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.

2016 Infiniti Q50 gets 2.0L turbo four

After adding a US-built, 2.0-liter, turbocharged four-cylinder to the European and Chinese-market Q50, Infiniti will finally add this engine to the US-spec car. Official details are exceedingly scarce, with the company only saying the 2.0-liter will hit dealers this winter and that additional info will be made available this fall. We can, however, make a few safe assumptions based on the engine's output in Europe. According to our previous story on the Decherd, TN-built engine, the turbocharged mill will offer up 211 horsepower and 236 pound-feet of torque. That plants it squarely between the outputs of the 2.0-liter turbo in the BMW 320i and 328i, though it's down on power compared to the engines offered in the Cadillac ATS, Mercedes-Benz C-Class, and upcoming Lexus IS 200t. There's also a 100-plus-horsepower gap between the Q50's two gas-only engines. Considering all of these things, not to mention Infiniti's reluctance to reveal official specs, it seems safe to wager that the Japanese brand will find a way to squeeze more power out of the current 2.0-liter turbo. That'd allow the Q50 to better challenge the competition's entry-level offerings while bringing the starting price point down from the roughly $38,000 it sits at now. That's grain-of-salt conjecture on our part, though, so caveat emptor. Expect to hear more on the Q50's new engine later this year. Until then, scroll down for the official press release cover all of Infiniti's 2016 updates. INFINITI – WHAT'S NEW FOR 2016 For 2016, the Infiniti lineup in the United States expands once again, literally, with a new longer, roomier Infiniti QX50 premium crossover. With its wheelbase extended 3.2-inches, the 2016 QX50 offers greatly increased rear passenger room, as well as additional cargo space. It also features new exterior styling. There are additional changes in store for 2016, starting with the addition of a new 2.0-liter turbo 4-cylinder engine for the Infiniti Q50 sports sedan available in the winter of 2016. Other Infiniti Q50 enhancements will be announced at the North American International Auto Show in January. In addition, revisions to the Infiniti QX60 luxury crossover will be announced at that time. The Infiniti QX80 full-size SUV keeps it fresh for 2016 with a new Signature Edition, which includes Driver Assistance and Split Bench packages, Saddle Tan high-contrast interior, bodyside moldings and chrome mirror caps. The QX80 Special Edition is limited to just 1,000 units.

IIHS: High numbers of drivers treat partially automated cars as fully self-driving

WASHINGTON — Drivers using advanced driver assistance systems like Tesla Autopilot or General Motors Super Cruise often treat their vehicles as fully self-driving despite warnings, a new study has found. The Insurance Institute for Highway Safety (IIHS), an industry funded group that prods automakers to make safer vehicles, said on Tuesday a survey found regular users of Super Cruise, Nissan/Infiniti ProPILOT Assist and Tesla Autopilot "said they were more likely to perform non-driving-related activities like eating or texting while using their partial automation systems than while driving unassisted." The IIHS study of 600 active users found 53% of Super Cruise, 42% of Autopilot and 12% of ProPILOT Assist owners "said that they were comfortable treating their vehicles as fully self-driving." About 40% of users of Autopilot and Super Cruise — two systems with lockout features for failing to pay attention — reported systems had at some point switched off while they were driving and would not reactivate. "The big-picture message here is that the early adopters of these systems still have a poor understanding of the technologyÂ’s limits," said IIHS President David Harkey. The study comes as the National Highway Traffic Safety Administration (NHTSA) is scrutinizing Autopilot crashes. Since 2016, the NHTSA has opened 37 special investigations involving 18 deaths in crashes involving Tesla vehicles and where systems like Autopilot were suspected of use. Tesla did not respond to requests for comment. Tesla says Autopilot does not make vehicles autonomous and is intended for use with a fully attentive driver who is prepared to take over. GM, which in August said owners could use Super Cruise on 400,000 miles (643,740 km) of North American roads and plans to offer Super Cruise on 22 models by the end of 2023, did not immediately comment. IIHS said advertisements for Super Cruise focus on hands-free capabilities while Autopilot evokes the name used in passenger airplanes and "implies TeslaÂ’s system is more capable than it really is." IIHS in contrast noted ProPILOT Assist "suggests that itÂ’s an assistance feature, rather than a replacement for the driver." NHTSA and automakers say none of the systems make vehicles autonomous. Nissan said its name "is clearly communicating ProPILOT Assist as a system to aid the driver, and it requires hands-on operation.
