Infiniti to get Leaf-based electric sedan after all

Infiniti suffered a huge blow a few weeks ago when CEO Johan de Nysschen jumped ship after two years on the job to take the helm at Cadillac. As boss, he spearheaded change within the Japanese luxury brand and was among the biggest champions of the Q50 Eau Rouge. However, the company is far from sunk. Plans put in place prior to de Nysschen leaving are still on the table, according to Nissan product planner Andy Palmer to Automotive News, and that could mean a rosy future for the once AWOL LE sedan (pictured above) and other models.
Back in 2012, Infiniti promised that it would have the LE on the market as a premium electric sedan by 2014. It was supposed to share the battery pack with the Nissan Leaf but with a more powerful, 134-horsepower motor. But have you seen one on the road recently? The luxury EV was eventually shelved, but de Nysschen pledged the idea wasn't dead. Maybe now is a better time for it. According to Automotive News, the LE is rescheduled to launch in 2017 or 2018. The latest version would use the Leaf platform but with a more potent, next-gen battery to give it a range over 90 miles.
Of course, the LE isn't the only thing on the way from Infiniti; it also appears to be planning a two-pronged approach for small cars. Palmer recently tweeted that the company would build the forthcoming Q30 hatchback and QX30 crossover in the UK in 2015. Additionally, the automaker is firing up a new joint venture factory in Mexico with Mercedes-Benz; building compact models there starting in 2017. According Automotive News, the Mexican-built models will be more US-focused while the UK-built ones will appeal more to Europeans.

Q50 Eau Rouge to kick off series of performance Infinitis

Infiniti is desperate to position itself as a brand for performance enthusiast. It's tried to create that impression by attaching its name to the Red Bull Racing team, by sprucing up the G37 Coupe and G37 Convertible as part of its lack-luster Infiniti Performance Line, and by bringing Sebastian Vettel on board to create a special edition FX crossover. But the Japanese luxury brand knows it's going to need something more comprehensive if it's going to go up against BMW and its M models, Mercedes and its AMGs, or Audi and its Quattro GmbH-tuned RS range.
That's why the Q50 Eau Rouge concept unveiled just last week at the Detroit Auto Show was so important to the marque. But Infiniti has more in store than just a concept. Nissan desires to put the Q50 Eau Rouge - named after the notoriously challenging turn at the Spa Francorchamps circuit in Belgium - into production with a 500-horsepower engine. But in speaking to Automotive News, Infiniti chief Johan de Nysschen hinted at more good news to come.
That could include a performance version of a new flagship sedan Infiniti is said to be working on, positioned above the current Q70 to fill the void left by the discontinued Q45 that capped the brand's range before it shifted its entire naming scheme behind it. The flagship sedan would need some serious muscle to challenge the likes of the Mercedes S63 AMG and Audi S8, but Infiniti seems bent on getting there. To cap it all off, Infiniti has long been rumored to be working on a halo sports car. Whether they'll all carry the Eau Rouge name, the IPL badge or some sort of other designator remains to be seen, but we'll enjoy seeing this development progress.

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.
