New J.D. Power Initial Quality Study puts Porsche, GM in spotlight

J.D. Power and Associates has released its annual Initial Quality Study, and this year, Porsche and General Motors took the spotlight. The study, which asks new car owners to report problems experienced during the first 90 days of ownership, found that overall, the industry averages 113 problems per 100 vehicles.
Porsche managed a score of just 80 problems per 100 vehicles, while GMC took the second spot on the podium with 90. Lexus filled out the top three with 94 problems per 100 vehicles, followed by Infiniti at 95 and Chevrolet at 97. The study also looks at specific models, and found the Lexus LS to enjoy the best initial quality at 59 problems per 100 vehicles.
Interestingly enough, the report found that around two-thirds of most owner problems experienced in the first 90 days are attributable to vehicle design instead of mechanical failure. Specifically - echoing a refrain we've been hearing for the last few years - owners are having a hard time figuring out how to use the technology present in their new vehicles. Head over to the J.D. Power site for more information, or scroll down below for the company's related press release.

2014 GMC Sierra Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.
While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed - a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero - there's always been some Mythbusters-level contention about such things -but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.

GM confirms 2015 Silverado, Sierra to get 8-speed automatic

When viewed alongside the next Ford F-150 and the Ram 1500, there is one thing that seems to be missing from the Chevrolet Silverado and GMC Sierra. Where the F-150 will rely on turbocharging and aluminum architecture and the Ram sports an eight-speed automatic and an air suspension, the General Motors twins lack a big, calling-card feature. They're very good, very refined trucks, but one could argue that they're not terribly innovative.
And while it might not be as flashy a feature as air suspension or a lightweight skin, the Silverado and Sierra will get their own eight-speed automatic for 2015, a transmission that will be paired with the company's Ecotec3 6.2-liter V8. The new cogswapper will also find its way into the GMC Yukon Denali, but for now, there's no indication why the Cadillac Escalade, Suburban, Tahoe and standard Yukon are being left out.
According to GM, the new gearbox is about the same size and weight as the current Hydra-Matic 6L80 six-speed. By the time the new powertrain combination enters production late this year, the EPA will almost certainly have gotten around to certifying the vehicles' fuel efficiency. Until then, feel free to speculate. The current Silverado with the 6.2 and six-speed auto returns 14 miles per gallon in the city and 20 on the highway. How much do you think the eight-speed will improve those figures? Scroll down for the official press blast from General Motors, and then head into Comments.
