Maxwell RHEV Prototype First Drive Review | More than meets the eye

The Maxwell RHEV looks just like any small business' panel van, sporting large vinyl graphics and unassuming steel wheels. You'd have no idea that the co-founders of the startup based out of Seattle had grafted a salvaged Voltec powertrain from a junkyard Chevy Volt into this Ram ProMaster. Somewhere, a battery pack lurks. Maxwell's co-founders, CEO Max Pfeiffer and engineer Trey Camp, open the cargo area to reveal a completely unaltered space. Both are ex-Tesla employees with a long fascination for the #vanlife movement – that their interests intersected in a hybrid cargo van isn't surprising once you start talking to them. This is their first vehicle, a salvaged ProMaster sidelined with a blown 3.6-liter Pentastar, and it's both their prototype and the only Maxwell in existence right now. That said, the company is building a low-roof version for a customer, which will be lighter, have less aero drag and therefore be more efficient. The company is just emerging from a stealth startup mode, and while their backstory is fascinating, I'm still wondering where the Volt's 18.4 kWh battery pack is. "There's nothing in the back ... we're able to get the battery underneath the floor, in the center," Pfeiffer says. Ducking my head under the side reveals, sure enough, a little underside blister that contains the battery, tucked up neatly. The other changes to the RHEV – short for Range-extended Hybrid Electric Vehicle – are minimal. He pops the hood. There are some rough edges, but the 1.5-liter, 101-horsepower engine and 48-kW motor fit comfortably on custom engine mounts and with re-routed exhaust, behind a fascia that improves aero and houses the charge port. Custom axles send power to unaltered Ram hubs and brakes. "This version, it's a little bit prototype-y," Pfeiffer says. "We've had more time to work with the CAD [computer-aided design, engineering drawings] we were able to get from GM and Chrysler, and we've done a better job packaging for production." GM already spent billions on the Voltec and its controlling software, and Maxwell can happily ride those coattails. Despite the help GM has lent Maxwell, there are no official ties. An emulator sends spoofed signals to the Ram instruments, which have a new custom-printed face. The Ram's body control module is left alone. For powertrain faults, Maxwell says the vehicle can theoretically be serviced by any Chevy dealer, and any issue with the rest of the vehicle can be handled by a Ram service shop.

Chrysler readying 20 Moparized vehicles for SEMA

The Las Vegas Convention Center has plenty of space for aftermarket companies and automakers to show off their wares, and it looks like Chrysler is taking advantage of the spacious floor plan. At next month's SEMA Show, Chrysler will have a full 20 cars from its six brands decked out with Mopar gear.
As a hint of what is to come, Chrysler released a handful of teaser sketches showing glimpses of modified Jeep Cherokee, Ram 1500, Fiat 500L and Chrysler 300 concept vehicles. The automaker will also use the venue to show off a new line of Jeep Performance Parts offered by the all-new Mopar Off-Road Division. In addition to the images, Chrysler also issued a brief press release - posted below - breaking down some of the "industry-first features" that Mopar has offered in recent years.

2019 Ram Heavy Duty will have more than 170 available Mopar parts

When it comes to factory-backed modifications, few do it better than FCA's Mopar division. Just look at all the gear that's ready at launch for the new 2020 Jeep Gladiator pickup. In the past month or so, we've seen the debut of the Ram 2500 Heavy Duty and 3500, 4500 and 5500 chassis cab models. At the tail end of the 2019 Chicago Auto Show, FCA revealed a whole host of Mopar parts for the heavy-duty Rams. The display truck is a 2019 Ram 2500 Heavy Duty Big Horn with the 6.4-liter Hemi done up in FCA's Blue Streak paint. Most of the parts are going to be ready at launch, though Mopar says some are just concepts at this point. Actual parts include a black powder-coated "Ram Bar" in the bed fitted with five 5-inch LED lights. The lights are triggered by a switch box in the cab. Other Mopar parts on the truck include a bed step and fender flares as well as interior bits like rubber floor mats and stainless steel door handles. The truck is also fitted with a number of parts that aren't actually available. That includes the 17-inch beadlock wheels fitted with Goodyear tires. There are also rock rails and a bed-mounted spare that's good for up to 37-inch tires. Outside of the truck, Mopar will have a number of parts available at the 2500's launch. Customers can get a trailer camera, fifth-wheel hitch, gooseneck ball kit, bed extender, bed liner, a cargo ramp, toolboxes and more. Related Video:
