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.

Lotus could build production versions of Renault Alpine, Infiniti Emerg-E

As with one of those blockbuster three-team NBA trades that actually improves the fortunes of every team involved, a report in Autocar indicates that Renault, Infiniti and Lotus are in talks that could benefit both manufacturers and enthusiasts. Renault is considering a production version of the devil-in-blue Alpine A110-50 concept but has said that it "probably needs more than the Renault-Nissan Alliance on its own." Enter Lotus, whose Evora platform could supply the running bits for the mid-engined Alpine revival.
That same Evora platform, in range-extended 414E concept form, is the basis for the Infiniti Emerg-E concept. Even though a decision hasn't been made on the Emerg-E's production, it is still being developed and the company has admitted that it "could be built in Britain." For its part, Lotus has said that it's ahead of schedule on the Evora 414E, with its 408 horsepower, 738 pound-feet of torque and 30-mile electric range. Development funds from both Renault and Infiniti could help make all three cars a closer possibility.

Junkyard Gem: 1999 Infiniti G20t

When Honda began making zooted-up Civics with big engines and different bodywork in the late 1980s, selling them as Acura Integras in North America and raking in many dollars, Nissan took note. For the 1990 model year and the launch of the Infiniti brand, the luxed-out version of the Euro-market Nissan Primera sedan got Infiniti G20 badging and went on sale over here. After a two-year hiatus in 1997 and 1998, the all-new G20 made its debut for the 1999 model year, and that's what we've got here: a fully equipped Touring version with 5-speed manual transmission, spotted in a Denver boneyard. The G20 Touring got leather seats, a limited-slip differential, and a racy-looking spoiler. Sure looks speedy, though the G20t was less about performance than it was about comfort. G20t buyers got these hep-looking 16" wheels. With just 140 horses from its SR20DE engine (which also went into the quicker Sentra-based machinery of 1999), the G20t wouldn't be beating many of its competitors in drag races.  With the 5-speed manual transmission, though, the stock G20t became tolerably fun. Plenty of G20 owners added more power and threw connecting rods enjoyed sport-compact domination during the early 20th century. This one seems pretty tired, but hints of the original snazziness of its interior remain. The good old packing-tape taillight repair. This content is hosted by a third party.
