-hack it into the prototype V8. The old version of the engine turned out a stout 476 HP at 10,000 RPM along with 273 lb-ft at 7,500 rpm; the direct injection and obviously remapped fuel curve bump power to 503 HP at 10,000 RPM, and 284 lb-ft of torque at 8,500 rpm. This motor communes with hummingbirds.
According to Porsche, the most notable advantage â€” after the power upgrades â€” is the improved energy efficiency. With lower fuel consumption, the engine not only makes the car go faster, it keeps it out of the pits, a key to any race, endurance or otherwise. Also interesting is that Porsche seems to have aped GM’s “No Lift Shift” present in the Chevy Cobalt SS for the new car, with the option of full-throttle shifts.
