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:

Watch the 2022 Infiniti QX55 reveal livestream at 8:55 p.m. EST right here

The car reveals are coming in quick succession today, and last up is the 2022 Infiniti QX55. Infiniti will be hosting a stream at 8:55 p.m. ET tonight to reveal the crossover coupe version of its popular QX50. Artist Aloe Blacc will be hosting the event and hyping the car up from the Belasco Theater in Los Angeles. Additionally, Infiniti will have designers and executives on hand to speak about the car and its development and background. If this reveal is anything like the Nissan Z Proto reveal, expect a number of folks on hand and a detailed look at the crossover. You can watch it all in the video stream at the top of this post via YouTube. We already know what to expect coming into this reveal, thanks to a recent teaser from Infiniti and spy shots (see the gallery below) captured at the beginning of the year. It’s going to look like a chopped and coupe-ified QX50. The VC-Turbo engine should be under the front hood, and “shifting” will likely be handled via a CVT. Check back with this post just before 9:00 p.m. ET to see the video reveal, then head on over to our full reveal post on our home page where you can get a more detailed breakdown of whatÂ’s new and different in the QX55.

Race Recap: Singapore Grand Prix is about a safety car and submission

The Singapore Formula One Grand Prix is the Monaco GP of the Orient - a weekend known more for its glamour and time-slot than on-track action, with a temporary circuit that punishes every mistake, usually terminally.
Lewis Hamilton in the Mercedes-AMG Petronas got the best of Free Practice 1, opening the curtain on a possible resurgence of Silver Arrows performance. By the time qualifying was done, though, it was his teammate Nico Rosberg who lined up second on the grid, followed by Romain Grosjean with a beautiful performance in the Lotus, Mark Webber in the Infiniti Red Bull, and Hamilton all the way back in fifth. Behind them were Felipe Massa outqualifying Ferrari teammate Fernando Alonso, Jenson Button getting the McLaren into eighth, Daniel Ricciardo with another good Q3 effort to get into ninth, and the shocker of Esteban Gutiérrez getting his Sauber into the top ten for the first time this year.
At the front of the pack was Sebastian Vettel. Again. But he was only ahead of Rosberg by a single tenth of a second...
