A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

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.

2017 Infiniti Q60 3.0t Sport starts at $49,205

Infiniti announced pricing Wednesday for the 2017 Q60 3.0t Sport. The 300-horsepower Q60 3.0t Sport starts at $49,204, while the all-wheel-drive variant starts at $51,205. The new models slot snugly in between the Q60 3.0t Premium AWD and the Q60 Red Sport 400. The Q60 3.0t Sport's price isn't the only thing that makes it the middle child, as the 3.0-liter twin-turbo V6's output is in the middle, as well. The base Q60 2.0t is fitted with a turbocharged inline-four that generates 208 horsepower, while the range-topping Q60 Red Sport 400's 3.0-liter twin-turbo V6 puts out 400 horsepower. The Q60 3.0t Sport makes an even 300 horsepower, not enough to crowd the Q60 Red Sport, but a large increase over the inline-four motor. In terms of features, the Q60 3.0t Sport trims gets a lot of the same components as the high-end models, including the sport brakes, Dynamic Digital Suspension, 19-inch aluminum alloy wheels, carbon-fiber trim on the inside, and more. The two models will go on sale next month and bring the total of available Q60 models up to 10. This content is hosted by a third party. To view it, please update your privacy preferences.
