Volkswagen throws a Polo-palooza with four new or upgraded models

Volkswagen unveiled a parade of new and upgraded Polo models at the 2014 Geneva Motor Show, including the Polo TSI BlueMotion, Polo TDI BlueMotion, Polo BlueGT and CrossPolo (pictured above). While they will likely never make an appearance this side of the pond, it is fun to see what European subcompact drivers will be driving later this year.
The new BlueMotion models represent the most efficient petrol and diesel options in their class, according to VW. The BlueMotion TDI offers just 73 horsepower from its diesel engine but gives the equivalent of 76 miles per gallon (US) in the EU test. The BlueMotion TSI brings a little more power with its 88-hp petrol engine and has a combined rating of 57 mpg (US) in the EU cycle.
The Polo BlueGT provides a balance of performance and economy, and for the 2014 model, it gains a 9-horsepower boost to its 1.4-liter turbocharged to give drivers 147 hp at the press of the accelerator. This year's car also has an optional Sport Select suspension with electronically controlled dampers to improve handling a bit. It's still fitted with active cylinder management to use as little gas as possible when cruising.

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.

Porsche tops JD Power APEAL study for 12th time

JD Power's 2016 Automotive Performance, Execution, and Layout (APEAL) study hasn't changed much this time around with Porsche coming in at No.1 for the 12th consecutive year, while BMW was close behind in second. Jaguar and Mercedes-Benz tied for third with Land Rover, Lexus, and Lincoln tied for No.5. The APEAL Study, according to JD Power, measures owners' level of excitement and emotional attachment across 77 parameters. Brands and cars are rated on a 1,000-point scale. The study found that new cars with modern safety features including low speed collision avoidance and blind spot monitoring have higher APEAL scores than vehicles without the features. The overall industry score increased from 798 to 801, which JD Power claims was helped by the launch of a variety of new vehicles. This year, 22 out of 30 new or redesigned cars received a higher score than the vehicle's respective segment average. Porsche is once again at the top of the list as the automaker's score increased by three points to 877. BMW outscored Jaguar to take second place with a score of 859, while the British automaker dropped three points from last year with 852 points. Volkswagen overtook Mini to become the top-ranked non-premium brand with 809 points, while the latter automaker trailed behind by one point. At the end of the scale, Smart came in at the very bottom for the second year in a row with a score of 745 points, which represents an increase of 62 points over last year. Fiat's score increased by six points to 755, but still confined the automaker to second-to-worst place for a consecutive year. Mitsubishi's score increased to 770, up from 755, to become the fourth-worst brand, while Jeep fell to third-worst with a decrease in seven points to 756. General Motors received six segment-level awards, followed by Hyundai with five, and BMW and VW earning four apiece. Surprise segment victories include the Chevrolet Camaro, which outscored the Dodge Challenger, and the Lexus RC which ranked above the BMW 4 and 3 Series.
