2015 Mexican Grand Prix is a lot like old times

The last time Formula One visited Mexico, in 1992, 26 cars powered by eight engine manufacturers (counting Honda and Mugen-Honda separately) lined up on the grid; it would have been nine engine makers but the Brabham-Judd cars failed to qualify. In 1992 Lewis Hamilton was seven years old, Sebastian Vettel was five, Max Verstappen was still five years away from being born. Two of the current Sky Sports F1 commentary team, Martin Brundle and Johnny Herbert, were drivers. The starting three were Nigel Mansell on pole – 39 years old, this the year he'd win his only World Championship – and Riccardo Patrese both driving Williams-Renault cars, followed by Michael Schumacher in a Benetton-Ford. Only 13 of the 26 starters would finish. The circuit is has been reworked to today's safer standards, the track surface is brand new and slippery, but the atmosphere and packed grandstands haven't changed. Nico Rosberg was another point of consistency, scoring pole position for the fourth race in a row to beat his now-World-Champion teammate Hamilton by almost two-tenths of a second. The last time Rosberg turned pole position into a victory? The Spanish Grand Prix back in May. Vettel locked up third for Ferrari, followed by the Infiniti Red Bull Racing duo of Daniil Kvyat and Daniel Ricciardo. Williams went two-up as well, Valtteri Bottas in sixth ahead of Felipe Massa in seventh. Max Verstappen turned in a great late lap to reserve eighth place, Sergio Perez did all he could in front of his home crowd to get ninth, teammate Nico Hulkenberg the caboose in the top ten. In that 1992 race the first three on the grid finished the race in the same order after Mansell dominated, and it was almost the same in 2015. If Rosberg had driven the whole season like he drove today the Driver's World Championship would still be up for grabs. He got a great start and held his line through the first corner, coming out ahead of Hamilton through the initial kinks, pulling away as soon as he got to the straight. Hamilton was never more than a few seconds behind, but every time the Brit inched closer the German found a few more tenths to keep his distance. The field got bunched up when the Safety Car came out on Lap 53 after Vettel spun and got stuck in the barriers, but Rosberg handled the restart perfectly. Both drivers made small mistakes in the last few laps while driving on the edge, but Rosberg earned a strong victory, crossing the line two seconds ahead of his teammate.

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:

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.
