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 Motorsport cranks out Golf touring car

Just when you thought Volkswagen had done all the hot Golfs we could handle, its motorsports division has come out with an even hotter one. This racing version is built to compete in the Touringcar Racer International Series (TCR) across Europe and Asia, and certainly looks the part. Based on the production Golf hatchback we all know, the TCR competition version promises to be to circuit-based touring car racing what the Polo R WRC is to the rally stage. And that little pocket rocket has been positively dominating the World Rally Championship. Developed in conjunction with Seat's racing department and Liqui Moly Team Engstler, the Golf touring car packs the 2.0-liter turbo four from the Golf R. Only instead of 292 horsepower and 280 pound-feet of torque in the production version, it's been tuned to channel 330 hp and 302 lb-ft to the front wheels (instead of all four) through a six-speed dual-clutch transmission. It rides on 18-inch alloys fitted to a track widened by nearly a foot and a half, along with a competition-spec aero kit to keep it glued to the tarmac and a stripped-out cockpit. Though the 2015 TCR series is already under way, a pair of these racing Golfs will be entered in the upcoming round at the Red Bull Ring in Austria, before the series heads off to Singapore (in support of the F1 grand prix there) and Thailand ahead of the final round in Macau. If everything goes well, customer teams will be able to pick these up and enter them in next year's championship. Volkswagen develops new Golf for the racetrack - Concept car for customer racing, in line with new TCR regulations - Production-based touring car with 330 hp, front-wheel drive and six-speed DSG gearbox - First competitive test this weekend in Spielberg (A) Wolfsburg (09 July 2015). A new Golf for the racetrack: Volkswagen Motorsport is developing its first racing car based on the seventh generation Golf. The production-based, 330-hp concept car is assembled in accordance with TCR regulations and is intended to help Volkswagen evaluate a potential customer racing programme from the 2016 season onwards. In order to accelerate the development of the car, the new Golf will be tested under competitive conditions between now and the end of the season: as cooperation partner, the Liqui Moly Team Engstler will run two cars at the eighth round of the Touringcar Racer International Series (TCR) at the Red Bull Ring in Spielberg (A).

VW reveals updated 2016 Jetta GLI [UPDATE]

UPDATE: Volkswagen has updated its press release regarding the EA888 four-cylinder engine. Originally, it was described as the same engine as the GTI. This is not strictly the case, though. While both the GTI and GLI use the EA888 engine, the GLI's engine does not get variable valve lift. Our story has been edited to reflect this. The Volkswagen GTI's slightly more mature and conservative fraternal twin, the Jetta GLI, is getting updated for 2016 in a big way. Chief among the changes is the GLI's new engine. It's an EA888 2.0-liter, turbocharged four-cylinder, like the engine we've so thoroughly enjoyed in Autoblog's long-term GTI, although it does without variable valve lift, according to Volkswagen. It's still rated at 210 horsepower, though. Volkswagen also made some minor visual tweaks, including 18-inch "Mallory" wheels, a new front fascia, and a rear bumper that includes a diffuser and two chromed exhaust tips. There's also a new standard safety feature being offered for 2016 in the form of the Automatic Post-Collision Braking system. This is not, as we initially thought, a collision mitigation braking system, though. Basically, it only kicks in after the airbag sensors detect a crash, at which point APCB clamps down on the brakes in a bid to minimize the severity of the accident. Check out VW's full press release on the 2016 Jetta GLI, and the head up top for a look at the visual changes for this year. VOLKSWAGEN REVEALS THE 2016 JETTA GLI Jun 10, 2015 The performance version of Volkswagen's best-selling car offers new features and a sporty new look for the 2016 model year Herndon, VA — Today, Volkswagen of America unveiled the 2016 Jetta GLI, the sedan equivalent of the Golf GTI. Equipped with a specially tuned sport suspension and the same 210-horsepower, 2.0-literTSI® turbocharged and direct-injection EA888 four-cylinder engine as the Golf GTI, the GLI offers a compelling blend of value, performance and practicality. For 2016, the GLI gets a bold new look highlighted by an aggressive front fascia that incorporates a honeycomb grille and foglights, along with a new rear bumper design that has a diffuser and a pair of chrome-tipped exhausts. All 2016 Jetta GLI models have 18-inch Mallory design aluminum-alloy wheels, shod with standard all-season tires or optional summer performance tires. Inside, 2016 GLI models benefit from the new MIB 2 infotainment system that incorporates the full suite of USB and Car-Net connectivity.
