The Infiniti Q50 is one of Nissan's better models. It's a sports sedan that's enjoyable to drive and comes close to the spirit of the established German competitors. Viewed against its peers, the Q50 offers V6 power for the price of competitors' four cylinder engines. As such, the Infiniti has an edge in outright acceleration but sacrifices fuel economy. Moreover, the Q50 isn't as polished when it comes to noise isolation, ride comfort, interior appointments and infotainment systems.
The 3.0t model, with all-wheel-drive puts it right in the hunt with an Audi A4, BMW 330i and Mercedes-Benz C300. That German trio, however, has more comfortable seats and nicer trimmed cabins. Plus, the infotainment systems in the Audi and BMW are much better.
The Q50's punchy, 300-hp V6 turbo gives it oodles of reserve power, making it satisfying to drive. It also shoots from 0-60 mph in a commendable 5.7 seconds -- about half a second quicker than its rivals. Of course, there's a price to pay for this. At 22 mpg overall, the Q50 isn't nearly as frugal as an Audi, BMW or Mercedes competitor which register 26 to 29 mpg in our testing.
