Vettel and Coulthard drive Russia's very unfinished Sochi Circuit

The next Winter Olympics will happen in Sochi, Russia from February 7-23, 2014. Sometime after that, barring any delays, a portion of the Sochi Olympic Park will be turned into the Sochi Olympic Park Circuit, a 3.65-mile track for the first Russian Grand Prix in 100 years (the last of two Formula One grands prix were held in St. Petersburg).
As we've come to expect from the Infiniti Red Bull team, it recently sent Sebastian Vettel and brand ambassador David Coulthard to the unfinished venue to run the route in Infiniti M sedans and offer some impressions. With average cornering speeds above 62 miles an hour, Coulthard called it a fast street circuit in the Monaco vein. You can watch them try it out - yes, that's Vettel gone airborne above - and avoid a "White Van Man" in the video below.

2019 Infiniti QX60 and QX80 Limited, now with more chrome, Alcantara

Just ahead of the New York Auto Show, we get our first glimpse at new trims on the 2019 Infiniti QX60 and the refreshed 2019 Infiniti QX80. The Limited trim is the range topping spec for both crossovers and adds some new colors, trims and visual changes you won't find on lower-tier models. Pricing hasn't been announced, but the new models will be on sale this summer. The QX60 is Infiniti's best-selling model. The 2019 QX60 Limited has a new dark chrome finish on the grille, fog lights and door moldings. The roof rails, cross bars and rear bumper also get a darker finish. There are new 20-inch wheels that are exclusive to the Limited model. Inside, the QX60 Limited gets new trim with contrasting stitching, leather-wrapped grab handles, dark silver wood accents, quilted leather seats and door panels, and unique floor and cargo mats. Similar treatments can be found on the 2019 QX80. The Limited model gets 22-inch wheels, stainless-steel running boards, satin chrome trim and roof rails, and a unique design on the front and rear bumpers. There's also one exclusive paint color, Anthracite Gray. Inside, the QX80 Limited has a two-tone leather and Alcantara interior. It also gets some slick looking matte-silver wood trim. Other features include illuminated kick plates, puddle lights and special floor and cargo mats. Related Video: This content is hosted by a third party.

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:
