Infiniti Q50 Eau Rouge portends seriously powerful future sports sedan

"If we built this car I would expect it to feature over 500 horsepower and 600 pound-feet of torque."
Eau Rouge is a notoriously difficult turn at Belgium's Spa-Francorchamps Circuit that is capable of striking fear into the hearts of the most hardened driver. Naming a car after something so terrifying, therefore, strikes us as a rather poor idea.

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:

Infiniti EV delayed to add better tech

An evolution in lithium-ion batteries and "interesting advances in electric technology" are said to be responsible for the delay of Infiniti's electric car, the production version of the LE concept first shown at the New York Auto Show in 2012. At the time of its introduction, Infiniti said we'd have a version we could buy within two years; that timeline became 2015, and now Automotive News Europe reports that it's"still within in our mid-term plan" but officials aren't saying how long the delay will be.
When shown, the LE had a 24kWh lithium-ion battery and a 100kw electric motor producing 134 horsepower and 240 pound-feet of torque, a 100-mile range and the potential for wireless charging. It isn't clear if the postponement will bring improved specs or perhaps improved packaging and technology - or both. All we have for now is that the new timeframe is "not significantly" beyond the original plan.
