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 Q30 will debut at Frankfurt Motor Show

The Infiniti Q30 made its debut as a svelte concept at the 2013 Frankfurt Motor Show. Now, two years later, the luxury hatchback will make a big return to the German show in September to launch in production guise. Before the end of the year, the first Q30s will start showing up for sale in European showrooms to take on rivals like the Audi A3. To tease the launch, Infiniti has released this single image of the Q30 going through final validation testing on the road. Unfortunately, it's still wearing a very effective camouflage pattern – just like some previously spied examples. Still, we can tell that there are definite similarities to the hatchback's stylish QX30 compact crossover sibling, which is also on the way. Both of them have sharply pointed, narrow headlights and steeply raked hatches. We can also just make out the deeply creased swage line that cuts through the front door handles and then dips down in this photo. Infiniti promises more details to come about the Q30 before the Frankfurt launch. At least for European examples, assembly is reportedly earmarked for the Sunderland factory in the UK.

2017 North American Car, Truck, and Utility of the Year entries announced

Over 40 vehicles will compete for the 2017 North American Car, Truck, and Utility of the Year awards. If that name looks a little strange, it's because the competition added a third category. In years past, pickup trucks, crossovers, SUVs, commercial vans, and minivans competed for the same award. That's why there were occasionally weird comparisons, like last year's competition between the Volvo XC90 and Nissan Titan XD. The new format separates pickups and commercial vans into the truck contest and CUVs, SUVs, and minivans into the utility competition. A complete list of eligible vehicles is below, but here are a few highlights. For one, the entire list of entries has a luxurious lean. Of the 43 vehicles, nearly half of them are from premium brands. There are two eligible Bentleys – the Bentayga and Mulsanne – the Rolls-Royce Dawn, Jaguar F-Pace, Audi Q7, and the Mercedes-Benz GLS-, E-, and S-Class Maybach. The performance ranks are lofty, too, with the Audi R8, Acura NSX, Alfa Romeo Giulia, Mercedes SL- and SLC-Class, Porsche 718, and F-150 Raptor. The mainstream entries are just as comprehensive. From the Chrysler Pacifica to the Chevrolet Cruze to the Fiat 124 Spider to the Mitsubishi Mirage, NACTOY has covered an enormous price range with this year's contestants. Of course, these are only the eligible vehicles. They'll need to run through three rounds of judging, starting in September at NACTOY's traditional Hell, MI, test drive. The Canadian and American journalists involved in the judging will announce this year's nine finalists – three in each category – on December 6.
