Volvo leads and Mini fails in JD Power's Tech Experience Index

New cars are basically rolling computers. Everything from the engine to the infotainment runs on a series of ones and zeros, and a lot of that technology requires input from the driver. So it's no surprise that JD Power has a study designed specifically to discern which bits of tech drivers love and which bits they loathe. "New technology continues to be a primary factor in the vehicle purchase decision," says JD Power's Kristin Kolodge, executive director of driver interaction & human machine interface research. "However, it’s critical for automakers to offer features that owners find intuitive and reliable. The user experience plays a major role in whether an owner will use the technology on a regular basis or abandon it and feel like they wasted their money." The J.D. Power 2020 U.S. Tech Experience Index (TXI) Study found that Volvo owners are happiest with the technology packed inside their vehicles, followed by BMW and Cadillac, all brands that JD Power classifies as premium. The highest-rated mainstream brand is Hyundai, followed by Subaru and Kia. As was the case with the organization's Initial Quality and APEAL studies, Tesla's numbers aren't officially included because they are the only automaker that has not granted JD Power approval to contact its owners in states that require it. Tesla's projected score of 593 would have put it in second place, right behind Volvo's score of 617. The lowest-ranked brand in the TXI Study is Mini, with Porsche right behind. Diving a little bit deeper, JD Power's findings suggest that the technologies new car buyers care most about are related to helping them see their surroundings better. Camera systems, including rear-view mirror cameras and ground-view cameras, scored highest in five of the six satisfaction attributes measured in the study. The technology that owners could really do without? Gesture controls. Owners who answered JD Power's survey say they don't use gesture controls much at all after initially trying them, and they don't really care if their next vehicle has them. We have to wonder if those responses might be what kept BMW out of the top spot. The TXI Study also found that owners are split on automated driving helpers, like lane-keeping assist and automatic emergency braking. JD Power suggests that owners may need more training on those systems before they learn to trust them. Related Video: This content is hosted by a third party.

AAA says Tesla Model S is the best green car available

AAA has released its 2014 Green Car Guide (PDF), a 140-page document that discusses what it means to be green, how to be a greener driver, how to shop for green cars, what choices are available and what green cars are on the horizon. Most importantly, the guide evaluates and ranks 83 different green vehicles, from high-mileage gasoline vehicles to battery electric cars, and everything in between. This year's king of green vehicles, according to AAA, is the Tesla Model S. Despite some interpreting this to mean that AAA is calling the Tesla Model S (with 85-kWh battery) the greenest car, the scoring system only includes two "green" categories out of the 13 evaluated: emissions and fuel economy; the Tesla earns 10 out of 10 in both, but so do every other EV on the list. The other categories include braking, crashworthiness, visibility, slalom handling, ride quality, interior noise, acceleration, ease of entry and exit, interior size, turning circle and luggage capacity. The Model S scored very well (more than 7 out of 10 points) in every category except the last four mentioned. So, this isn't about whether the Tesla is the greenest of the lot. Instead, it's about the AAA deeming it the best all-around car of the green bunch. The best green car value is the gasoline-powered Chevrolet Spark 1LT at $229 per point. AAA also calculates the cost per point for the 83 cars tested. The best green car value, according to this evaluation, is the gasoline-powered Chevrolet Spark 1LT at $229 per point. The Tesla Model S is in the bottom five, at $953 per point. So while the Tesla might be AAA's best green car, those points don't come cheap. In terms of the greenest car available, there are other evaluations out there. For instance, the American Council for an Energy-Efficient Economy (ACEEE) released its own list earlier this year, using broader methods for evaluating what makes a car green, including emissions, fuel economy, curb weight and battery weight (the latter two are used to inform environmental impact of production and disposal). Their top three green cars are the Smart Fortwo Electric Drive, Toyota Prius C and Nissan Leaf. The Tesla Model S isn't even in the top 10. Oh, and let's not forget Green Car Journal's Green Car Of The Year, the Honda Accord. Still, which car would you rather drive every day?

Tesla sending free replacement wall charger adapters after garage fire [UPDATE]

Tesla Motors is about to mail off a lot of packages. The California-based electric vehicle manufacturer is going to send out replacement, upgraded wall charger adapters to customers with official Tesla charging units. The reason is a recent garage fire that involved a Tesla Model S and a company wall charger, even though fire investigators said that the car was not responsible and Tesla said the wall unit did not play a role in the blaze. Tesla CEO Elon Musk said in an interview with Bloomberg today that replacement adapters will be mailed out in the next two weeks. Musk said fires and overheating adapters are "very rare events, but occasionally the wiring isn't done right. We want people to have absolute comfort, so we're going to be providing them with an upgraded adapter." The new adapter has a thermal fuse that will shut off if it gets too hot. Musk did not say why the original wall charger adapter apparently did not have a thermal fuse in the design. AutoblogGreen has asked Tesla how many adapters will be sent out and if this is a global or US-only replacement program, but as of press time, we have not received a response. We're also not sure if this will trigger a recall - the adapter is not, technically, part of the car - and hope Tesla can clarify this point soon. Tesla's first reaction to that garage fire in November was to update its charger software to automatically reduce the charge current under certain circumstances. To date, that incident in Irvine, CA is the only garage fire involving a Tesla wall charger that has been made public, but there are multiple reports of Tesla wall chargers heating up and melting, (see here, here or here), so it appears Tesla is trying to be safe rather than sorry. UPDATE: Tesla has issued a press release on this program, which is now available below. TESLA PROVIDES CUSTOMERS WITH UPGRADED CHARGING SOFTWARE AND ADAPTER FRIDAY, JANUARY 10, 2014 PALO ALTO, Calif. – A variety of factors such as corrosion, physical damage to receptacles, or inappropriate wiring or installation of electrical outlets can cause higher than normal electrical resistance when using the Universal Mobile Connector ("UMC") NEMA 14-50 adapters to charge Tesla Model S vehicles. When charging, higher than normal electrical resistance connections to external energy sources may cause excessive heating of the adapter.
