2015 Volkswagen Jetta TDI

Volkswagen calls its 2015 Jetta "refined, redesigned," and countless man-hours have gone into its re-engineering, but you'd need to crawl all over the car, unbolt most of the body, drive it or spend some time on VW's website to fathom the changes. That's why we wrote, "2015 Volkswagen Jetta is new, we promise," when we first saw the car in New York last April. While we wait for a sweeping next-generation overhaul to come, the marquee elements for now are the new structure underneath designed to win an IIHS Top Safety Pick+ rating, fuel economy increases and a heavily reworked 2.0 TDI diesel engine. Plus, there's ornamental detailing around the body and updated interior, and the revamped trim package and accessories matrix promises to provide more value. That makes it a better buy than the 2014 model, assuming it can find buyers ready to appreciate the subtleties. Outside, improved aerodynamic prowess is the primary goal, and almost all of the visual refresh works to further that aim. A new grille with three cross fins sits atop a slipperier bumper and air intakes. On models with the 1.8T gas engine and new 2.0 TDI diesel, the grille is fitted with a shutter to decrease drag and, on the diesel, speed up the engine warming. There are sleeker rain gutters inside the A-pillars and paneling under the body by the rear axles. Attending to airflow in back is an altered decklid reshaped with an integrated spoiler. Among the other changes are optional adaptive bi-Xenon headlights lined with 15 LED running lights and a chrome strip of brightwork. New fog lights are set in the flanks of the lower lip, and LED taillights can be had on the GLI and Hybrid models, with a tweaked VW logo sitting in between. The illuminating upgrades continue inside with ambient lighting and a crisper dash cluster display. Those cabin changes are joined by an optional "tunnel" theme for the gauges, a new steering wheel design with piano black accents and chrome, redesigned vent controls and new fabric options. Changes to the front substructure from the bumper to the front doors, and strengthened A-pillars combined to win the 2015 sedan a Top Safety Pick+ rating from the Insurance Institute for Highway Safety. We're here to focus on the diesel model, and the updated EA288 2.0 TDI engine and its modular packaging is the most visceral highlight for 2015, inserting new numbers on every line of the spec sheet compared to its predecessor, save for cylinder bore spacing.

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.

2023 New York Auto Show Live Updates: Hyundai's surprise, Nissan's super stand, '24 Wrangler

The 2023 New York International Auto Show shifts into high gear Wednesday, April 5, and our reporters are already in the city, with events unfolding even as we speak. We'll being seeing cars in person, interviewing automaker insiders and snapping photos of vehicles and all the other oddities that pop up at an event like this and we'll be giving you live updates and color from the show floor along the way.  Ram, Hyundai, Subaru, Kia, VW and Jeep are all expected to show something new this week, and other automakers are known to be hosting off-site events that may produce news — expected or otherwise. Genesis has already revealed its GV80 Coupe, for example, along with the fact that it has been confirmed as a production model. And we're just getting started.  Read on below for our observations from the show floor and points beyond: This content is hosted by a third party. To view it, please update your privacy preferences.
