Watch Sebastian Vettel become first driver to lap Sochi GP circuit

In April of last year, Sebastian Vettel and David Coulthard drove the unpaved Sochi Formula One circuit in a pair of Infiniti M sedans, getting both muddy and airborne in the process. Now with tarmac laid down and fences put up, Vettel and Coulthard have gone back to the Black Sea vacation spot for another hot lap, this time in a Q50 Hybrid and without the need for mud flaps.
Sochi has earned the blessing of F1's race director, so now the next test will be the fans. With a healthy amount of wall-and-fencing along the straights, it has shades of Valencia for the viewer. We hope it will be much more exciting than its Spanish counterpart when racing happens on October 12. You'll find more videos below covering Infiniti's visits to the Sochi Autodrom, and a press release on the latest lap.

Infiniti's variable compression engine in the 2019 QX50 is the first of its kind

The world's first variable compression ratio engine is here, in a production car. That car is the 2019 Infiniti QX50, debuting this week at the Los Angeles Auto Show. The midsize crossover has seen a refresh that has brought it an all-new platform together with new driver assist features, but it's the engine that's the centerpiece here. Nearly everything is continuously variable under the hood of the QX50 – not only the new shift-by-wire XTRONIC CVT. The new VC-Turbo gasoline engine is able to change its compression ratio from 8:1 to 14:1, or anything in between depending of the driving situation; whether there is need for top-end power or turbodiesel-like torque from low revs, or optimized fuel economy. The pistons' reach is continuously adjusted by an electric "Harmonic Drive" motor, which controls a multi-link system, affecting the top-dead-center of the pistons and changing the compression. The engine can also switch between efficiency-maximizing Atkinson cycle and regular combustion cycle, on the go – and there's both multipoint injection and gasoline direct injection employed. The result is 268 horsepower at 5,600 rpm and 280 pound-feet of torque at 4,400 rpm; good figures for a 2.0-liter four-cylinder gasoline engine with a single-scroll turbocharger. Infiniti says that the FWD version's fuel economy of 27 miles per gallon combined is 35-percent better than the previous-generation V6 engine; in AWD guise, it reaches 26 mpg, which is a 30-percent improvement. The new engine is pretty much all-aluminum, but the vaguely magical-sounding "transformative multi-link components" behind the variable compression system are made from high-carbon steel alloy. The engine's multi-link system also enables it to do away with any balancing shafts, and Infiniti compares its smoothness to a V6 rather than a regular four-cylinder. In addition to the aforementioned tech, the VC-Turbo engine has the world's first active engine mount vibration damping system to smoothen its operation even further. Related Video:

Infiniti QX Inspiration crossover EV is another step toward a grille-less future

Infiniti has released its first image of its Detroit Auto Show concept car, and unsurprisingly, it's electric, and it's a crossover. Also, just as Nissan's design vice president hinted at last year, it pushes the design ideas of the Q Inspiration sedan concept a little farther, and in an arguably more controversial direction. Whereas the Q Inspiration concept had a mostly closed off grille with only a few openings, it was also still set back in a clear grille design. The QX Inspiration concept leaves the entire front end perfectly flush. There are still hints of a grille with metallic trim at the top and bottom that suggest a classic Infiniti grille shape, and the badge and logo float in the middle to further the idea. It's an interesting idea, but the ideas of having a grille and going without seem to be a bit at odds, and the result is a bulbous, flabby nose that doesn't flatter either design philosophy. We suppose it could be worse, though, and it may look better in person. What we don't question is the product type. An electric crossover seems like the exact vehicle the car market is looking for. Infiniti hasn't gone into detail about powertrain specifics besides it using electricity and that it previews future electric platforms. Nissan's design V.P. noted that the company will be introducing more full electric vehicles, and this concept could feature an e-Power series hybrid powertrain in which the gas engine mostly exists as a generator. So it's possible that a future Infiniti crossover EV could be offered in full electric and range-extender variants. We'll have more information and photos when the QX Inspiration makes its official debut at the Detroit Auto Show on January 14. Related Video: This content is hosted by a third party.
