It’s seems a pretty unfair contest, nonetheless, the guys from Autocar wanted to demonstrate how well the big 911 Turbo performed in terms of being clean. To make the contest more unfair/fair, the Peugeot will tour the track near it’s maximum threshold whilst the trailing 911 will only be driven hard enough to keep up with the Pug.

Interestingly, the 911 Turbo is, according to the report, one of the most fuel efficient and environmentally friendly supercars available. It also offers a great power-to-CO2 emission ratio, emitting 272 grams of CO2 per kilometre.

Since the Turbo produces 368kW of power, it actually produces less CO2 per kilowatt than a 2010 Holden Commodore Omega 3.0-litre SIDI V6 engine. The 3.0-litre V6 offers 190kW of power and emits 221gm of CO2/km, equaling 1.16gm of CO2 per kilowatt. The Porsche? 0.73gm of CO2 per kilowatt.

Anyway, we don’t want to spoil the the results too much. What will say though is it ends up being pretty close. Take a look.

He says the insipiration behind the test is Porsche’s claim of the 911 being the most eco friendly supercar, he should man up however and admit that the REAL inspiration behind the test was an IDENTICAL test Top Gear did between a BMW M3 and a Toyota Prius in which the M3 won.

hah I was just going to say this is a Top Gear rip off. How pointless is this test?

Baddass

I love Autocar but this test seems pointless.

This is 100% pointless. Some how it’s actually really irritated me. A relaxed pace versus someone driving all out is just so stupid!

The test is trying to prove the efficiency of a larger torque laden engine compared to a smaller engine when a certain rate of acceleration is consistently required. This can be replicated with most models of cars if they are of similar mass- (M3 vs Prius, 4.0 Falcon VS 3.0 Commodore) but Porsche is trying to re-invent the wheel here!
