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.

2014 Ram 1500 Diesel

Remember when Mahindra & Mahindra was close to offering a compact diesel pickup here? A million voices from the truck-and-bed-loving tribes of the Internet cried out at once in anticipation, only to be silenced in disappointment when it didn't happen. And this was for a jitney with a bed that didn't exactly look robust in its press photos. The message these fans had was clear: light-duty truck + a diesel engine = a prayer answered for a significant contingent of truck buyers.
Ram tells us a fullsize diesel half-ton has been the number-one demand from customers, and it will be the first manufacturer to grand the wish when the 2014 Ram 1500 goes on sale early next year - "late availability" in Q1 of 2014 is the official word - with a 3.0-liter, six-cylinder turbodiesel provided by VM Motori. If you're wondering about the engine source, VM Motori has been a Chrysler supplier since 1992. DaimlerChrysler bought VM Motori in 2000, and after a few ownership-stake changes since then, it is presently a 50-50 joint venture between General Motors and Fiat. That will change shortly, however, with Fiat recently announcing it will buy GM's share and take full control of the company.
Driving Notes

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:
