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.

Infiniti teases Qs Inspiration electrified sedan concept for Auto Shanghai

Infiniti has the third installment of its Q concept lineup ready for Auto Shanghai in a couple of weeks. The 2018 Detroit Auto Show saw the Q Inspiration concept, a slinky pearlescent sports sedan. This year's Detroit show welcomed the QX Inspiration concept, an ivory electric crossover that previewed a future product. The Shanghai debut blends the two with the Qs Inspiration concept, "an electrified sports sedan for the future," that previews a forthcoming product. The Qs Inspiration appears to pick up where the 2018 Q Inspiration left off. We noted last year's show car didn't have visible tailpipes, and we suspected an electric powertrain. That wasn't the case — Infiniti said the brand's VC-Turbo technology powered the four-door. This new Qs Inspiration is built on an "all-new flexible architecture developed specifically for electrified powertrains." That's a curious distinction if by electrified Infiniti means an electrically assisted ICE. If a car needs all the paraphernalia of an ICE drivetrain, where's the electric leap? It must be somewhere, because Infiniti says the Qs Inspiration is as groundbreaking as the Q45 sedan that birthed the brand in 1989. Company boss Christian Meunier said, "Electrification creates a range of new possibilities for sedans," the concept "letting us imagine how this type of car could be reinvigorated and adapted to fit the changing needs and tastes of drivers." The teaser tells us nothing but to expect more white. There will be an "electrified form language" outside, a "minimalist cabin" inside. The dual-zone interior contains a "clutter-free cockpit ... to engage the driver, and a relaxed passenger zone that make the most of the generous interior space." Naturally, there'll be more Japanese "artistry and craftsmanship" than you can process in one sitting. Stay tuned April 16 for the reveal.

Red Bull keeps 2015 RB11 F1 challenger under wraps [UPDATE]

UPDATE: A previous version of this post suggested that Daniil Kvyat drove for Red Bull last year, when he actually drove for its affiliate team Toro Rosso. The text below has been updated with the correct information. This season will be one of new beginnings for Red Bull Racing. It's the first time in three years that it's not returning to the Formula One grid as defending champions, and without a world champion at the helm. But return it will to fight to regain its title, and this is the car with which it intends to do so. Revealed ahead of the season's first test session in Jerez this weekend, the new RB11 is wearing a bold camouflage "testing livery" of the type we're more accustomed to seeing on road-going prototype than on a racing car. Expect it to be replaced by the familiar blue, red and yellow by the time the season kicks off in Melbourne next month. Though the camouflage may keep certain aero developments disguised (if not altogether hidden) from the prying eyes of its rivals, the sloping nose mandated by the new regulations is plain to see. Otherwise the new RB11 is likely more of an evolution rather than a revolutionary clean-sheet redesign over the RB10 that returning hot-shoe Daniel Ricciardo drove last year, to be joined this season by Daniil Kvyat, who's been promoted from Toro Rosso to replace departing four-time champion Sebastian Vettel. Whether they can succeed, however, will largely depend on the engine. Red Bull has emerged as the primary partner for engine supplier Renault (sister company to the team's title sponsor Infiniti). In fact, after Lotus switched to Mercedes (and assuming Caterham doesn't make it back to the grid), Red Bull and its sister team Toro Rosso will be the only teams running Renault engines this season. The team says it has worked closer than ever with the French automaker to develop the Renault power unit, but chances are slim that they'll be able to catch up to Mercedes given the restrictions on engine development. If anyone can catch the Silver Arrows, though, it'll surely be Red Bull – the only other team to win a grand prix last season. THE RB11 REVEALED After an intensely busy off-season, Infiniti Red Bull's Racing's 2015 Formula One car, the RB11, has hit the track and begun testing at the Circuito de Jerez in Spain ahead of the new season.
