The manual may therefore seem like a more attractive choice, but we discovered that after only 12 minutes of hard driving, it simply couldn't handle the immense amount of power being fed through it. (It's carried over from the 394-hp V8 in the previous M5.) It began to overheat, causing the car's computer to lower the engine's redline to 6,000 rpm. The SMG is still not as smooth as we'd like, but we'd probably recommend it over the manual transmission.
