Ex-Fiat exec: VW diesel scandal will hurt plug-in hybrids

It doesn't sound right at first blush, but former Fiat executive and noted diesel-powertrain expert Rinaldo Rinolfi thinks that plug-in hybrid sales may be more impacted by the VW diesel-emissions scandal than diesel sales. Rinolfi, who worked for Fiat for 40 years, told Automotive News Europe, said that the Euro 6 emissions rules that went into effect in 2015 have already increased diesel-engine production costs enough to raise prices and ultimately flatten demand. By the end of the decade, diesel-vehicle sales will settle in at a 40-percent market share of new European vehicles, and that was going to happen with or without the scandal. "Every carmaker has found ways to achieve fuel consumption and emissions results that have progressively diverged from the real driving conditions." - Rinaldo Rinolfi Makers of plug-in hybrids have more to lose, though, because every PHEV maker has figured out a way to keep emissions figures artificially low, Rinolfi said. Under New European Driving Cycle (NEDC) standards, PHEVs can be tested part of the time with the electric motor in action, meaning emissions get driven down to 30 percent to 40 percent less than real-world figures. With the VW scandal pushing regulators to use real-world figures, those PHEV emissions numbers are expected to rise substantially. To a lesser extent, hybrid emissions figures are also tested as artificially low. "Over the years, even without defeat devices, every carmaker has found ways to achieve fuel consumption and emissions results that have progressively diverged from the real driving conditions the customer experiences," Rinolfi said in the Automotive News Europe interview. Rinolfi is a little sunnier about compressed natural gas (CNG) vehicles, estimating that CNG emissions are as much as 25 percent lower compared to conventional vehicles. As for battery-electrics, he's not so optimistic, estimating that there needs to be at least a tenfold improvement in energy efficiency for EVs to be truly competitive with conventional vehicles. "I've been waiting for a true breakthrough for the past 25 years, but I've not seen it yet," Rinolfi said about EVs in the Automotive News Europe interview.

2015 VW Golf SportWagen priced from $21,395*

Now known as the Volkswagen Golf SportWagen in the US, the long-roof version of the platform gets larger for its new generation in 2015, but it also sheds up to 137 pounds and cuts some money off the price of some models. The base now begins at $21,395, plus $820 destination on all versions, when they arrive at dealers in April. Volkswagen claims that with all of the extra standard content, buyers actually save $700 compared to the previous-gen Jetta SportWagen, despite its lower $20,995 starting price. The S trim is the least expensive model and comes with a five-speed manual and 1.8-liter turbocharged four-cylinder making 170 horsepower. Paying an extra $1,100 adds a six-speed automatic. The SE for $26,995 gets the auto as standard and also includes a panoramic sunroof, front foglights, push-button start and a rearview camera. The top SEL for $29,345 further features chrome roof rails, navigation, a 12-way power driver's seat and more. In addition to the gas engine, buyers can choose the 2.0-liter TDI with 150 hp and 236 pound-feet of torque, and VW quotes EPA estimates of up to 43 miles per gallon highway fuel economy for it. All of the trims with the oil burner come with a six-speed manual, but a six-speed DSG is a $1,100 extra. The base TDI S trim starts at $24,595, which is nearly $2,000 less than the last-gen Jetta SportWagen with a diesel, and buyers also get standard push-button start and a rearview camera. The SE and SEL trims offer similar upgrades as their gasoline counterparts and ring up for $27,995 and $30,345, respectively. Of course, many buyers want extra tech for their cars, and VW is offering two packages of options for the SE and SEL trims with either engine. One adds collision warning, automatic post-collision braking and front and rear parking sensors for $695. The Lighting Package includes adaptive Bi-Xenon headlights, LED running lights and LED interior lighting for $995. VOLKSWAGEN ANNOUNCES PRICING OF 2015 GOLF SPORTWAGEN ? New TDI® S model reduces base Clean Diesel pricing by almost $2,000 ? Newly available driver assistance technology includes Forward Collision Warning and Automatic Post-Collision Braking System ? Larger interior than outgoing Jetta SportWagen rivals compact SUVs for size ? Car will be offered with 1.8-liter turbocharged TSI® gasoline and 2.0-liter TDI Clean Diesel engines ?

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.
