2015 Spanish F1 Grand Prix makes its Deutsche mark

The first race of the European Formula One season inaugurates the second phase of the Championship. Teams overhaul their cars with the big updates they've been working on since Australia, and at the end of The Battle of Spain we find out how the positions on the field have changed. Mercedes-AMG Petronas driver Nico Rosberg brought a big update to his psychology, straight-up beating teammate Lewis Hamilton to take his first pole position of the season. Mercedes owns the front row and Ferrari maintains its status as primary challenger, Sebastian Vettel lining up in third. Williams proved it's been hitting the books to do better in class, though, Valtteri Bottas slotting into fourth. And Toro Rosso's visit to a track that rewards strong aero rewarded them with the best team grid position since the Italian Grand Prix in 2008: Carlos Sainz secured fifth, ahead of Max Verstappen in sixth. Kimi Raikkonen's bout of Saturday woes – it seems the Finn is always handicapped by lots of tiny issues – continued in Barcelona with one of his sets of prime tires getting cooked by malfunctioning tire warmers. He recovered well enough to take seventh on the grid, but he's got some strong competition ahead of him. He led three other drivers in the Continuous Issues department, Daniil Kvyat unable to wrestle his Infiniti Red Bull Racing higher than eighth, Williams driver Felipe Massa getting it wrong in Turn 3 to fall five places behind his teammate Bottas, and Daniel Ricciardo in the second Red Bull enduring another engine change and sloppy car behavior to get tenth. And while it turned out to be a steady race a little rough around the edges, the positions on the battlefield just might have changed. A little. Of the 66 laps in the race we might have seen Rosberg for three of them – maybe. The German got a smashing start, had a clear lead into Turn 1, and after that we checked in occasionally during his two pit stops and again at the checkered flag. He owned the entire weekend the way we're used to seeing his teammate do, and the cameras left him alone to run his race. No one got within seven seconds of him during the first third, and as the pit stop strategies played out that cushion grew. He finished seventeen seconds ahead of Hamilton, and 45 seconds ahead of third-placed Vettel. Hamilton, on the back foot all three days, stumbled out of the gate.

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:

The Nissan Patrol may become America's next Armada

Plausible rumors are swirling that the Nissan Patrol, the Land Cruiser rival sold outside of North America, might come to the US as a replacement for the unrelated Nissan Armada. That large SUV's future was left ambiguous after the news of the Xterra's discontinuation, as Nissan's press release ominously promised information on the Armada "at a later date" without further elaboration. That left us scratching our heads and thinking that, perhaps, it would be quietly killed off in the future. If the rumors are true, it will be. And then it will be reborn. It'll join its old platform-mate, the Infiniti QX80, on the Patrol platform. The QX abandoned its Titan-based platform in 2011, becoming the Patrol-based QX80. So you can think of the Armada as catching up, a few years late. The QX80 was refreshed last year, a mainly cosmetic nip-and-tuck. The Infiniti utilizes the 5.6-liter, 400-hp V8 and a 7-speed auto, so it's a safe bet that this powertrain will make it into the Armada version. Less likely, but plausible, would be the availability of the new powertrains intended for the Titan XD and upcoming lower-grade Titans. The massive SUV market tends to be a bit conservative, so the Cummins diesel V8 that's the sole engine in the Titan XD right now seems unlikely. The forums are abuzz with a photo of what's purported to be a leaked marketing image of the new Armada, so head to this TitanXDForum thread if you'd like to see what that's about. (Spoiler: it looks a lot like the Patrol above, minus some of the Nismo flair.) Related Video:
