2016 Chevy Malibu exhaustively tested with four decades of data

Chevy is preparing to unveil its new Malibu sedan at the upcoming New York Auto Show next month. But when it does, it's not like it will have appeared overnight. The development of any new vehicle – especially one as widely produced by a major automaker as the Malibu – involves rigorous and relentlessly punishing tests. In the Malibu's case, that meant 1.5 million miles of driving from the scorching heat of Arizona in July to the frigid cold of northern Canada in January and everything in between. The Bowtie brand also says it incorporated four decades' worth of data taken from vehicles driving in locations around the world since 1972 in order to make the Malibu the best it could be. We'll have to wait to find out the results of all that exhaustive testing, but you can catch a sneak peek at the new sedan in the video above. Four Decades of Data Used to Test 2016 Chevrolet Malibu Recorded customer use drives durability testing for next-generation midsize sedan 2015-03-11 DETROIT – Data collected over decades from across the globe is helping ensure the 2016 Chevrolet Malibu can handle the world's worst roads even if the all-new midsize sedan never drives on them. Data collection boxes are placed in cars in real-world driving conditions around the world. Since 1972, these devices have accurately recorded the harshness and frequency of every jounce, bump and shudder inflicted on the car on roads in the U.S., Russia, Saudi Arabia and developing markets. "Although most Malibu owners will never put their car through similar abuse, we test all new vehicles in extreme climates, inclement weather and on punishing road surfaces," said Dan Devine, Malibu validation engineer. "The 2016 Malibu is definitely up to these challenges." Tests like these ensured the current generation Malibu was dependable and durable, two qualities that in turn helped Malibu stand out from its rivals in important quality surveys, such as J.D. Power's Initial Quality Study and Vehicle Dependability Study. General Motors engineers analyze the data to calculate the precise amount of damage potholes and other hazards create over 150,000 miles. Then the conditions are replicated at GM's Milford Proving Ground in Michigan on three unique road courses, each riddled with simulated potholes of increasing severity. Engineers run preproduction cars through the course up to hundreds of times.

GM alerting truck and sedan owners to a do-over on brake recall

A recall campaign intended to address issues with braking systems on certain 2019 General Motors trucks and sedans may have introduced a new issue, the automaker has acknowledged, and thousands of owners driving repaired vehicles may need to return to their service departments for another update.  The update addresses a fix that was pushed out to owners of more than half a million brand-new GM trucks and sedans that could potentially lose partial braking function, according to the Detroit Free Press. The original software fix helped address situations where the vehicles' anti-lock braking systems would become disabled, which in turn would prevent electronic stability control from activating. Vehicles subject to the recall would often experience software glitches that prevented them from properly communicating the operational state of these systems, meaning drivers would have no idea that their brakes may not behave as expected in an emergency. The 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 were all recalled in the original campaign.  Unfortunately, the early version of this fix appears to have introduced yet another software glitch, indicating that the original fix did not do the trick. Those who have not yet had their cars serviced can rest easy; they will only receive the most up-to-date version of the software fix.  Related video    

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.
