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:

2025 Infiniti QX60 ditches V6, gains VC-turbo

The 2025 Infiniti QX60 will ditch its long-running VQ-series V6 in favor of Infiniti's variable-compression turbo engine. There's news beyond the powertrain overhaul too as the 2025 model sees some equipment upgrades and a new Black Edition. The blackout package is not new to Infiniti, but it's a first for this QX60. Let's start under the hood.  With 268 horsepower and 286 pound-feet of torque, the VC-T four-cylinder gives up 22 horses in exchange for 16 lb-ft of torque. That's a bit of a side-grade rather than an upgrade, perhaps, but the new four-cylinder delivers better fuel economy, making the whole pill a bit easier to swallow. The FWD model will return 22 mpg city, 28 mpg highway and 24 mpg combined, the EPA says (vs. 21/26/23 with the V6) while the AWD model improves to 22 mpg city, 27 mpg highway and 24 mpg combined (from 20/25/22). That's a 10% bump in city mileage vs. the V6 — not earth-shattering, but not bad, either. And we know what you're thinking, but fear not; this doesn't mean the QX60 is now saddled with a CVT. The nine-speed auto carries over and yes, it can still pull 6,000 pounds with AWD and the tow package.  For 2025, all QX60s get a new fob with an optional automatic lock/unlock feature. The Black Edition (see the gallery above) will be available on Luxe models and includes the gloss black wheels, grille surround, roof rails and exterior badges; illuminated front and rear kickplates; "radiant" grille badge; welcome lighting and a black headliner. The base price of the Pure model is up just $550 from 2024, however the FWD variant of the Autograph has been dropped, making it $4,300 more expensive to get into the trim. However, the AWD variant only increases by $50. Here's pricing information for the entire 2025 QX60 lineup with front-wheel drive (including destination). AWD is $2,000 more on every trim but the Autograph, which bakes it in as standard equipment for 2025.  Pure: $51,550 Luxe: $58,150 Sensory: $60,450 Autograph: $67,500 Related Video:  2023 Nissan Pathfinder Rock Creek walkaround This content is hosted by a third party.

Race recap: 2015 British Grand Prix is a testament to timing

In front of his home crowd, Lewis Hamilton actually had to work for pole position at the British Formula One Grand Prix. The World Champion couldn't get on top of the setup for his Mercedes-AMG Petronas on Friday, lapping behind teammate Nico Rosberg and the two Ferraris. Come Saturday, after a few alterations and a whole lot of wing to clamp down on understeer, Hamilton returned to his regular program at the front, taking pole position by just over a tenth of a second from his teammate. Williams, thought to be headed for another stretch in the weeds a few races ago, showed its best strength all year. The Grove team got both cars on the second row and in front of the Ferraris, Felipe Massa qualifying ahead of teammate Valtteri Bottas, but they were eight and nine tenths behind the Mercedes'. Kimi Raikkonen out-qualified Ferrari teammate Sebastian Vettel for the second time this year, and only the first time in a straight-up battle with two healthy cars. But more than a second behind the two cars at the front, and with two nearly-impossible-to-pass Williams' in front, neither the Finn nor the German is happy with where they are. Daniil Kvyat claimed seventh, his side of the garage at Infiniti Red Bull Racing having got through the weekend to that point without a single complaint about their Renault power unit. Carlos Sainz, Jr. put a single Toro Rosso inside the top ten in eighth position, ahead of Nico Hulkenberg who did the same for Sahara Force India by slotting in ninth. The second Infiniti Red Bull driven by Daniel Ricciardo did have an unspecified engine complaint – his car kept "bleeding power" on the straights – but even so he managed to qualify tenth with his second-fastest lap. The stewards deleted his best lap because he ran three centimeters outside the track limits at Copse, an infraction that stung a few other drivers as well. Up in front, what would sting the Mercedes-AMG Petronas drivers the most was the start. That's when a dearth of grip struck both Hamilton and Rosberg, allowing Massa and Bottas to slide right up the middle between them and take the first two places. The leapfrogging was so surprising that it looked like the Mercedes drivers were giving the Williams drivers a head start. They diced through the first corners, Hamilton sliding past Bottas into second place halfway through the lap. And then the safety car reported for duty.
