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:

8 fastest depreciating cars in America

Getting a new car is an amazing experience. The fresh new scent, the barely touched interior, the double digit miles on your odometer, and... the depreciation once it leaves the car dealers lot? Maybe not that last one. To save you from the hurt of a quickly depreciating new car, we collected 8 of the fastest depreciating cars in America. And here's a surprise, one of them is a Toyota.

Another Infiniti Q30 image found ahead of Frankfurt debut

Infiniti will introduce the new Q30, its smallest vehicle ever and its first foray into the compact, premium hatchback segment, next month at the 2015 Frankfurt Motor Show. The company confirmed the debut when it issued a single image of the new car last month. Now, we have a second shot. Released by the Twitter account of Infiniti's British outfit, the new shot is part of the #Q30Challenges campaign, which asks users to pick an object they'd like to reinvent. It shows the stylish hatch in the same bronzish-brown hue featured in the first image, but gives us a very wide front three-quarters view. We can see Infiniti's trademark C-pillar treatment, as well as a pair of wavy character lines. The shot also provides an especially good view of the Q30's long hood. The Q30 enters a segment that's nothing if not competitive, even here in the United States where small cars are a relatively recent phenomenon from premium automakers. Audi offers its A3, BMW is in the game with its 2 Series, Mercedes has its CLA and GLA and Lexus competes with the long-running CT 200h. The Q30 will be part of a two-pronged attack that will also include a QX30 crossover. We'll have a whole heap of additional information and images of the all-new Q30 when it makes its global debut next month in Germany. Stay tuned.
