VW decides against active-cooling system for e-Golf lithium battery

When the 2015 VW e-Golf was introduced at the LA Auto Show last year, VW said it would come with a water-cooled battery. During the Detroit Auto Show, when the car was trotted out again, VW released a new press release that stripped out the "water-cooled" language, but this change went unnoticed. During a recent VW event in Germany, a friend from Green Car Reports realized that the battery on display did not seem to have any water-cooling mechanisms. That set us off on a bit of a sleuthing and we have now learned that VW is not going to include any active cooling in the upcoming e-Golf. In fact, the company is entirely confident that this car - because of what it's designed to do - doesn't need it. "The need for a cooling system wasn't there" - VW's Darryll Harrison VW has been working on an electrified Golf for ages now, and so changes to the plan are to be expected. But battery cooling is vitally important not just to keep the car operating properly but because when things get too hot, there can be serious public relations problems. Nissan began testing a new battery chemistry for the Leaf in 2013 after an uproar from warm-weather EV drivers in Arizona who were experiencing worse-than-expected battery performance. The Leaf has always used an air-cooled battery, which is another way to say that there is no active cooling system (more details here). Tesla CEO Elon Musk once said this approach is "primitive." So, why is VW following the same path? We asked Darryll Harrison, VW US's manager of brand public relations west, for more information, and he told AutoblogGreen that VW engineers discovered through a lot of testing of the Golf Mk6 EV prototypes, that battery performance was not impacted by temperatures when using the right battery chemistry. That chemistry, it turns out, is lithium nickel manganese cobalt oxide (NMC) in cells from Panasonic. These cells had "the lowest self-warming tendency and the lowest memory effect of all cells tested," Harrison said. He added that VW engineers tested the NMC cells in places like Death Valley and Arizona and found they didn't warm very quickly either through operation, charging (including during fast charging) or through high ambient temps. "The need for a cooling system wasn't there," Harrison said.

Volkswagen unveils sportier Passat Performance Concept ahead of Detroit debut

Ahead of its official unveiling at next week's Detroit Auto Show, Volkswagen has released some preliminary details and images of its Passat Performance Concept - a car that, as its name suggests, adds a little more spice to the automaker's midsize sedan formula. VW makes no mention of any production intent for this road-ready-looking sedan, simply stating that the Performance Concept is a way to "explore this practical four-door's sportier side."
It certainly doesn't look too sporty, the only visual upgrades being larger 19-inch wheels, dual exhaust, bi-xenon headlamps with VW's Advanced Front Lighting system, LED taillmaps and carbon-look mirror caps. Inside, there are carbon interior accents and two-tone leather upholstery. But no matter, the real upgrades for this mightier Passat are found below the sheetmetal.
Powering the Performance Concept is a 1.8-liter turbocharged four-cylinder engine, churning out 250 horsepower and sending its grunt to the ground via a six-speed automatic transmission. For reference, that's 80 more horsepower than the Passat's base 2.5-liter inline-five, but 20 horsepower less than the potent 3.6-liter VR6. As for other performance upgrades, Volkswagen has fitted the car with a lowered sport suspension and revamped electronic steering, which should indeed add a bit more dynamic feedback to the already nice-driving sedan.

Volkswagen Cross Up! aimed at rugged lifestyle folks, complete with plastic cladding

If you thought there was nothing wrong with the Volkswagen Up! that a little body cladding wouldn't fix, you're in luck. VW has officially pulled the wraps off the production version of the Cross Up!, and its wheel arches and rocker panels are full of the black plastic cladding you've been yearning for.
In addition to the "particularly rugged design and tough, lifestyle qualities" that the cladding exudes, VeeDub has also seen fit to put its Cross Up! on a new set of 16-inch alloy wheels clad in 185/50-series tires. Inside, there are new kick plates to go along with a dash pad that can be had in red, black or silver.
All that cladding must equal additional off-road readiness, right? Well, sure... just so long as you're fine with the same 75-horsepower three-cylinder engine that all other Up! models also feature, along with a five-speed manual transmission sending power to the front wheels, again, just like all other Up! models. The Cross Up! appears to have a taller ride height than other models, but we haven't been able to find out what - if any - changes have been made.
