Nissan backing off IDx, BladeGlider and Infiniti Eau Rouge amid focus shift

Nissan and Infiniti are officially under the microscope after their presentations at the 2015 Detroit Auto Show focused on the new Titan pickup and Q60 Concept, but lacked any and all mention of allegedly production-bound examples of the Q50 Eau Rouge, IDx and BladeGlider EV concepts. Automotive News reports that the lack of info on the three concept cars, which had previously heralded a more performance-minded Nissan/Infiniti, has signaled a shift in priorities at the Japanese company. Instead of driver-oriented models, emphasis is seemingly being focused more on volume offerings. Nissan was subject to a pair of high-level executive departures last year, with both Andy Palmer and Johan de Nysschen departing for Aston Martin and Cadillac, respectively. Both execs were strong proponents of more driver-oriented offerings, with Palmer championing the compact, rear-drive IDx coupe and de Nysschen backing the high-performance Q50 Eau Rouge. While Palmer has been mum on his former employer's alleged move away from performance, de Nysschen made headlines last month after calling out a Nissan vice president in a Facebook post saying he "heard a rumor that Noboru Tateishi is going to cop-out and shelve the Eau Rouge project now that I'm not there to pressure him," while adding that the VP has "more enthusiasm for 'driver's aid's,' apparently, than 'driver's cars.'" AN reached out to Infiniti, with North American VP Michael Bartsch telling the publication that no decision had been reached about the Eau Rouge and that the company was more focused on rebuilding its core portfolio.

New details emerge on Inifiniti QX50’s unique new variable-compression engine

Infiniti will release the world's first production variable-compression engine when it releases the 2019 QX50 midsize SUV sometime next year. Now we have some new details on the innovative new engine, which Infiniti is calling VC-T, for Variable Compression Turbo, after the luxury brand offered a prototype test drive. We wrote extensively about the complicated technology underpinning the new engine last year. It's the latest novel development that could represent a range-extender, if you will, for the embattled internal combustion engine in an era when automakers and governments are shifting their focus to electric vehicles. The VC-T is a new inline-four, 2.0-liter that combines the power of a high-performance turbo gasoline engine with the torque and efficiency of an advanced diesel engine, but without the latter's notorious emissions. It features the ability to seamlessly raise or lower the stroke of the pistons in the combustion chamber, depending on the driving conditions it detects and inputs from the driver, to select the best compression ratio—anywhere between 8:1, typical for high-performance engines, and 14:1 for high efficiency. In essence, it delivers the performance of a V6 but is much more efficient, with improved fuel efficiency of between 10 to 15 percent with its best competitors, per Car and Driver.

It's also quieter, more lightweight and compact than V6 engines with comparable power outputs, estimated at 268 horsepower and 288 pound-feet of torque. In a prototype test drive, Car and Driver writes that the engine "felt very conventional" and responsive, with strong and smooth acceleration. "The only indication you have that the compression ratio is changing is from an indicator in the instrument cluster next to the boost gauge." The engine is expected to deliver fuel economy gains of 27 percent in combined city-highway EPA rating over the outgoing QX50, which had a 3.7-liter V6. The 2019 model, fitted with the VC-T, should get about 26 mpg in combined fuel economy, and it will get to 60 mph almost one second faster than its four-cylinder counterparts, Nissan's chief powertrain engineer, Shinichi Kiga, told Automotive News. The VC-T engine is the result of 20 years of development spanning more than 100 prototypes and around 300 patents at Nissan.

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.
