Is it a fair comparison to say manuals and auto transmission get the same MPG in newer cars? The 2012 Toyota Corolla has a 132 HP engine and this same engine is paired with either an auto or manual transmission. According to “Consumer’s Reports Guide to New Cars” the MPG ratings are identical, manual or auto. But the 0-60 mph acceleration times are definitely not the same. The manual has a 0-60 time of about 9 seconds, while the auto is 9.9 seconds.
To me, 9.9 seconds is only borderline acceptable for acceleration. 9 seconds makes a car far more drivable, especially accelerating to traffic speed on freeway on-ramps.
While the engines are rated the same HP, the actual power delievered to the wheels is not the same. So is it fair to say the MPG is the same, when the effective power to the wheels takes a big hit with the automatic transmission? I mean if the Corolla manual had a 100 HP engine it could probably hit 0-60 in 10 seconds. And then it would get better MPG.
What do you think?
