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.

Toyota, Lexus dominate KBB's Best Resale Value Awards

Toyota and Lexus stormed the 2014 Kelley Blue Book Best Resale Value Awards, winning a combined 18 categories including best brand and best luxury brand. This marks the third year in a row that both automakers have won the Brand and Luxury Brand resale value awards. In all, Toyota won 11 categories and Lexus won seven.
Honda made a good showing, as well, winning two segments (Accord Plug-In Hybrid and Civic Si) and putting one car on the top-10 Best Resale Value list (CR-V). Chevrolet did even better, winning two segments (with the V6 Camaro and the Corvette) and placing three cars on the top-10-overall list (again, the Camaro and Corvette, plus the Silverado 1500).
The other winners came from Jeep, Dodge, Infiniti, Subaru and Audi. To give you a clearer picture of the Toyota and Lexus domination, their 18 mentions represents more than half of the 34 awards (including the top-10-overall list).
