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.

BMW 1 Series prototype packs direct water injection

Just a few months ago, BMW showcased an M4 that was modified to serve as the safety car for the MotoGP racing series. The flashing lights and emergency equipment, however, weren't the only modifications BMW made to the performance coupe. It also packed an innovative new water injection system. And now it's furthering the development of that system by running it in a 1 Series hatchback as well. Revealed at the BMW Group Innovation Days 2015 event, this five-door 1 Series packs a three-cylinder gasoline engine – like the one found in a Mini or i8 – but fitted with the direct water injection system. In this application, the system sprays a fine mist of water – yep, regular old H2O – right into the combustion chamber. While mixing water with gasoline normally wouldn't be recommended, in this case it evaporates immediately and helps cool the engine from the inside, allowing it to run at higher efficiency. That cooler running engine brings with it several benefits. It delivers improved fuel economy and lower emissions, to start. It also allows for an earlier ignition point, higher compression ratio, and higher boost pressure in turbocharged engines, delivering increased output. It even cuts down on engine knocking (where combustion occurs spontaneously), reduces wear and tear on the engine, and makes better use of lower octane levels. If that sounds like a win-win-win... win (we're losing count of all the wins here), it's because BMW just may be on to something. Of course it does require a water tank to be fitted on board, which means added weight, but instead of requiring the driver fill up the water tank, BMW has fitted this prototype with a system that replenishes the water level from the air conditioning system when the vehicle is switched off. So unless it's being driven in a particularly extreme climate, it doesn't even need topping up. Add one more "win" to the list, then. Extra power, improved real-world fuel economy: Direct water injection enhances efficiency. With direct water injection for turbocharged petrol engines, the BMW Group has again succeeded in enhancing the capabilities of conventional engine technology through an ongoing process of refinement and improvement. The precisely controlled injection of water into the engine cylinders produces a cooling effect that boosts power and torque, particularly when operating at or near full throttle, while at the same time reducing fuel consumption and emissions.

We'll finally see the BMW M2 in Detroit

Despite being unveiled in October, the world will finally get to meet the BMW M2 at the Detroit Auto Show. The entry-level M coupe brings 365 horsepower and 343 pound-feet of torque from the M TwinPower Turbo engine, as well as an active rear diff and lightweight components. We'll also get close-up looks at the intense exterior design, which seems to have opinion divided opinion concerning its front fascia. The X4 M40i will also storm Detroit, its inline-six M Performance TwinPower Turbo with 355 hp and 343 lb-ft is also making a world debut. This isn't a proper M version of the X4, but there's been heavy revision throughout the crossover-coupe, and it gets special 19-inch wheels to stand out. Elsewhere of note on the stand will be the 330e and 740e plug-in hybrids that we first met in Frankfurt, and the i8 with laser lighting. The press release below has more. BMW M2 AND BMW X4 M40i TO MAKE WORLD DEBUTS AT THE 2016 NORTH AMERICAN INTERNATIONAL AUTO SHOW IN DETROITAdditional Featured BMW Vehicles include: BMW 330e, BMW X1, BMW 7 Series and BMW i8, among others.18.12.2015 - The BMW M2 and X4 M40i will make their world debuts at the 2016 North American International Auto Show on Monday, January 11, at the BMW Stand at 10:05 a.m. in Detroit's COBO Center (One Washington Boulevard Detroit, MI 48226). In addition, BMW will feature the new, BMW X1, BMW 7 Series, the plug-in hybrid BMW 330e, the high-performance BMW i8 and the all-electric BMW i3 among other BMW models at the BMW Stand. English, German and Spanish speaking BMW representatives will be available for interviews throughout the day.Making its highly anticipated world debut, the 2016 BMW M2 features the renowned BMW M Performance complimented by a sleek interior and exterior design. A newly developed M TwinPower Turbo technology 3-liter, 6-cylinder engine produces 365 bHP and 343 lb-ft of torque, catapulting the high performance vehicle from 0-60 mph in 4.2 seconds. Inspired by its motorsport history and enhanced by BMW EfficientDynamics technology, the BMW M2 sets the pace in its segment when it comes to agility, driving feeling, directional stability, steering precision and controllability at the limit, without any compromise in everyday use. The 2016 BMW M2 will be available in US showrooms in spring 2016. Pricing will be announced shortly. BMW M2 Press Kit.The BMW X4 M40i also will make its world debut in Detroit.
