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 says its customers are more excited about V8-powered trucks than EVs

As its rivals invest billions of dollars into electric pickups, Ram made headlines by dropping a supercharged, 702-horsepower V8 engine between the 1500's fenders. While critics will inevitably argue there's nothing forward-thinking about the Hellcat engine, the company explained its customers are more interested in V8s than in EVs. Speaking with Muscle Car & Trucks, 1500 brand manager Carl Lally explained the company is open to the idea of exploring electric powertrains. His comments echo the ones made recently by Mike Manley, the head of Fiat-Chrysler Automobiles (FCA). Ram will begin developing a battery-powered pickup if customers demand one, but it sounds like its market research finds there's not a tremendous amount of interest in a gasoline-free model.  The market research must say otherwise over at Jeep, which is bringing the plug-in electric hybrid Wrangler 4xe to market. "It's fundamental to us that it's not about chasing the [EV] trend, but about chasing what the customer really wants and providing it to them. That changes over time, but today it's a supercharged, 6.2-liter V8 that has them most excited," said Lally, referring to the 1500 TRX introduced as an alternative to the Ford F-150 Raptor. Adding credibility to Lally's statement is the fact that the 702 available units of the TRX Launch Edition model sold out in a couple of hours in spite of a base price of approximately $90,000. Ram is not limiting production of the regular-production TRX, which starts at $71,690, so time will tell if its bet on V8s pays off in the long run. Market leader Ford wants to plant its stake in both segments. We know it's developing an electric variant of the 14th-generation F-150, and an earlier report claims the next Raptor will receive the Mustang GT500's 700-plus-horsepower V8. As for General Motors, it's planning on launching a battery-powered Chevrolet Silverado sooner or later, but it has chosen to watch the horsepower war from the sidelines — for the time being, at least.

Chrysler set to make $266M-investment into 8-speed transmission production

Chrysler will shortly make a significant $266-million investment into its Kokomo, IN transmission factory in a bid to expand production of its eight-speed automatic transmissions. The gearboxes, which are built under license from Germany's ZF Friedrichshafen, have been well received by customers and critics, and according to an SEC filing obtained by Automotive News, the transmissions will eventually find their way to all of Chrysler's rear-drive offerings (Viper and heavy-duty Ram models, aside). According to AN, a Chrysler spokesman says the investment has not been confirmed, but once it is, it'll mark the company's latest in a growing line of investments at the facility. Chrysler has poured $1.5 billion into Kokomo since 2009.
