Chevy preparing new Camaro ZL1 Convertible?

It's a given that when an automaker introduces a new performance model, it's only a matter of time before an even hotter variant arrives. The Ford Mustang begets the Shelby GT350 and the Dodge Challenger R/T spawns the SRT 392 and Hellcat. And for Chevrolet, that progression sees the Camaro SS evolve into the ZL1. That's probably what our spies have captured here. The convertible variant of GM's most powerful Camaro is betrayed not by its big, black wheels or quad exhaust tips – both of those items have been fitted to the far tamer 1LE in the past – but by its brakes. To put it simply, they're enormous. The old ZL1 had 14.6-inch rotors in front and 14.4-inchers in the back, with Brembo-branded six-piston calipers up front and four-piston binders at the rear. While the overall size of the calipers doesn't appear to have changed much, it looks like the rotors – especially in front – seem to take up a larger space inside the front wheels than in last year's model. Perhaps Chevy moved to a straight 15-inch rotor? It's difficult to discern any more from these images, though. Chevy did a fine job with the camouflage, making it difficult to pick out ZL1-specific body parts. From the rear spoiler to the front fascia to the side sills, each body piece looks like it's the same as the standard Camaro or is just completely obscured. If this is a Camaro ZL1, it seems like Chevy may have just stuffed the vital organs inside the body of more pedestrian droptop. According to our spies, it's unlikely that Chevy will mix things up under the hood. Expect the 6.2-liter, supercharged V8 from the Corvette Z06 and Cadillac CTS-V to move the ZL1 from 550 horsepower to around 640 ponies when it debuts for model year 2017. A six-speed manual transmission will be standard, while the Camaro's big brother will probably donate its eight-speed automatic.

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 removes start/stop from full-size trucks and SUVs with V8 engines

GM is removing start/stop technology from a number of its popular full-size SUVs due to the ongoing chip shortage. This follows the removal of cylinder deactivation technology from some of its trucks, which was also due to the chip shortage. GM Authority first reported the news, but we’ve just confirmed everything with a GM spokesperson.  The following 2021 model year vehicles will be affected: Chevy Tahoe, Chevy Suburban, GMC Yukon, Cadillac Escalade, Chevrolet Silverado 1500 and GMC Sierra 1500. Only versions of those vehicles built with the 5.3-liter V8 or 6.2-liter V8 and mated to the 10-speed automatic will have the tech removed from them. Only vehicles manufactured on or after June 7 will be affected. “By taking this measure, it will enable us to continue production of our high-demand full-size SUV and pickups as the industry continues to rebound and strengthen,” GM said in a statement. Those who ultimately buy one of these vehicles without start/stop technology will receive a $50 discount off MSRP for their troubles. Losing this fuel-saving tech could be a big negative for some, but we know many folks turn it off anyway. Not having to press the button to deactivate start/stop every time could actually be a positive if youÂ’re part of the camp who does that already. 2021 Cadillac Escalade Sport Platinum View 27 Photos On the downside, GM says “most of the affected vehicles will experience a minor reduction in fuel economy.” We donÂ’t have revised window stickers in hand to know how each model will be affected, but any 1 mpg reduction will be rather impactful for vehicles rated as low as these trucks already are. Any reduction will be seen in the city mpg rating, so take the kind of driving youÂ’re going to be doing into account before purchasing. When it comes to greenhouse gas compliance rules, GM says it doesnÂ’t foresee this impacting the companyÂ’s average fleet score. It also intends to begin adding start/stop back to these models as soon as possible, but there will be no retrofit effort made to fit the tech to vehicles already built without it. “Our supply chain organization continues to make strides working with our supply base to mitigate the near-term impacts of the semiconductor situation,” GMÂ’s statement reads. “GM continues to leverage every available semiconductor to build and ship our most popular and in-demand products, including our highly profitable full-size trucks and SUVs for our customers.
