The new electric Audi R8 will be released towards the end of this year, and it looks amazing! I'd also rate the new Tesla S one of the best vehicles this year because of the companies outstanding track record in the stock market this year.
I would say overall, the Chrysler 300/ Charger if I had to pick one. It'll give you a full-size sedan with 292HP V6, RWD, and an 8-spd trans, while delivering 31 mpg hwy back. That's a pretty nice package. Not to mention the fact that there are also much more powerful V8s available (470hp), incredible quality and style, TONS of available features (heated/cooled cup holders and seats, adaptive cruise, blind spot, heated steering wheel, power everything, AWD, and arguably the very best infotainment system in the industry), the fact that your supporting an American car company. The entire car as a package is really well thought out.
