Thanks to smaller engines, vehicle dependability falls for first time in 16 years

As automakers have made engines smaller and smaller to improve fuel economy, problems in those vehicles have gotten bigger and bigger. That's the synopsis of a J.D. Power vehicle-dependability study, which found that dependability dropped for the first time in 16 years, largely because the proliferation of four-cylinder engines is causing the vehicles to be less reliable. Specifically, the number of problems per 100 vehicles (or what J.D. Power calls PP100) during the past 12 months for 2011 model-year vehicles rose six percent from the year-earlier figures for 2010 model-year cars. Singling out four-cylinder vehicles revealed about a 10-percent increase in problems during the past year. This issues largely related to engine hesitation, rough transmission shifting and lack of power, signaling the inability of vehicle makers to iron out some of the problems in their smaller engines as they strove for better fuel economy. Six- and five-cylinder engines proved far more reliable. Among car brands, BMW's Mini sub-brand came out as least reliable, with 185 problems per 100 vehicles during the past year. Toyota's Lexus badge was easily the most reliable, with just 68 problems per 100 vehicles. Coming in second place was Mercedes-Benz. The overall average was 133. Check out J.D. Power's press release below. J.D. Power Reports: Increased Engine and Transmission Problems Contribute to Decline in Vehicle Dependability for The First Time in More Than 15 Years General Motors Company Receives Eight Segment Awards, While Toyota Motor Corporation Garners Seven and Honda Motor Company Earns Six WESTLAKE VILLAGE, Calif.: o Owners of 3-year-old vehicles (2011 model year) report more problems than did owners of 3-year-old vehicles last year, according to the J.D. Power 2014 U.S. Vehicle Dependability StudySM (VDS) released today. The study, now in its 25th year, examines problems experienced during the past 12 months by original owners of 2011 model-year vehicles. Overall dependability is determined by the number of problems experienced per 100 vehicles (PP100), with a lower score reflecting higher quality. The study finds that overall vehicle dependability averages 133 PP100, a 6 percent increase in problems from 126 PP100 in 2013. This marks the first time since the 1998 study that the average number of problems has increased. "Until this year, we have seen a continual improvement in vehicle dependability," said David Sargent, vice president of global automotive at J.D.

Lexus looking for performance with 600-hp LF-LC?

Lexus has been keeping development of the production version of its LF-LC concept tightly under wraps. Last we heard, that halo GT car had received the green light for production, but that was over a year ago. Since then, things have been pretty silent. Finally though, fresh rumors about the luxury coupe are starting to leak out, pointing toward the model's powertrain lineup.
According to unnamed sources speaking to Motor Trend, the production LF-LC will eventually sport three very intriguing engine options. The base model will reportedly use a naturally aspirated V8 providing around 450 horsepower - very similar specs to the upcoming RC F. The next step up will allegedly be the upcoming hybrid powertrain shared between BMW and Toyota pumping things up to around 500 hp. Finally, a top-of-the-heap F version will use a twin-turbocharged version of the RC F's 5.0-liter V8 to bring output to 600 hp. The insiders even claim that the hybrid and the twin-turbo V8 could find their way into other Lexus products like the LS and possibly even a more beastly RC.
None of this speculation sounds too outlandish. Lexus could get more capacity out of the RC F's tuned V8 by shoving it into other models, and rumors are flying about performance cars spawned from BMW and Toyota's partnership. Given Lexus' recent embrace of turbocharging, even the twin-turbo V8 doesn't seem too dubious. That said, with no hard facts to back up the rumormill, we'll have to keep waiting to see what the LF-LC shows up with.

Recharge Wrap-up: Tesla breaks dyno on video, Lexus trademarks 'LS 500h'

A video shows a Tesla Model S P85D breaking a dyno during a test. Starting at a slow roll, the instant torque under full power snapped a belt on the dynamometer. Before it broke, the dyno measured over 700 pound-feet of torque from the all-wheel-drive Tesla. A previous dyno run saw the car reach its 155-mph top speed and a peak 435 horsepower. See the video above, and read more at DragTimes. Lexus has filed a trademark for "LS 500h" in Europe. This calls for some speculation as to what this means for an upcoming model. It could be that Lexus plans to release the LS with a new powertrain, perhaps a 4.0-liter engine with a hybrid system. Maybe it will use the 3.5-liter V-6 with a more powerful hybrid system. The LS 600h could simply be getting a new name. Or, we might not see the LS 500h badge used at all in the near future. Note that Lexus trademarked LC 500 and LC 500h in Canada last year, and we've seen no such cars yet. Read more at Hybrid Cars. Ethanol producers have strong words in response to the American Petroleum Institute's claims for demand for ethanol-free gasoline. The API and National Marine Manufacturers Association have urged the EPA to consider marine and small engine demand for E0 gasoline when setting Renewable Fuel Standard volume requirements. Big Oil is using a "false narrative to discourage the use of a cleaner, less expensive, homegrown renewable fuel," according to Growth Energy CEO Tom Buis. Buis says ethanol doesn't cause problems in marine and small engines, a statement backed by the Outdoor Power Equipment Institute. "What probably does concern boaters is the amount of time they spend dry docked as a result of oil spills, like the one that dumped 21,000 gallons of oil along four miles of coastline in Santa Barbara, California," says Buis.
