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:

Red Bull Racing unveils RB10 as pre-season testing kicks off

Ladies and gentlemen, here's the car that will win the 2014 Formula One World Championship... probably. Maybe. The success of Red Bull Racing over the past several years means that the debut of its 2014 challenger is one of the more note-worthy events of the preseason, showing off the latest piece of aerodynamic mastery from Adrian Newey.
Like the Ferrari F14 T, the Red Bull RB10 features a more conventional nose, which still plunges rather dramatically ahead of the front wheels. We're seeing a very interesting split early in the season between the top teams like Red Bull and Ferrari, who are opting for a more traditional design, and the mid-pack challengers, which are being more aggressive with their aerodynamics. Seeing how this plays out during the season will be very interesting. As for RBR's design, it's attractive, but wasn't easy to pen, according to Newey, who found the turbocharged V6s a difficult piece in the new F1 puzzle.
"Whereas the V8s were a very well-known package, with these power units, the engine itself is easy enough to install, but then of course you've got the turbocharger, the intercoolers, and the electrical side in terms of the motor generator units and much bigger batteries," Newey told the official Formula One website.

Infiniti's Palmer announces QX30 small crossover production

The name of the game these days in the luxury marketplace is premium compacts. BMW has the 1 Series and 2 Series, Mercedes the A-Class, B-Class, CLA and GLA, Audi has the A1 and A3, even Lexus has the CT 200h. Among the last to get in on the action is Infiniti, but that's all about to change.
Nissan's luxury brand has been working towards a premium compact for some time, revealing the Q30 concept at the Frankfurt Motor Show last year and signing a new deal with Daimler to help develop and produce it. Now it seems that both it and a crossover version have been approved for production.
The news comes from Andy Palmer, Nissan's UK-based COO, chairman of Infiniti and one of the company's top executives under CEO Carlos Ghosn. Late last week Palmer tweeted the following:
