40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

Somebody created a Dodge Challenger SRT Demon droptop

The Dodge Challenger SRT Demon is a vehicle built with one purpose in mind: going fast down a drag strip. Weight is the enemy when it comes to acceleration, and one surefire way to add weight to a car is to make it into a convertible. However, that’s exactly what one Demon owner decided to do to their Challenger. Motor Authority spotted this Plum Crazy Demon convertible conversion for sale online, and the dealer and builder even spilled a few details on the car itself. This particular conversion was done by Droptop Customs, a shop with experience, having previously converted a couple Challengers into convertibles for Shaq in Miami. However, ripping the roof off the 840-horsepower Demon is no small task. ThatÂ’s a ridiculous amount of horsepower to handle for a car that has lost a fair amount of structural rigidity from removing the roof. The Droptop Customs sales manager told MA about the changes that were made to make this build work. To begin, the frame rails were reinforced with 1x2-inch pieces of metal. Then, the shop added diagonally-mounted metal braces underneath to resist twist. Even more structural supports were added to the trunk, front and rear shock towers, and gussets were added to the bottom of each door to keep them from moving. Lastly, the shop boxed the connection of the front rails to the engine cradle. No specifics about weight gain were provided. There is one sad bit of news about this Demon, though. The dealer told MA that itÂ’s currently on consignment, despite being listed for sale on FCA dealership Cape CoralÂ’s website. ItÂ’s priced at an eye-watering $145,995. But the new owner wonÂ’t have to manually put down the top! ThatÂ’s right, itÂ’s powered, and itÂ’s supposed to take about 20 seconds to lower or raise into place while stationary. Somehow, the car has only 172 miles on it, so itÂ’s hardly been used. We have no photos with the top up, so youÂ’ll have to settle for top-down photos for now. It looks like a professional job through and through, and we actually dig the convertible look. Plus, who doesnÂ’t love Plum Crazy? 

Stellantis aims to eliminate separate inverter, charger to improve EV efficiency

Stellantis has announced that, in collaboration with French battery company Saft and French National Center for Scientific Research, has made significant progress in eliminating two major components of an electric vehicle powertrain: the on-board charger and the power inverter for the motor. The company claims that doing this will allow for better space use in vehicles, as well as improvements in efficiency, cost and reliability of components. As a quick primer, also explained in the below video, the on-board charger and power inverter are sort of translators to get the right current to different parts of the electric powertrain. The on-board charger takes AC power from the grid and converts it to DC to charge the batteries. Then when power goes from the batteries to the electric motor, the power inverter converts that DC power back to AC. These components aren't exactly small. Frequently you'll find them packaged somewhere under the hood. What Stellantis and its cohorts have developed, and have been using on a test vehicle since last summer, are small power inverter boards that can be mounted very closely to the battery packs. They can handle both conversion needs, for charging and discharging, instead of needing two separate devices. The most obvious perk to this is that you can do away with those traditional components and free up more space, either for making smaller vehicles without losing interior volume, or adding space to a vehicle that wouldn't have had it otherwise. There's the additional benefit of reduced weight, something that EVs struggle with. Stellantis also claims improvements in efficiency, reliability, and cost, however, it didn't go into detail as to how this setup would do that exactly. We'll try to get in touch with representatives from Stellantis in order to get more information. We're still a ways out from seeing this technology in production Stellantis vehicles. The company said it aims to apply it to vehicles by the end of the decade. Saft is also looking at using it on stationary battery systems as well. So maybe we'll see it on a 2029 Ram 1500 REV, but for now, we'll be living with traditional chargers and inverters. Related Video: Green Alfa Romeo Chrysler Dodge Fiat RAM Technology Electric
