After teasing a production concept of a new Q60 sports coupe at last year's Detroit Auto Show, Infiniti has come forward with the production version at this year's show. The new Q60 features a new look, an all-new V6 engine, and a global design.

As promised with last year's unveil, the newly redesigned Infiniti Q60 is lower and wider than previous generations. This follows Infiniti's promise of more performance for the sleek coupe. General design language of the Q60 remains similar to the Infiniti line, following the strong lines of the Q50 sedan.

The new Q60's front fascia is dominated by a wide grille flanked by thin, peering headlamps, below which a trapezoidal intake opens. Tight wheel wells inside which large wheels (19-inch standard, 20-inch available in some markets) and thin-profile tires promise performance and precision handling. Hood lines are simple bulges between which the rounded hood flows. Those bulges accentuate the front fenders, whose definition line flows along the doors to the wide rear fenders. The coupe's roofline is fastback to the rear.

Hints from the old Q60 can be seen in this new design, with the accented brake cooling vents behind the front fender, the curving rear window glass swoop, and the high beltline. The new look is proportional and fast paced. It's also functional, providing excellent aerodynamics with a drag coefficient of 0.28.

Two engines will be offered with the new Infiniti Q60 – a turbocharged 2.0-liter four-cylinder and an all-new 3.0-liter V6. The four-cylinder produces 208 horsepower (155 kW) and 258 pound-feet (350 Nm) of torque. Maximum torque comes at only 1,500 rpm thanks to those turbos and a high-pressure direct injection system. Fuel efficiency for the four-cylinder is expected to be 24 mpg (9.8 l/100km) highway.

The all-new twin-turbocharged V6 delivers a phenomenal 400 horsepower (298 kW) and 350 lb-ft (475 Nm) of torque. That max torque is delivered in a broad band between 1,600 and 5,200 rpm. This engine is expected to deliver 22 mpg on the highway, Infiniti says. A less powerful version, offering 300 hp (224 kW) and 295 lb-ft (400 Nm) is also being offered and will offer 23 mpg highway.

These engines run through a seven-speed automatic transmission with Adaptive Shift control for a responsive gear selection in various conditions. This transmission powers the Q60's rear wheels in standard models and all four wheels in all-wheel drive models.

Also featured on the new Infiniti Q60 coupe will be the second-generation of the company's Direct Adaptive Steering, available with the twin-turbo V6 models. This has seen some re-tuning to improve steering feel and to allow driver customization for personal preferences. The new DAS system is capable of making 1,000 steering adjustments per second without a mechanical link between the wheel and the all-new Infiniti Rack Electronic Power Steering system. This is an electric-assisted power steering system designed to work with the DAS steer-by-wire system. All other versions of the Q60 will utilize the hydraulic-electronic power steering system found in the standard Q50 sedan models.

Also shared with the Q50 is the suspension system in the new Q60. The standard suspension set balances road noise, highway glide, and sport feel. Some changes, such as bushing sizes and shock absorber layout, have been made to fit the Q60's smaller size. In the sportier twin-turbo model, however, an all-new Dynamic Digital Suspension system is standard. This offers software and hardware upgrades from the previous DDS with adjustable dampers and electronically-adjustable shock absorbers. Driver-selected modes adjust the suspension to match conditions and driver's requirements.

All Infiniti Q60 coupes have Active Noise Cancellation as standard, preventing negative engine noise frequencies from entering the cabin. Accoustic glass is also standard in the Q60. A new world-first 13-speaker Bose Performance Series sound system will also be included, working in conjunction with the noise-cancelling system.

The interior of the Q60 is dominated by large, heavily-bolstered bucket seats. These are "spinal support" seats, similar to Infinit parent company Nissan's "Zero Gravity" seating. Also standard in the new Q60 is the latest generation of Infiniti's InTuition infotainment system. A faster processor means faster responses, Infiniti promises, with control over climate, seating position, audio, navigation, and more.

The Infiniti Q60 coupe will enter selected markets globally later this year.
