GM threatens predatory dealers with order cancellations, non-transferrable warranties

General Motors will launch a second salvo against misbehaving dealerships next week with a new set of policies aimed at curbing predatory markup strategies. With the new Chevrolet Corvette Z06, GMC Hummer EV SUV and Cadillac Escalade-V about to head into production, GM is putting its foot down yet again. Dealers that attempt to circumvent GM's markup restrictions by dealing directly with brokers or other resellers could find themselves in a particularly nasty spot, as the company is threatening to withhold future allocations and end the transferability of warranties when dealers facilitate the reselling of vehicles within 12 months.  While this may help curb some dealership chicanery, it's possible the real loser in such a deal could end up being the customer who unwittingly ends up with an un-warrantied vehicle. We suspect GM has accounted for that, but we'll have to wait until next week to find out exactly how these new policies will be enforced.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Electric pickups compared: 2025 Ram 1500 REV specs vs. Silverado EV, F-150 Lightning

Now that the 2025 Ram 1500 REV has been revealed, along with its most important specifications, we now have information on all of the mainline Big 3 electric full-size pickup trucks. So it's time to see how the numbers stack up, because trucks are all about numbers. We'll see how the Ram compares to the power, battery capacity, payload, towing and other features of the 2024 Chevy Silverado EV and the 2024 Ford F-150 Lightning. Power and torque The Ram has just one powertrain option. It features two electric motors making 654 horsepower and 620 pound-feet. That gives it the most powerful standard powertrain, if not the most torque, as the Chevy Silverado EV has 510 horsepower and 615 pound-feet of torque, while the F-150 Lighting has 452 horsepower and 775 pound-feet. But the Chevy and Ford each have upgraded motor combinations. The Silverado is the most potent with 754 horsepower and 785 pound-feet, and the F-150 has 580 horsepower and 775 pound-feet. The GMC Sierra EV will also be available with this more powerful pair of motors, and most of its specifications will be the same as the Silverado. There are a couple of exceptions which we'll note when they come up. All three trucks come standard with dual motors and all-wheel drive, regardless of output, battery or trim level. They're all available with locking rear differentials, too. Ford F-150 Lightning front low View 48 Photos Battery, range and charging The Ram is packing some serious packs of batteries. The standard model gets 168 kWh and an estimated range of 350 miles. And the optional 229-kWh pack is estimated to deliver 500 miles of range. That's more capacity and range than the others. It also boasts an 800-volt battery system that allows for close to 350-kW charging. The Ford F-150 Lightning has a base battery of 98 kWh with a range around 230 miles. Optional is a 131-kWh pack with between 300 and 330 miles of range, depending on other vehicle specifications. It's the slowest charger, only allowing 150-kW charging maximum. The Silverado EV's battery specs are a bit nebulous. At launch, it will only be available with one battery pack option that GM claims will provide around 400 miles of range. The company didn't give an exact capacity, though. We would guess its size falls between the Ram's 168 and 229 kWh packs. A smaller battery pack will be offered later, with a shorter but unknown range. The Silverado can use 350-kW fast charging like the Ram.
