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:

2015 Russian Grand Prix was full of crashes and DNFs

Mercedes-AMG Petronas non-executive chairman Niki Lauda said of Lewis Hamilton's race-day domination this year, "The guy is driving like a god." Qualifying is another story, though – teammate Nico Rosberg taking pole proved that sometimes deities have to settle for second on the grid. Williams driver Valtteri Bottas surprised himself and his team with third place, half a second behind Hamilton but 0.05 sec ahead of the first Ferrari driven by Sebastian Vettel, while a mistake on Kimi Raikkonen's final flying lap left him in fifth, 0.4 sec behind Vettel. The Sahara Force India team had a good showing, with Nico Hulkenberg qualifying sixth just ahead of teammate Sergio Perez in seventh. It's the first time they've had both drivers in the top ten on the grid since the 2014 British Grand Prix. Romain Grosjean is leaving the stormy waters of Lotus at the end of the year for the unknown waters of Haas F1, but he made the shoestring operation look really good before Renault takes over by taking eighth place on the grid. Max Verstappen qualified well again with ninth in the Toro Rosso, ahead of the first Infiniti Red Bull Racing of Daniel Ricciardo in tenth. Red Bull driver Daniil Kvyat lined up eleventh for his home grand prix, certainly a disappointment after locking up fifth place on the grid last year in a Toro Rosso. When Pirelli brought soft and supersoft compounds to Sochi, the company said it hoped this year's race would be better than last year's. We're sure this first-lap mishap isn't what they meant. Rosberg and Hamilton dragged it down to Turn 1, with Rosberg getting the inside line. Hamilton had to go wide at Turn 2 as Rosberg fought to hold position, but they left a mess in their wake: Hulkenberg spun going into Turn 2 and stopped in the middle of the track, and Marcus Ericsson in the Sauber – who'd started 16th – collided with him. Both cars were out of the race immediately, and the Safety Car came in. The Safety Car returned to the pits on Lap 3 Rosberg led the field, but just two laps later the German complained of a sticking throttle pedal. Two laps later he had to retire, unable to drive the car properly. That put Hamilton at the front, and we've seen that race a bunch of times before. He built a double-digit lead and never lost it.

Infiniti invites 22-year-old to work with Red Bull F1 team

Infiniti launched the Infiniti Performance Engineering Academy (IPEA) in 2014, a global talent search for three engineering students from eleven international markets that the automaker would select for a one-year assignment with its Formula One team and road car division. The second year's IPEA competition has concluded, the class of 2015 expanding to five students that get eight months at Infiniti Red Bull Racing headquarters in Milton Keynes, and four months at the company's European Technical Center in Cranfield, UK. Twenty-two-year-old Alex Allmandinger (pictured), a student at the University of Illinois and one of 11 US finalists, is one of those five winners. He'll head to Milton Keynes next month to settle in with the other winners from China, Europe, Russia, and Saudi Arabia. Based on interviews with last year's winners, the IPEA doesn't stick the students in a corner, either – one of them said he had designed seventy parts that went into the RB11 F1 racecar. The video above speaks to some of this year's winners, the video below talks to last year's, and there's a press release below that. This content is hosted by a third party.

Aug. 20, 2015 – Infiniti has announced that an engineering student from the University of Illinois is one of five global winners of the 2015 Infiniti Performance Engineering Academy (IPEA). For one year, Infiniti will provide 22-year-old Alex Allmandinger with the opportunity to work in Formula One with the Infiniti Red Bull Racing team. After beating 11 other finalists from around the country in an intense shootout event, Allmandinger will move to Infiniti Red Bull Racing headquarters in the UK in September to begin a 12-month placement working with the four-time Formula One World Championship Infiniti Red Bull Racing team, as well as with Infiniti. Allmandinger will spend eight months working on Vehicle Design at the team's headquarters in Milton Keynes, UK – and four months working at Infiniti's European Technical Center in Cranfield – on road car development projects. Formula One technology is more relevant to the automotive industry than ever and will play a key role in the ongoing transfer of technical knowledge and expertise between the race team and Infiniti.
