Infiniti Pebble Beach retro concept is a '50s-inspired electric grand prix car

Infiniti will debut a retro-inspired race car at next week's Pebble Beach Concours d'Elegance that combines the style of classic grand prix open-wheel cars with modern design elements and powertrains. The car should fit right in at Pebble Beach alongside all the vintage machinery from the early days of motorsports. Simply dubbed the Infiniti retro prototype, it is Infiniti's idea of what could have been. Basically, the Japanese automaker imagined that it found a car hidden away for 70 years in southern Japan. They took that old look and married it with the brand's "Powerful Elegance" design language. We only have a couple of photos, but it looks like a sleek silver bullet with narrow-section bias-ply tires. We'll have to wait until next week to see the entire thing, but this teaser has us excited. As expected with any modern concept, the retro prototype eschews an awesome multi-carb gasoline engine in favor of Infiniti's EV technology. It's unclear if the car actually runs, but we'd all love to see this put some laps down at nearby Mazda Raceway Laguna Seca. Related Video:

Infiniti Q30 prototype has entry-level luxury in the bag

The Infiniti Q30 Concept signaled the Japanese brand's clear intentions to join the growing global compact premium segment. Now, as evidenced by these images, we can see development of the brand's first compact hatchback is proceeding apace.
Our spies point to the similarity between this camouflaged tester and the Mercedes-Benz GLA-Class as further evidence to the cars' shared platform, although we'll admit, we don't necessarily see the similarities. The Q30's overall look, to our eyes, is like a scaled-down, lower-riding QX50, the model previously known as EX. Infiniti design elements, like its squat greenhouse, long hood and double-arch grille are all visible.
The Mercedes-Benz connection should be clearer under the hood, though, as the Q30 is expected to be powered by the same 2.0-liter, turbocharged Mercedes four-pot that's been leading the charge throughout the brand's entry-level models, namely the CLA-, GLA- and C-Class.

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:
