2017 Infiniti Q60 Coupe debuts with 400-hp V6

Infiniti killed it with the G35 Coupe in 2002, its second act being the G37 in 2008. The third act has officially begun, the 2017 Q60 Coupe launches today at the 2016 Detroit Auto Show. It hasn't strayed far from the concept shown a year ago, the major tweaks being government-approved headlights and side mirrors. Without discussing numbers, Infiniti says the new car is lower and wider than the current Q60, with a lower center of gravity, and it is more powerful and efficient. Much has gone on with the rolling stock, too: tighter wheel gaps, staggered tires on some models, wheels designed to absorb road vibration, and optional 20-inch alloys available for the first time. In the US, there are two engine choices with three levels of output. The twin-turbo 3.0-liter V6 comes with either 400 horsepower and 350 pound-feet of torque, or 300 hp and 295 lb-ft. In the US that will mean a boost of 70 hp and 80 lb-ft over the 3.7-liter V6 in the current car, and Infiniti estimates a combined fuel economy rating of 22 mpg. The 300-hp unit has a provisional rating of 23 mpg, the increased efficiency down to bodywork shaping and an active shutter behind the grille. A direct-injected, 2.0-liter, four-cylinder turbo is the second engine, getting 208 hp and 258 lb-ft and an estimated 24 mpg in the US. All engines will shift through an adaptive seven-speed automatic transmission. G'bye, manual gearbox. A Drive Mode Selector can dial through six settings, the Customize option throwing up three more individual choices to get the most from the updated internals. The V6 models can be optioned with Infiniti's second-generation Direct Adaptive Steering and brand-new Rack Electronic Power Steering that claims to provide more linear assistance. The four-cylinder comes with a speed-sensitive rack-and-pinion setup. Revisions to the base suspension include relocated shock absorbers among a new link layout, and modified shock tuning and bushings. Above that there's a brand new Digital Dynamic Suspension that will come standard on the Sport trim, now with adaptive dampers. Both units should have improved performance thanks to stiffer crossmembers. Finally, the cockpit gets dressed in one of three trims depending on the model, with aluminum or black wood at the entry-level end, carbon fiber at the other end, and silver glass fiber for buyers who choose the white or red leather.

Infiniti Pebble Beach retro concept is a '50s-inspired electric grand prix car

Infiniti will debut a retro-inspired race car at next week's Pebble Beach Concours d'Elegance that combines the style of classic grand prix open-wheel cars with modern design elements and powertrains. The car should fit right in at Pebble Beach alongside all the vintage machinery from the early days of motorsports. Simply dubbed the Infiniti retro prototype, it is Infiniti's idea of what could have been. Basically, the Japanese automaker imagined that it found a car hidden away for 70 years in southern Japan. They took that old look and married it with the brand's "Powerful Elegance" design language. We only have a couple of photos, but it looks like a sleek silver bullet with narrow-section bias-ply tires. We'll have to wait until next week to see the entire thing, but this teaser has us excited. As expected with any modern concept, the retro prototype eschews an awesome multi-carb gasoline engine in favor of Infiniti's EV technology. It's unclear if the car actually runs, but we'd all love to see this put some laps down at nearby Mazda Raceway Laguna Seca. Related Video:

Infiniti Prototype 9 is a wonderfully beautiful EV grand prix car

Few automobiles are as elegantly beautiful as the open-wheel grand prix cars of the 1940s, '50s and '60s. The simple, slender shapes of these cars bear no extravagant flourishes or adornments. The purposeful design is what gave these cars their beauty, and it's these classic machines that inspired the new Infiniti Prototype 9. Teased earlier this week, this concept blends old and new, with classic lines hiding a modern all-electric powertrain. The Prototype 9 will make its full debut next week at the 2017 Pebble Beach Concours d'Elegance. Infiniti says the car was built around a simple idea: what would a 1940s Infiniti grand prix car look like? While the silver paint may be more German than Japanese, the design could easily be mistaken for an actual '40s grand prix car. Only the Infiniti-styled grille gives it away. Everything about it, from the thin bias-ply tires wrapped over center-locking wire wheels to the bulging screws around the driver's seat, is pitch perfect. Underneath that achingly long hood rests a prototype electric motor and battery from Nissan's Advanced Powertrain Department. The combo sends 148 horsepower and 236 pound-feet of torque straight to the rear wheels. That's good enough to send the svelte 1,962 lb car to 62 mph in just 5.5 seconds. Top speed is right at 106 mph. While speed may die off towards the top end, all that torque and a 43/57 front to rear weight distribution should make the Prototype 9 a riot on a small, tight circuit. There's only enough juice in the battery for about 20 minutes of flat-out racing. The handmade steel body rests on a steel ladder-frame chassis. The front suspension uses a leading-arm rigid axle with transverse leaf spring while the rear uses a De Dion axle, also with a transverse leaf spring. The Prototype 9 also uses old-school hydraulic rotary type dampers. There's no power steering and no brake booster for the four-wheel disc brakes. The car was designed and built by a number of different departments within Infiniti and Nissan. A simple sketch expanded as more and more designers and engineers wanted to have a hand in the project. The steel body panels were all shaped and hammered by hand. The bare cockpit is only adorned with a thin seat, three gauges, a few switches, a gear selector and the steering wheel. The gauges are set into a fixed aluminum hub in the center of the steering wheel.
