The 2013 Honda Accord has both 4 cylinder and 6 cylinder cars, however, only the 4 cylinder cars have a continuously variable transmission (CVT). I was wondering... is there any particular reason for this?

There's no fundamental reason you can't have a CVT with a 6-cylinder engine. The simplest explanations I can think of are:

  1. The market for CVT is people who want modern efficient vehicles, the opposite demographic of people who want 6- and 8-cylinder engines, and

  2. The CVT helps deliver the right amount of torque at a wide range of speeds, reducing the need for an over-powered engine.

I also suspect that a CVT isn't strong enough to handle 200+ BHP/140+ kW. – Juann Strauss Sep 25 '13 at 9:21
I hadn't thought of that but I suppose it's also a possibility. – R.. Sep 28 '13 at 23:27

I'm willing to bet that's it. It's probably a long-term reliability thing. All these new CVTs have yet to prove themselves with lots of power. Otherwise racers would be all over it (sanctioning body rules excepted). – Nick Oct 7 '13 at 18:49
