Infiniti QX50 concept previews production model with variable compression engine

Infiniti revealed its QX50 concept ahead of its official debut at the Detroit Auto Show, and despite the concept title, it looks pretty much production-ready. The company calls the crossover "an evolution of the QX Sport Inspiration" concept, and that's certainly accurate. Side-by-side, the QX Sport, which we already figured was previewing a new QX50, and this concept look nearly identical. The primary changes are bumpers and side skirts that feature the obligatory aluminum trim to look like skid plates, and simple black plastic fender flares. The overall result is a crossover that is pleasant but not exactly exciting that bridges the gap between the small and swoopy QX30 and the large QX60. The plain wrapper hides plenty of impressive technology, though. Under the hood is Infiniti's fascinating variable-compression turbocharged engine. It's a 2.0-liter inline-four that can alter its compression ratio to anything between 8:1 and 14:1. The result is an engine that produces an estimated 268 horsepower and 288 lb-ft of torque. Infiniti says the four-cylinder should be about 27-percent more efficient than a comparable V6. In addition, while the company says this concept just shows a potential application of the engine, it's safe to say that you can expect it in the production model. With the new engine, the QX50 will also switch from to a front-drive platform, with all-wheel drive definitely an option or possibly standard; the current QX50 is based on the aging rear-drive FM platform used on other Infinitis and the Nissan 370Z. The other new tech buried in the QX50 concept's body is what Infiniti calls the "first production-ready incarnation" of its ProPilot semi-autonomous technology. The company doesn't go into great detail about what it will do except for handling stop-and-go highway traffic. We would hazard a guess that the system is functionally the same as the one introduced on the Nissan Serena minivan in Japan. It goes by the same name and can handle stop-and-go traffic, as well as maintain the car's lane position and distance behind other cars. It's another safe bet that we'll see this system in the production model. Other details about the car, such as the interior, have yet to be revealed. We're sure to see it as well as other information about the QX50's technology when it makes its full debut in Detroit. Related Video:

2022 Infiniti QX80 Interior Review | Refreshed, but still behind

You might assume the 2022 Infiniti QX80’s interior is filled with outdated technology from when it launched here about 10 years ago, but thatÂ’s not entirely true. You see, despite the rest of the car carrying over from the previous model year, the 2022 model year QX80 enjoys a refreshed interior. While this interior is updated, thereÂ’s no need to get overly excited. Nissan put the Armada through a mid-cycle refresh last year, and the QX80 essentially cribs all of its new bits directly from the Nissan. WeÂ’ve already tested the Armada, so we had an idea about what to expect when the refreshed QX80 landed at our doorstep. Thankfully, for InfinitiÂ’s sake, the ArmadaÂ’s new interior is nice enough that it's largely acceptable in the more luxurious QX80. It features a new, high-res touchscreen, flashy plastics, a simple layout and vital tech like a wireless phone charger, USB-C port and wireless Apple CarPlay — unfortunately, Android Auto remains a wired-only affair. The new look of this tall and vast center stack doesnÂ’t jive perfectly with the QX80Â’s flowy, rounded interior design, but thatÂ’s what you get when part of the interior is updated and the rest is left to carryover. Straight, strong lines dominate the center stack, complemented by rectangular vents. Meanwhile, rounded wood trim flows out of this brutalist center stack in a jarring manner that makes the interior look like two different designers worked on it separately, then had their work combined.  Functionally, the new parts of the interior are just fine. The new single touchscreen and its supporting user interface is a welcome update over the old dual-screen infotainment system that's still found in other Infinitis (it had only just received that system for 2020). Its large, width-oriented and mounted higher for easy viewing, plus the presence of supporting physical knobs and buttons make vital controls easy to use and adjust. The odd storage compartment in the dash houses the wireless phone charger, and the 12V outlet is hidden in there alongside it. We enjoyed the presence of a wireless phone charger, but it didnÂ’t charge our phones quickly, and the phoneÂ’s movement on the mat would sometimes cause it to stop charging altogether. Surprisingly, the QX80 is fitted with a camera rearview mirror, which was a nice surprise to see.

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.
