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.

Ford F-450 claims best-in-class towing, company abandons practice of removing items to boost payload number

The ongoing heavy-duty truck battle between Ford and Ram is showing no signs of slowing down. The Blue Oval is trying to remove at least one point of contention between the two brands by testing its 2015 F-450 Super Duty using the Society of Automotive Engineers J2807 towing standard, which Ram also uses. In the new evaluation, the F-450 is rated at a max towing capacity of 31,200 pounds. That's an identical amount as under Ford's own, previous test.
"We leave no doubt with customers that the F-450 pickup truck has best-in-class towing of 31,200 pounds - whether tested using our own internal towing standards or SAE J2807," said Raj Nair, Ford group vice president for Global Product Development, in the company's release.
At the same time, Ford is also changing how it calculates the F-450's payload. Instead of using its minimum curb weight as before, the brand is now using the truck's base curb weight. The revision lowers the pickup's rating to 5,300 pounds, compared to 5,450 pounds previously. The company said in its announcement that the reason for this is "aligning its payload rating practices with other manufacturers to make it easier for customers to compare vehicles." General Motors made a similar switch for its pickups in August.

Ram introduces 5th and final 'Built to Serve' edition

Ram introduced the fifth and final variant of its "Built to Serve" pickup series Tuesday. Finished in Spitfire (orange) or Bright White, this final version honors the Coast Guard.  "We owe a huge debt of gratitude to our armed forces and the brave men and women who serve them. These 'Built to Serve' models are just one way we honor those who have selflessly served our country," said Mike Koval Jr., Ram Brand Chief Executive Officer – Stellantis. "Whether civilian or military, Ram truck owners are very familiar with this adage as itÂ’s something we strive to build into every truck and van we produce." The trucks were originally slated to roll out in increments between Veterans Day 2019 and 2020, but it appears the release cadence may have been interrupted slightly by the many calamities of the past year. Each of the five comes in one of two special colors chosen to "evoke the spirit, the mission and history of that service," and a limited build number. These are the final of 10,000 (1,000 more than Ram initially planned) "Built to Serve" editions divvied up so that each branch gets two appropriate color choices out of 10 total: Gator (1,000 units) and Diamond Black (1,000); Ceramic Gray (1,000) and Patriot Blue (1,000); Anvil (1,250) and Billet Silver (1,500); Tank (1,000) and Flame Red (1,000); and Spitfire (500) and Bright White (750).  Available on every body style and powertrain, a Built to Serve package costs $2,795. Every truck comes with the 4x4 Off-Road Group, which bundles features like all-terrain tires, an electronic-locking rear axle, hill descent control, tow hooks, and four thick skid plates. They're easy to spot thanks to their prominent rear quarter panel decals. Cosmetic upgrades include an all-black grille and surround, black badges, side steps, black four-inch exhaust tips, body-colored wheel arch trim, and 20-inch wheels finished in Technical Gray.  Ram has used the series to help bring more attention to a volunteer initiative the automaker has run since 2015, not-coincidentally called Built to Serve.  Related Video: This content is hosted by a third party.
