Watch 14 hot rides take over concept car lawn at Pebble Beach

The Pebble Beach Concours d'Elegance is an annual celebration of the beautiful, old cars that grace Monterey Car Week. But Monterey – and Pebble – features lots of newer metal, too, and that includes the concept lawn at Pebble Beach. Now, "concept lawn" isn't a totally accurate name anymore, and you'll see why in the list below. This year especially, plenty of production cars can be found in the area once reserved for the conceptual. Still, we're happy to see them. Here's what's featured this year: Alfa Romeo 4C Spider Audi R8 BAC Mono Bentley EXP 10 Speed 6 BMW 3.0 CSL Hommage R Buick Avenir Galpin-Fisker Rocket Speedster Hyundai HCD-16 Vision G Coupe Icona Volcano Infiniti Q60 Lamborghini Asterion LPI 910-4 Maserati Ghibli McLaren 570S Rolls-Royce Wraith By our count, that's seven concepts out of fourteen cars. But it still makes for one hot group of metal. Check 'em out in the gallery above.

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 QX55 spied for the first time looking sleek

The Infiniti QX55 is well on its way to joining the crossover coupe ranks in 2020, and here’s our first view of the car out testing. Infiniti is expected to debut the ‘ute in the first half of 2020, so it wonÂ’t be long till we see it without the swirls and body cladding on it, too. As the name suggests, the QX55 is a derivative of the QX50 crossover, which was just completely redesigned for the 2019 model year. Infiniti debuted its new VC-Turbo (variable compression) engine technology in that crossover, and itÂ’ll certainly be along for the ride in the QX55 as well. The latest teaser suggested that Infiniti would be greatly differentiating this crossover coupe to the rest of the field by giving it a uniquely long tail for more cargo space. That tail still exists on the vehicle caught out testing, but it doesnÂ’t look drastically different than other vehicles of its ilk. To that end, rear cargo space is likely to be slightly down from the more traditionally shaped QX50, even if itÂ’s slightly better than competitors. However, rear seat space appears to be better than expected. The roof itself doesnÂ’t taper at a horribly steep angle into the rear passengerÂ’s heads, and the rear windows are large enough that they may only cause minor claustrophobia. Most of everything except for the rear end will likely resemble the QX50 verbatim, so itÂ’s just the back half that weÂ’re waiting for in the reveal. The grille itself has the same waveform shape as the normal QX50, and the body creases in the hood and doors protruding through the skin-tight camo resemble it as well. Even the wheels on this tester are exactly the same design as the rollers used on the production QX50. When it does come out, the QX55 will join its German competition in this stylish but utility-hampered segment. The BMW X4 and Mercedes-Benz GLC Coupe will be the main targets when we expect this car to hit dealer lots later this year. Related Video:
