Infiniti-Red Bull Racing will seek a fourth title with the RB9 [w/video]

This is the car and the team that everyone wants to dethrone. The stability of this year's regulations means that the Infiniti Red Bull RB9 is a seriously honed RB8; however, that's a situation probably no other team would complain about seeing that the RB8 recovered from early stumbles and reliability issues last year to carry Sebastian Vettel to a third consecutive driver's title and the team to a third consecutive constructor's trophy.
The most noteworthy revisions to the car are the partial vanity panel that omits the driver cooling slot, the even narrower rear end - a feature of just about every car launched so far - and purple sidepods to showcase new title sponsor Infiniti. Adrian Newey, perhaps the most feared designer on the pit lane, said the nose and front wing could be changed relatively easily throughout the season, but he wanted to make sure to get the middle of the car - everything from the sidepods, back - as good as possible since they're more difficult to re-engineer. His track record leads us to believe he did just that.
Below are two videos, one of the making of the RB9, the other the launch at team headquarters in Milton Keynes.

Infiniti and Steph Curry team up for hilarious 'ugliest car ever' prank

Stephen Curry, the famous Golden State Warriors basketball player, and Infiniti just pulled an epic and cringeworthy prank on Curry's friend COSeezy. In case you hadn’t noticed the commercials, Curry is a brand ambassador for Infiniti, so heÂ’s pretty tight with the Japanese luxury brand. The MVP invited his friend over to help him shoot a commercial for a mysterious new Infiniti concept car that Curry “helped design.” COSeezy was there to react to what would surely be an incredible piece of machinery. What Curry ended up showing him was a GO-4. You may have seen one of these crawling along city streets doing the odd job or two, and thereÂ’s absolutely nothing glorious about them. Curry dressed this particular GO-4 out with one hell of a body kit in an attempt to fool COSeezy into thinking it was a fancy new concept car. And he succeeded. Take a gander at the footage and have a laugh for yourself — things get rather awkward and embarrassing for COSeezy as the video goes on. But hey, thatÂ’s what pranks are for. In case you were wondering, the luxurious GO-4 features a 1.0-liter three-cylinder engine that puts out 66 horsepower. It has a four-speed automatic transmission and achieves a claimed 45 mpg. The vehicle looks ridiculous, though, and thatÂ’s pretty much all that matters here. Infiniti did pull an actual concept car out of a nearby garage after they let COSeezy know it was a prank. They had the QX Inspiration Concept on hand — itÂ’s the crossover Infiniti showed at the Detroit Auto Show this year.

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:
