Infiniti sees a bright future for the luxury sedan

One of the four new models that Infiniti will release in the coming years is an electric sedan previewed by the Vision Qe concept. Investing in a body style that many of the brand's peers and rivals are pivoting away from might sound odd, but executives at Infiniti still see a demand for sedans. "For the U.S. market, the sedan segment is still a very relevant segment. We have a ton of history, and heritage, and hugely passionate fans. So with that kind of passion, we're always getting asks for that kind of piece," Bob Welby, Infiniti's senior director of operations, told Motor1. The publication cited older, Nissan Z-derived sedans like the G35 and the G37 as models that could inspire Infiniti as it brings its first electric sedan to the market. These cars were aimed squarely at European sport sedans like the BMW 3 Series, and they put a much bigger focus on performance than on comfort while remaining pegged on the luxury side of the spectrum. They enjoy a relatively loyal following in 2023. Later known as the Q40, the G37 retired at the end of the 2015 model year and passed the torch to the Q50, which remains in production today but has nearly reached the end of its life cycle. When it retires, it will leave the Nissan-owned brand without a sedan in its range for the first time since its inception: The bigger Q70 retired at the end of the 2019 model year and the full-size Q45 was axed after 2006. In contrast, the current Infiniti lineup includes four SUVs. This focus on high-riding models won't change, even if the sedan sticks around. "SUVs have become another emerging strength of ours over the past decade," Welby said. "That's absolutely going to be part of our story." The next-generation QX80 is notably around the corner. Infiniti previewed it with a close-to-production concept called QX Monograph.   Green Infiniti Electric Sedan

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:

At long last, Infiniti plans a production EV

After years of false starts, it appears that Nissan's Infiniti division will finally launch a production electric car in 2019 and debut it as a concept in January at the North American International Auto Show in Detroit. Details at this point are scant, but Infiniti Executive Design Director Alfonsa Albaisa told Autocar the EV would be an all-new electric-only vehicle based on a new platform. Citing the company's grand prix-inspired Prototype 9 racecar concept that was shown a few weeks ago at Pebble Beach, Albaisa said consumers would see "parts of the car in a different context" on the concept EV. The Prototype 9's all-electric powertrain was developed by parent company Nissan's Advanced Powertrain Department. The last we saw of any electric offering from Infiniti was way back in 2012 with the LE Concept sedan, which was supposed to show up in dealerships two years later. Those plans were initially postponed in 2013 and then again in 2015 amid doubts over EV sales projections and larger concerns over boosting overall Infiniti sales. The LE had a 24 kWh lithium-ion battery pack paired with a 100 kilowatt electric motor delivering 134 horsepower and 240 pound-feet of torque.
