2015 Japanese Grand Prix is a little Mercedes, a lot of zen

Just one week on from the issues in Singapore Mercedes-AMG Petronas appeared to have solved its clamp problems and everything else. Daniil Kvyat at Infiniti Red Bull Racing took the two Free Practice scalps on Friday, but when it came time for qualifying the front of the grid looked really familiar: Mercedes' Nico Rosberg took his second pole position of the season, Lewis Hamilton next to him in second. Kvyat had a hand in that, too, the Russian getting into a big accident in Q3 when he put two wheels on the grass heading into the hairpin and veered into the tire wall so hard that he flipped. That ended qualifying before a number of drivers had a chance to improve their times, Hamilton among them. That's how Valtteri Bottas got in third for Willliams ahead of Sebastian Vettel fourth for Ferrari. Felipe Massa had the second Williams in fifth, ahead of Kimi Raikkonen in the second Ferrari. Daniel Ricciardo lined up sixth for Infiniti Red Bull Racing, a team we're going to have to enjoy watching for the rest of the season since it might not exist come 2016. Romain Grosjean gave Lotus some good news by getting into eighth, the team so strapped for cash that it couldn't get into its hospitality area, so it held press conferences outside and ate at Bernie Ecclestone's Paddock Club. Sergio Perez took ninth for Sahara Force India, and Kvyat slotted into tenth after not setting a time. The Russsian's race would begin from the pit lane once his mechanics rebuilt his car. It wouldn't be a Formula One start lately without someone at the front having clutch problems. This time it was pole man Rosberg, whose power unit got too hot and put him a few horsepower down on Hamilton through Turns 1 and 2. That's half of how Hamilton took the lead from the lights going out, and the Brit kept it throughout the race. Rosberg, however, said his race was lost when Hamilton pushed him wide through Turn 2, a move Hamilton defended. Rosberg finished almost 19 seconds behind his teammate, a gap that probably isn't fully explained by that opening incident. Hamilton's race was so uneventful that we almost never saw him on camera – that is, we saw him so much less than we usually see him when he's out in front and unpressured that Nikki Lauda said he'd ask Ecclestone why the cameras avoided him. The conspiracy theory holds that FOM was punishing Mercedes for not supplying Red Bull with engines next year.

Infiniti's variable compression engine in the 2019 QX50 is the first of its kind

The world's first variable compression ratio engine is here, in a production car. That car is the 2019 Infiniti QX50, debuting this week at the Los Angeles Auto Show. The midsize crossover has seen a refresh that has brought it an all-new platform together with new driver assist features, but it's the engine that's the centerpiece here. Nearly everything is continuously variable under the hood of the QX50 – not only the new shift-by-wire XTRONIC CVT. The new VC-Turbo gasoline engine is able to change its compression ratio from 8:1 to 14:1, or anything in between depending of the driving situation; whether there is need for top-end power or turbodiesel-like torque from low revs, or optimized fuel economy. The pistons' reach is continuously adjusted by an electric "Harmonic Drive" motor, which controls a multi-link system, affecting the top-dead-center of the pistons and changing the compression. The engine can also switch between efficiency-maximizing Atkinson cycle and regular combustion cycle, on the go – and there's both multipoint injection and gasoline direct injection employed. The result is 268 horsepower at 5,600 rpm and 280 pound-feet of torque at 4,400 rpm; good figures for a 2.0-liter four-cylinder gasoline engine with a single-scroll turbocharger. Infiniti says that the FWD version's fuel economy of 27 miles per gallon combined is 35-percent better than the previous-generation V6 engine; in AWD guise, it reaches 26 mpg, which is a 30-percent improvement. The new engine is pretty much all-aluminum, but the vaguely magical-sounding "transformative multi-link components" behind the variable compression system are made from high-carbon steel alloy. The engine's multi-link system also enables it to do away with any balancing shafts, and Infiniti compares its smoothness to a V6 rather than a regular four-cylinder. In addition to the aforementioned tech, the VC-Turbo engine has the world's first active engine mount vibration damping system to smoothen its operation even further. Related Video:

Autoblog sell-it-yourself highlight: 2013 Infiniti QX56

As Lincoln announces an all-new Navigator at this year's New York auto show, and General Motors' Arlington (Texas) plant runs 24/7 cranking out Tahoes, Yukons, and Escalades, Infiniti's big QX56/80 continues to gain fans in a great many upmarket zip codes. And its appeal – for those with an appreciation for Big Foot footprints – is obvious. Built atop Nissan's Patrol platform, the QX56 offers high levels of refinement with cubic yards of utility. Introduced by Nissan's Infiniti division in 2011, you would assume any inaugural bugs had been worked out by 2013, the QX's third model year. Power was supplied, in the press vernacular, by Nissan's proven 5.6-liter V8 producing 400 horsepower and 413 pound-feet of torque. A seven-speed automatic transmission was standard on all models, and while the additional speeds might suggest some semblance of efficiency, no one should confuse this big QX with a Toyota Prius. Our 'for sale' example, with 84,000 miles, represents above-average mileage for a 4-year old vehicle. But if those are largely highway miles in and around Madison, Mississippi, and service records are available, you shouldn't be too concerned. This is, with proper maintenance, a 200,000-mile platform, leaving you about 116,000 miles for your $37,000. And the 'ask' seems about $5,000 too dear; perhaps the seller will throw in a gas card.
