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.

2020 Fiat Ducato Electric is the Ram ProMaster's EV cousin

As we all know, the Ram ProMaster has Italian roots. Despite featuring a 3.6-liter, 24-valve Chrysler Pentastar V6 with 280 horsepower, the ProMaster was born a humble Fiat Ducato over a decade ago, the Ducato's roots stretching far into the past. There was even been a rebadged Alfa Romeo version of the Ducato in the early '80s, so badge engineering isn't a strange concept when it comes to this line of vans. Nevertheless, the mother company has come up with a Ducato that's not propelled by the Pentastar or a European diesel engine: the 2020 Ducato facelift will come with a fully electric powertrain in Europe. The Ducato Electric is the first EV from Fiat Professional, the work vehicle division. Earlier, there have been natural-gas-powered versions, which continue to form a part of the model palette, but a BEV Ducato is unprecedented. Still, or perhaps for that reason, Fiat is taking small steps when electrifying its van lineup: The Ducato Electric will at first be made available to "major clients" via pilot projects, which means trusted Fiat customer fleets will function as beta testers for the van, most likely only in Europe. No technical details are available yet, either, making the Ducato something of a Mystery Machine. These fleets, some of which have already helped to develop the EV van, can pre-order the Ducato Electric this year with the vehicles delivered in 2020. Even if the van's availability has a touch of '90s EV uncertainty, Fiat says there's "no compromise" in the van's load-carrying capacity and performance. We also expect more information to trickle out in the near future, and given how handy a silent yet torquey van is in some use cases, perhaps the Ram version will also get officially electrified at some point. Aftermarket solutions, like the Maxwell RHEV, already exist.

Do you like TRX? New Ram 1500 coming to rock the Raptor off-road

BOLOCCO, Italy — Since the brand was spun off in 2009, Ram sales have been on a roll. Although it had some of the oldest vehicles on the market, the automaker sold nearly 700,000 models in 2017, marking its eighth consecutive year of sales growth. At FCA's Italian proving grounds, Ram head Mike Manley talked loyalty, conquest and the brand's next five years. Look for models like the Ram 1500 TRX, new versions of the Ram Heavy Duty and increased electrification and autonomy. At FCA's last five-year extravaganza, we heard a lot of grand plans for Ram. Unlike a lot of things from other brands at that presentation, most of Ram's products hit the market, though not as soon as FCA would have liked. Still, things are looking positive for the automaker. While the product line isn't going to expand much in the North American market, FCA plans to expand the Ram nameplate to new markets worldwide. We'll see finally see new versions of the Ram Heavy Duty at the 2019 Detroit Auto Show. FCA promises the new truck will have the segment's most powerful diesel engine. By 2022, we'll see the debut of the production version of the Ram TRX, a performance-focused truck that should go head-to-head with the Ford F-150 Raptor. Related Video:
