Race Recap: Abu Dhabi GP is reversals, luck, leanness and last dances

We weren't sure if Alter Ego Nico Rosberg, the one who flew into Brazil and showed Mercedes AMG Petronas teammate Lewis Hamilton that he knew also knew how to grab an entire race weekend by the scruff of the neck, arrived in Abu Dhabi. In both Friday practice sessions Hamilton showed Rosberg the way. Then on Saturday, Alter Ego Rosberg took over, taking the last Free Practice session and then pole position by a whopping four-tenths of a second over Hamilton. Thanks to the gimmicky and soon-to-be-obliterated spectre of double points, if Rosberg won the race and Hamilton finished lower than second, the World Championship would remain in German hands. Behind Hamilton came the Williams duo, again, with Valtteri Bottas ahead of Felipe Massa. Daniil Kvyat did swell to put his Toro Rosso in fifth, Jenson Button was just as swell getting his McLaren into sixth. Kimi Raikkonen outqualified his Ferrari teammate Fernando Alonso for the third time this year, the pair taking seventh and eighth on the grid. Kevin Magnussen lined the second McLaren up in ninth, Jean-Eric Vergne making the top ten for Toro Rosso in his last race for the team. To be clear, that was the final grid for race: Daniel Ricciardo and Sebastian Vettel had both qualified in the top ten but were sent to the back of the grid when their Infiniti Red Bull Racing front wings were deemed illegal. They'd start from the pit lane, which was still ahead of Romain Grosjean in the Lotus, who took so many penalties for new engine components that he started the race in Turkey. At lights-out on Sunday, well, it was pretty much lights out. That's when Hamilton got the start of the year, bolting off the line so quickly it didn't take him 100 meters to get in front of Rosberg. The Brit took Turn 1 in the lead, then laid more than a second into the German on the first lap. Rosberg kept close, about 2.5 seconds back, but it was Hamilton's race to lose and everyone knew it; barring a reliability issue or the kind of driving mistake Hamilton hasn't made all year, Britain would have its fourth double world champion. Rosberg was left asking his engineer what kind of strategy they might use to claim first place. That reliability issue did come, but it struck Rosberg on Lap 26 when his entire Energy Recovery System failed, robbing him of 160 horsepower and taxing his brakes.

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:

2015 Infiniti QX80 gets a minor refresh, fancy new trim

Infiniti revealed an ever-so-slightly refreshed QX80 alongside its Q70 luxury sedan this morning in New York. The biggest news for the brand's fullsize SUV is the addition of a range-topping trim level, unimaginatively dubbed the QX80 Limited.
The Big 80 sports a couple of styling tweaks in an effort to bring its appearance more in line with the brand's current design language. The "double-arch" grille with mesh inserts we first viewed on the Q50 now adorns the front fascia, and the head and taillights have gone full-LED. Still, it's hard to call this SUV anything but ugly. It's bulbous and almost brutish, which aren't generally words you want to have to use when talking about any kind of luxury vehicle.
There aren't many updates inside or to the drivetrain, either. Like the Q70, Infiniti has added a couple of new tech features, such as its Predictive Forward Collision Warning system and High Beam Assist. Although it's getting a bit long in the tooth, the interior remains nice, with lots of wood and leather all around. The SUV continues to use a 5.6-liter V8, which produces 400 horsepower and 413 pound-feet of torque, mated to a seven-speed automatic transmission.
