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 to display special Q60 convertible celebrating Unser at Amelia Island

Bobby Unser is one of the great American racing drivers of his generation, having won the Indianapolis 500 in 1968, '75 and '81 and belonging to the Unser racing dynasty. But he might be getting the oddest tribute of his life at the 2014 Amelia Island Concours d'Elegance. Infiniti has created a tribute to his Indy-winning 1968 car out of a Q60 Convertible (previously the G37), and he will be driving it around the event.
The Infiniti is wrapped in red, gold, black and white livery with the number 3 designed by the company's design director Alfonso Albaisa. While the connection seems dubious, Offenhauser-powered racecars are one of the featured vehicles at this year's concours, and the Japanese luxury automaker worked with the Indianapolis Motor Speedway Hall of Fame Museum to bring Unser's 1968 Eagle, which used an Offenhauser engine and flew those colors, to the show. The brand wanted a car of its own to match... no matter how outlandish it looked.
Honestly, while certainly a nice gesture, the choice still seems a bit weird. At least visitors will get the chance to see American racing royalty and his winning car. Scroll down to read Infiniti's full explanation for their effort.

"When I think about EV, we design it for China definitely, even as the first market to launch," says Infiniti President Roland Krueger. "We are discussing this internally constantly what is the right timing for Infiniti to have such vehicles." Infiniti has held back on launching an EV, focusing instead on hybrids, but says it could be "very fast" in deploying an EV once it decides to do so. Having Nissan and Renault backing Infiniti, the luxury brand is confident about its access to proven EV technology. Read more at Automotive News Europe. Thrifty car rental has added a Tesla Model S to its fleet in Canberra, Australia. Available at the Canberra Airport, it's the first luxury EV offered for rent from a mainstream rental company in Australia. Australia's capital offers a small registration discount and no stamp duty for EVs, making it a cheaper and more practical place to locate the country's first rental Tesla. Thrifty's parent company, NRMA, is calling on Australia's other states and territories to remove financial and regulatory barriers to EV technology. Read more at The Motor Report.
