Infiniti just officially announced the new Q60 sports coupe here at the Detroit Auto Show, a redesigned 400-horsepower follow to the previous model (and the Q50 sedan released a few years ago). The car's existence wasn't necessarily a surprise — it first showed up as a concept car one year ago to the day, and leaks of the production version have been around for months. Nissan CEO Carlos Ghosn said that the Q60 is a near-translation of the concept, but there is some new stuff going on inside.

The Q60 comes standard with all-new high performance 3.0-liter twin-turbo engine, the most powerful version of which outputs 400 horsepower. That's a noticeable difference from the Q50 sedan's standard 3.7-liter engine, which only put out 328 horsepower (360 on the hybrid version). The car, which runs in the similar luxury circles as cars like the Mercedes C-Class, has a 7-speed transmission and will also have the option for all-wheel drive. Three options for the new engine The one big surprise is that there will also be an option for a smaller, 2.0-liter, single-turbo engine, too. That engine is a 4-cylinder, though, and will give drivers 208 horsepower to work with. Those same engine options will be available on the new 2017 Q50 as well, giving it a bump up in performance. It's the first big engine change for this section of Infiniti's lineup in years.

The design of the 2017 Q60 is also all-new. It's a much less aggressive look for Infiniti. The body smoothly curves back to a more rounded rear end than we're used to, but Infiniti did keep the company's signature angular front grille, which is adorned with bright LED headlights. The interior gets an upgrade, too, with options like red or white leather, silver glass fiber accents, and aluminum or wood trim. The new model also comes with some future-facing features, like lane assist, forward emergency braking, and backup collision warnings. Infiniti needed this new look and feel to compete in the market going forward; companies like Mercedes and BMW have been pushing hard in this category lately, and things won't get any easier when the M2 is shown off later this week.
