Infiniti Prototype 10 single-seat speedster unveiled at Pebble Beach

PEBBLE BEACH, Calif. — Infiniti's new Prototype 10 takes inspiration from last year's Prototype 9 concept, but instead of minimal bodywork and open wheels, adopts the long and sinuous profile of classic speedsters of the past. And the concept's electric powertrain hints at the Japanese automaker's future. Infiniti says that all new production models from 2021 onward will have some sort of electrification, spread across pure battery-electric vehicles, parallel hybrids and e-POWER series hybrid powertrains. The overall shape of the Infiniti Prototype 10 recalls classic race cars like the 1950s-era Jaguar C- and D-Types. There's virtually zero wind protection for the single passenger, but there's a prominent headrest that incorporates a fin-shaped aero element. Air intakes are plentiful and festooned with close-set vertical bars that remind us of last year's Prototype 9 concept. There are lots of striking details in the Prototype 10's flowing bodywork. Slim, almost slit-like lights up front sit below the level of an Infiniti logo highlighted by negative space. In profile, a virtual line cuts across the vehicle front to rear. We look forward to seeing how some of these elements are incorporated into future production vehicles from Infiniti. View 17 Photos We don't have any details on what's actually powering the Prototype 10 as its sits, other than the fact that it's electric, of course. But we do know that the concept uses Infiniti's steer-by-wire Direct Adaptive Steering system. We can also see that the interior compartment is minimalist in design, clearly in an effort to keep the driver's focus firmly on the road ahead. Though much of the commentary surrounding the Prototype 10 will undoubtedly be about its radical bodywork, it may be the vehicle's chassis that is most relevant to Infiniti's production electric vehicle plans. The company describes the Prototype 10's chassis as rigid, modular and flexible with a flat floor and says such a platform would underpin its future electrified vehicles, including sedans, SUVs and sportscars. Stay tuned for more on the Infiniti Prototype 10 as we meander the remainder of Monterey Car Week here in California. Related Video: This content is hosted by a third party.

Infiniti to get Leaf-based electric sedan after all

Infiniti suffered a huge blow a few weeks ago when CEO Johan de Nysschen jumped ship after two years on the job to take the helm at Cadillac. As boss, he spearheaded change within the Japanese luxury brand and was among the biggest champions of the Q50 Eau Rouge. However, the company is far from sunk. Plans put in place prior to de Nysschen leaving are still on the table, according to Nissan product planner Andy Palmer to Automotive News, and that could mean a rosy future for the once AWOL LE sedan (pictured above) and other models.
Back in 2012, Infiniti promised that it would have the LE on the market as a premium electric sedan by 2014. It was supposed to share the battery pack with the Nissan Leaf but with a more powerful, 134-horsepower motor. But have you seen one on the road recently? The luxury EV was eventually shelved, but de Nysschen pledged the idea wasn't dead. Maybe now is a better time for it. According to Automotive News, the LE is rescheduled to launch in 2017 or 2018. The latest version would use the Leaf platform but with a more potent, next-gen battery to give it a range over 90 miles.
Of course, the LE isn't the only thing on the way from Infiniti; it also appears to be planning a two-pronged approach for small cars. Palmer recently tweeted that the company would build the forthcoming Q30 hatchback and QX30 crossover in the UK in 2015. Additionally, the automaker is firing up a new joint venture factory in Mexico with Mercedes-Benz; building compact models there starting in 2017. According Automotive News, the Mexican-built models will be more US-focused while the UK-built ones will appeal more to Europeans.

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:
