Volkswagen redesigned its Beetle hatchback for the 2012 model year. Sporting more retro cues than its predecessor, the Beetle can have either of two gas engines or a diesel, the latter of which gets up to an estimated 41 mpg on the highway. Competitors include retro hatchbacks like the Mini Cooper and Fiat 500.

2013 BMW 6 Series 650xi Convertible

2013 BMW 6 Series 650xi ConvertibleThe 650i is the only 6 Series trim available for 2012; the convertible is hitting the market ahead of the hardtop coupe. The rear wheels are powered by a 400-horsepower, twin-turbo 4.4-liter V-8 engine. It comes with either a six-speed manual or eight-speed automatic transmission at no additional charge … sort of. The manual gets 15/22 mpg, and with that comes a $1,000 gas-guzzler tax.

My test 650i came with the eight-speed automatic, good for 16/24 mpg city/highway. Performance fans won’t mind the eight-speed: It shifts quickly and smoothly, and steering-wheel-mounted shift paddles allow for manual shifting.
