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.

Ram issues recall on heavy-duty pickup transfer cases

UPDATE: A previous version of this story said the issue only occurred in four-wheel drive. This is incorrect – issues are only exhibited in two-wheel drive. The Basics: Ram is recalling 930 3500, 4500, and 5500 heavy-duty pickups from model year 2016. The affected 3500s were built between July 24, 2015 and January 7, 2016, while the larger 4500/5500 trucks were screwed together between July 24, 2015 and October 8, 2015. The Problem: According to the official NHTSA bulletin, the "transfer case may have been manufactured with a misshapen main output shaft, creating voids that may cause a shaft fracture." If this happens, the vehicle could lose power. The driver might not be able to select park, either. Injuries/Deaths: FCA isn't aware of any injuries or deaths related to the issue. The Fix: Dealerships will replace the transfer case on affected trucks. If you own one: You probably don't. According to FCA spokesman Eric Mayne, dealers haven't delivered the majority of the affected trucks to customers. But if you really do own one, Mayne added that the issue only occurs in two-wheel drive. We'd advise keeping it in four-wheel drive until you can report to your local dealer. FCA kicked the recall off on August 10, so expect a mailed notification soon. Related Video:

Ram 1500 Texas Ranger Concept celebrates brand's law-enforcement partnership

While the auto industry's eyes are fixed on New York for its annual extravaganza at the Javits Center, Ram is making an end-around play. The truck maker is showing a new concept at the 2015 Dallas Auto Show based on the company's long-running partnership with the Texas Rangers (the lawmen, not the baseball team). Exterior changes to the 1500 are kept rather light, with badging inspired by the Rangers' iconic badges fitted to the front fenders and tailgate. The Rangers' badge is also found at the center of each 20-inch alloy wheel. As for the white/silver color scheme, it "embodies the white hats and silver badges that the good guys always wear." Starting with the handsome Canyon Brown and Tan leather of the Laramie Longhorn, Ram designers fitted four, five-peso coins to the door inserts. Texas Rangers' badges have long been hewn from the limited-issue Mexican currency, hence its inclusion in the 1500. The coins in the front door show "heads" and the back door coins are flipped to "tails." Adding to the unique touches, a prominent Texas Rangers' badge sits over the center console and is also embossed in the leather seatbacks. Even the dash cluster's display shows the Rangers' badge upon startup. Ram and the Texas Rangers formed their partnership back in 2014, with the truck maker "aiding the preservation of the history of the renowned law-enforcement organization," the company said in its press release. You can check out the full gallery of images, which include plenty of updated interior shots, above. As for Ram's press release, that is, as usual, available below.
