This is where the Continuously Variable Transmission (CVT) in the Nissan Juke has come under fire. CVTs aim to boost fuel economy and deliver a seamless power delivery—with detractors saying they cost the thrill of driving with an automatic or manual. One of the main criticisms of the Juke's CVT has been its 'rubber band' effect – the revs of the engine don't always correlate with the vehicle's acceleration in a way which is natural to many drivers. There also has been reliability concerns with Nissan CVTs in general. But some drivers besotted with the smoothness and efficiency of the CVT, especially in city driving conditions, are not so enthusiastic. The question, therefore, is whether efficiency and driving enjoyment can be reconciled, and whether CVT's benefits are worth its drawbacks in a car that strikes a marketing partnership with notions of sport.
