Renault's planned luxury sub-brand gets reconsidered

Renault believes there's enough Alpine love to restart that brand with its own model almost immediately. The launch of the Initiale Paris luxury brand it's been mulling, on the other hand, will be more restrained: a report in Autocar says that instead of launching with a first model based on the Mercedes E-Class architecture, Renault is going to introduce an Initiale Paris trim line on the new Clio and Espace. More accurately, that should be 're-introduce and aggressively market,' since Renault has used an Initiale Paris trim over the years since it introduced the concept car (pictured) in 1995, even as recently as the current-generation Laguna Coupe.
Other models will be added after the Clio and Espace, and when Renault can assess what kind of future the trim has, it will decide on the launch of a subsidiary brand. Company CEO Carlos Tavares said we shouldn't hang around waiting for a decision, though, declaring that establishing such a brand - if it even comes to that - "will be a job for at least my successor to worry about, not me."

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

Ten of the greatest Super Bowl car commercials of all time

With an average of over 100 million viewers each year, the Super Bowl always has advertisers bringing out the big guns. And for those among us who don't know the difference between a safety and a touchback, those commercials can be one of the most compelling aspects of the annual ritual. Car companies, in particular, have a long history of making the most of the huge Super Bowl audience by debuting some of the most memorable advertisements that have ever aired on television. So, in preparation for the new batch we'll be seeing this coming Sunday, here's a collection of our favorites from the past. 10. Audi – The Godfather When Audi created this homage to the quintessential gangster movie to promote its newest sports car, the company managed to make a commercial that was simultaneously funny, a little bit disturbing, and most importantly memorable. 9. Maserati – Strike This one might start out slow, but it delivers not only with the wicked sound of the third-generation Ghibli's engine, but with an interesting message about hubris in the auto industry as well. 8. Nissan 300ZX Twin-Turbo – Dream Directed by none other than Ridley Scott (Blade Runner, Alien), this dystopian spot has centers around a narrator who explains that in his dream the bad guys are unable to catch him despite their best efforts by way of street bikes, race cars, and supersonic jets. While the twin-turbocharged 300ZX car was certainly a performance powerhouse to be reckoned with in its day, the concept and execution of this one does come off a little bit campy now – but in a good way. Then again, it is a dream, after all. 7. General Motors – Robot This one is unique in that it's genuinely depressing on a profound level. Who would've thought that the simulated suicide of a lovable, anthropomorphic car-building robot who has fallen on hard times could be such a downer? 6. Nissan – With Dad Although the debut season of its new LMP1 racer didn't exactly turn out how the team hoped it would, there's no denying that Nissan's depiction of a strained father-and-son relationship that eventually leads to redemption (and the introduction of the 2016 Maxima) tugs at the heartstrings. 5. Volkswagen – Big Day A surprisingly poignant advert, this one might be low on dialogue but it certainly gets its message across. And just as the dramatic soundtrack begins to lull the viewer into a sense of security, our expectations are upended. 4.
