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.

Infiniti shows Q30 interior ahead of Frankfurt debut

Infiniti is supposed to debut the all-new Q30 hatchback at the 2015 Frankfurt Motor Show, but as the show is still a couple of weeks away and the company has elected to release yet another image, we aren't sure there'll be all that much to see come Sept. 15. With that in mind, then, we give you the first images of the entry-level hatch's cabin, and they're, um, wow. We knew the Q30 had a lot in common with the Mercedes-Benz A-Class but as these images show, this is far more than a common platform. The steering wheel, instrument cluster, switchgear, and shifter are direct from the Mercedes parts bin. From the looks of the images, the Q30 will even have a Mercedes-style key. This might not garner much attention in the budget ranks – take the Scion iA and Mazda2, for example – but this degree of parts sharing in the premium market is sure to raise some eyebrows. It's also a rather bewildering move for Infiniti. The company is, in effect, selling a Mercedes-Benz to any new customers it attracts. That'll certainly make a Q50 a hard sell when it comes time for an upgrade. Now, in Infiniti's defense, there are some differences in the layout here. The triple nozzle-style HVAC vents have been replaced with a more conventional pair of outlets, and the instrument cluster hood extends over the built-in navigation screen. That design decision, in particular, will certainly appeal to critics of the tacked-on-tablet look offered by Mercedes. The analog buttons for the multimedia system have also been tweaked, with the result looking far cleaner than the mess of buttons offered on Mercedes' products (we wouldn't be shocked to see this layout arrive on a facelifted A-, CLA-, or GLA-Class in the near future, though). Beyond those changes, though, there are multiple Mercedes design hallmarks here, including the location of the controls for the seat adjustments. You can check out the Q30's cabin in both right- and left-hand drive varieties courtesy of the images above. And for comparison's sake, we also included our most recent gallery of the Mercedes-Benz GLA-Class at the bottom of the page. Have a look and be sure to scroll down for the official press release.

2015 Japanese Grand Prix is a little Mercedes, a lot of zen

Just one week on from the issues in Singapore Mercedes-AMG Petronas appeared to have solved its clamp problems and everything else. Daniil Kvyat at Infiniti Red Bull Racing took the two Free Practice scalps on Friday, but when it came time for qualifying the front of the grid looked really familiar: Mercedes' Nico Rosberg took his second pole position of the season, Lewis Hamilton next to him in second. Kvyat had a hand in that, too, the Russian getting into a big accident in Q3 when he put two wheels on the grass heading into the hairpin and veered into the tire wall so hard that he flipped. That ended qualifying before a number of drivers had a chance to improve their times, Hamilton among them. That's how Valtteri Bottas got in third for Willliams ahead of Sebastian Vettel fourth for Ferrari. Felipe Massa had the second Williams in fifth, ahead of Kimi Raikkonen in the second Ferrari. Daniel Ricciardo lined up sixth for Infiniti Red Bull Racing, a team we're going to have to enjoy watching for the rest of the season since it might not exist come 2016. Romain Grosjean gave Lotus some good news by getting into eighth, the team so strapped for cash that it couldn't get into its hospitality area, so it held press conferences outside and ate at Bernie Ecclestone's Paddock Club. Sergio Perez took ninth for Sahara Force India, and Kvyat slotted into tenth after not setting a time. The Russsian's race would begin from the pit lane once his mechanics rebuilt his car. It wouldn't be a Formula One start lately without someone at the front having clutch problems. This time it was pole man Rosberg, whose power unit got too hot and put him a few horsepower down on Hamilton through Turns 1 and 2. That's half of how Hamilton took the lead from the lights going out, and the Brit kept it throughout the race. Rosberg, however, said his race was lost when Hamilton pushed him wide through Turn 2, a move Hamilton defended. Rosberg finished almost 19 seconds behind his teammate, a gap that probably isn't fully explained by that opening incident. Hamilton's race was so uneventful that we almost never saw him on camera – that is, we saw him so much less than we usually see him when he's out in front and unpressured that Nikki Lauda said he'd ask Ecclestone why the cameras avoided him. The conspiracy theory holds that FOM was punishing Mercedes for not supplying Red Bull with engines next year.
