Like It Or Not, More CVTs Coming From Automakers

Automakers are in the midst of a love affair with the continuously variable transmission (CVT). The gear-eliminating transmissions boost fuel economy, improve performance and are less complex (and hence less expensive), allowing automakers to achieve CAFE regulations and pad the bottom line at the same time.

To the enthusiast driver, however, nothing has contributed to the decline of the modern automobile quite as much as the CVT. The gear-less transmissions produce more sound than fury, and feel to many of us exactly the same way that a failing automatic transmission feels. Do we need to mention that that’s not a good association to have?

Love them or hate them, CVTs are hear to stay for the exact reasons mentioned above. As Automotive News (subscription required) points out, CVTs are expected to grow in usage from seven percent of the market in 2010 to 16 percent of the market in 2015, thanks in part to general acceptance by consumers.

Nissan has been a strong proponent of CVTs, and it now uses them on all front-wheel-drive vehicles. Still, the automaker had concerns about the technology in the early days, and Nissan America’s senior vice president of R&D, Carla Bailo, admitted, “We debated a long time about whether customers would be satisfied with the feel of a CVT.”

The net result? As Bailo puts it, “Most of them (new car shoppers) don’t notice it so much.”

Even Honda is embracing CVTs on new models, like the upcoming redesigned Accord. Said American Honda spokesman Chris Martin, “Nobody’s coming into our dealerships asking for CVTs. But they are coming in and asking for fuel economy... a CVT provides the fuel efficiency we want in both highway and city driving.”

Not every automaker feels the same, however. GM has abandoned CVTs after a disastrous experience with CVT failures in Saturn Vue and Ion models. GM later agreed to a class-action lawsuit settlement over CVT failures, but payments to plaintiffs were blocked by GM’s 2008 bankruptcy.

Ford attempted to use CVTs in its Freestyle, Five Hundred and Mercury Montego models, but the reviews were bleak (in fact the Freestyle’s transmission still sticks in our mind as the worst CVT we’ve ever driven). Ford’s powertrain spokesman, Richard Truett, summed up the automaker’s position by saying, “CVTs are not the way forward for Ford.”

While modern CVTs have gotten more reliable and more user-friendly (including some that simulate “gears” and allow drivers to manually shift), they’re still loathed by those with a passion for driving. As long as the bulk of consumers don’t care what translates torque into forward motion, CVTs will only continue to climb in popularity.

  1. Thank you for a good article! I agree that CVT's are the future of transmissions. Fuel consumption apart, they may not need a clutch, like the manual and automatic counterparts do; they also allow infinite gears while keeping constant engine's angular momentum, which make easier operating vehicles at peak engine power rate. This is also convenient to couple your gas motor to an electric power train. My wife and I drove recently from Miami to San Diego, CA in a 2012 Prius 5 (1.8L) via I-10, and then I-8. We (two big people and significant luggage) averaged 46.5 mpg, and the CVT worked flawlessly. I could sense lack of power a bit going up long hills, but switching from hybrid mode to power (gas engine) mode minimized the issue.

  2. @Adalberto, I agree that CVTs make sense for hybrids, but too many automakers are rolling them out on mainstream vehicles, some with mild performance aspirations. The new Nissan Altima, for example, comes only with a CVT in all trims. I'll admit it's the least-worst CVT I've driven, but it still detracts from an otherwise superb car.

    To paraphrase Kurt Vonnegut, taking an anti-CVT stance is the same as taking an anti-glacier stance. Nothing will stop their steady progress...

  3. There is a world of difference between belt-and-pulley CVT that Nissan and Honda use and Toyota/Aisin drive. A belt-and-pulley CVT won't make coupling motors any easier (or more difficult) than a conventional automatic, while the Aisin plantetary-and-3 motors design works only as a hybrid. Also, unlike the belt-and-pulley CVT, the Aisin design has no special lube requirements - which are the root cause of many CVT reliabiliy problems. While both keep the ICE operating at optimum RPM for the power demanded, and both contribute to the disconnect between engine note and road speed, there is very little in common between the two in powewr paths or sourcing.
