GM will compensate SUV owners for fuel-economy error [UPDATE]

General Motors will offer debit cards to owners of some of its crossover SUVs after it was discovered that GM overstated the vehicles' fuel economy on window stickers, Automotive News says. GM will offer reimbursements to about 135,000 customers that are worth between $450 and $1,500 each. Some owners will also have the option of being provided with an extended warranty free of charge instead of the debit card. GM overstated fuel economy on about 170,000 vehicles by one to two miles per gallon because of what it has said was an inadvertent error stemming from not factoring the impact of emissions-related hardware into the EPA window-sticker figures. As a result, GM put a temporary stop-sale on the Chevy Traverse, GMC Acadia, and Buick Enclave before switching out the window stickers on about 60,000 vehicles. Automotive News says letters and debit cards will be sent out next week, and Reuters is estimating that the reimbursement program will cost GM about $100 million. With automakers ranging from Hyundai/Kia to Ford to, more recently, Volkswagen and Mitsubishi being ensnared by emissions or fuel-economy-rating issues, GM is working quickly to address the problem. For those curious, the reimbursement totals, factoring in current gas prices, the SUVs' combined fuel economy, and typical driving of about 12,000 miles a year, will provide between three and 12 months worth of free gas for those drivers (the models get either 17 or 18 miles per gallon combined, depending on front- or four-wheel-drive configuration). While about 135,000 customers will be reimbursed, Automotive News says the fleet buyers of about 35,000 crossovers haven't been addressed yet. UPDATE: GM spokesman James Cain, in an e-mail to Autoblog on Sunday, confirmed that the company will reimburse about 135,000 customers. Purchase customers will be given the option of a pre-paid debit card or a 48-month/60,000-mile protection plan, while lease customers will be offered the pre-paid debit cards. Most of the cards will have a value of between $450 and $900 on them. "We want all of our customers to have a great ownership experience, so we designed this reimbursement program to provide full and fair compensation in a simple, flexible, and timely manner," he wrote.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

These were our favorite cars of 2022

Favorite cars is different than best cars. The idea of "best" can speak to value and overall competitiveness in a given vehicle segment. There's lots of objectivity involved and to do a "best" list right, one really must be very thorough and as scientific as possible. This is not that list. This is about our favorites, so objectivity be damned. If we liked a Challenger Hellcat because it made loud noises or a Honda Odyssey because it made for a particularly special family vacation, fair game. These were the cars that most spoke to our collection of editors and the ones that stayed in our minds and hung in our hearts long after they left our driveway. — Senior Editor James Riswick 2022 GMC Hummer EV Senior Editor, Green, John Beltz Snyder: I didn't particularly expect to like the new Hummer. I wasn't a fan of the Hummer H2 or H3, so I wasn't automatically enthusiastic about this electric reboot. Fast EVs aren't hard to come by — and, in fact, may be too easy to come by — so its performance specs weren't enough to win me over. Despite videos to the contrary, pickups aren't my favorite vehicular format. And its excessive size and weight turned me off ... until I finally got behind the wheel.  This thing is wildly entertaining to drive. Watts to Freedom launch control is a neat party trick, sure, but the novelty wears off quickly. The novelty of Crab Walk, however, has staying power. The rear-wheel steering makes this behemoth feel much smaller than it is — the maneuverability is incredible, and useful. The air suspension provides tons of clearance, including a ridiculously high-riding Extract mode. I can't wait for lesser versions of the Hummer to make their way to market. Give me less power (for less money), but keep the off-road tricks onboard, and I'll be a happy camper. Senior Editor, Consumer, Jeremy Korzeniewski: If I could afford to put one of these in my driveway, I would. Sadly, I can't, so I won't (What's that, Janet? I got the lyric wrong?). Still, I love the dumb thing. Thankfully, I have another choice down below. 2022 Porsche 911 GT3 Associate Editor Byron Hurd: Yeah, duh, Porsches are good. But there's good, and then there's GT3. This is the feeling every performance-oriented RWD tuner is trying to replicate. This is hard, precise, surgical and immensely satisfying. To begin to explore this car on a public road is by itself an admission that you believe yourself to be above the rules as they apply to normal drivers.
