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.

2018 Ford F-150 Powerstroke vs. 2018 Ram 1500 EcoDiesel: comparing the specs

Now that Ford has finally released specifications for its diesel Ford F-150, we can finally see how it stacks up against its sole competition, the Ram 1500 EcoDiesel. Naturally, since we haven't driven the new diesel F-150, we can't tell you which is better on the road, but there are interesting things we can glean from the numbers. Compare these and other potential new vehicle purchases using our tool. For one thing, the two trucks are extremely similar from a powertrain perspective. Both trucks use a turbocharged 3.0-liter V6 diesel, with the Ford using a 10-speed automatic, and the Ram using an 8-speed automatic. The Powerstroke engine is built in the U.K. but specifically tuned by Ford for American pickup truck duty. It is also is related to the diesel V6 used by Jaguar and Land Rover. The Ram 1500's engine is made by VM Motori. Only 10 horsepower and 20 pound-feet of torque separate the two, with the Ford getting the slight advantage. The Ford also produces its horsepower and torque slightly sooner than the Ram. Peak power in the Ford comes at 3,250 rpm compared to 3,600 rpm in the Ram, and peak torque arrives at 1,750 rpm in the Ford, and 2,000 rpm in the Ram.

The F-150 Powerstroke can carry 2,020 pounds of cargo, or tow 11,400 pounds. The Ram EcoDiesel, depending on configuration, can carry 1,100 to 1,600 pounds of cargo, and tow between 7,560 and 9,210 pounds. Fuel economy might go to the Ford if it hits the company's target of 30 mpg highway. That would beat the Ram's 27 mpg highway. We don't know what Ford's target city mpg is, but the Ram manages 20 in town with two-wheel drive. Four-wheel drive drops the city rating to 19 mpg. View 6 Photos The biggest decider between the trucks might be cost. Ford is only offering its diesel engine on higher end trims, which means that the cheapest diesel F-150 starts at $46,315. That's for a two-wheel drive Lariat extended cab with a 6.5-foot bed. Ram on the other hand, offers the diesel in everything from its ultra-bare-bones Tradesman pickup, allowing for a base price of just $28,585, up to the fancy Laramie Longhorn and Limited trims. Ram's diesel is also available with all cab variants, while Ford's is only offered in extended- and double-cab body styles.

2023 Ford F-150 Raptor R vs. 2022 Ram TRX | By the numbers

Ford has responded to the Ram 1500 TRX with its own supercharged supertruck: the brand-new 2023 Ford F-150 Raptor R. Ford may be late to the party, but fans can rest assured that its 5.2-liter supercharged V8 is ready to throw down, packing 700 horsepower in a leaner, more-focused package. You can read all about the new Raptor R in our debut write-up, but if you're curious how it stacks up to the TRX by some of its key metrics, you're in the right place. Let's get started.  Performance Let's go ahead and get this one out of the way. Both of these trucks offer blistering performance figures, but a quick glance at the specs suggests a clear winner. Both the Ford and Ram are half-ton crew cab pickups powered by supercharged V8s, but how that package comes together differs pretty significantly between the two.  2023 Ford F-150 Raptor R Engine: 5.2-liter supercharged DOHC V8 Power: 700 horsepower Torque: 640 pound-feet Suspension: Independent double-wishbone (front); five-link coil with Panhard rod (rear); continuously variable active Fox dampers (both) Curb Weight: 5,950 pounds 2022 Ram 1500 TRX Engine: 6.2-liter supercharged OHV V8 Power: 702 horsepower Torque: 650 pound-feet Suspension: Independent double-wishbone (front); five-link coil with track bar (rear); active Bilstein dampers (both) Curb Weight: 6,395 pounds Conclusion It was looking good for the TRX right up until the end there. Ram has the edge in total power and torque — just barely — but that advantage disappears when you consider the TRX's extra heft. 400 pounds may not seem like the end of the world in the context of these trucks, but weight plays a roll in all aspects of performance. This looks like a home run for the Blue Oval.  Off-road Raptor was the default half-ton performance truck for many years, but with OEMs getting ever more serious about building full-size pickups that can take a beating off-pavement, Ford has leaned harder into the Raptor's high-speed performance. Ram's approach was similar, only with more power — until now, that is. But there's more to off-roading than blasting across the desert.
