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.

These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.

2020 Ram Heavy Duty Limited Black Edition answers the call of the void

Ram buyers overcome by the lure of the Sith or the call of the void when configuring their pickups have had a variety of ways to go dark on their trucks, from 1500 to the heavy duty line. Now the 2020 Ram 2500 and 3500 HD's top Limited trim is getting access to all the darkness possible with the Black Edition, creating a truck that says "lights out" in about six different ways. The package blacks out the heavy duty rigs entirely, starting with the black grille with black RAM lettering, black bumpers front and back, black tow hooks, black door handles, black side-view trailer tow mirrors, black bezels around the LED headlights and taillights, dark-tinted taillights, and matte badges. Any colored lenses, such as the clearance lights above the cab, are clear. Because on the Ram Heavy Duty Black Edition, black means black. The Black Edition can be optioned on the Ram 2500 or 3500 in 4x2 or 4x4, in single- or dual-rear-wheel trims. When outfitted with single wheels in back, the Black Edition sits on 20-inch black wheels. When dual wheels hang off the back axle, buyers will find 17-inch black wheels with machined eyelets. Engine choices are the regular trio of 6.4-liter Hemi V8 with 410 horsepower and 429 pound-feet of torque, the normal 6.7-liter Cummins straight-six diesel making 370 hp and 850 lb-ft, or a high-output version of the 6.7-liter restricted to the 3500 that puts out 400 hp and 1,000 lb-ft. The three-quarter- and one-ton darkness rolls into dealerships in a few months starting at $64,440 for the Ram 2500 2,745 after a $1,695 destination charge. That's a $1,095 premium over the standard Limited Trim. Assuming the same premium for the Ram 3500 Black Edition means a starting price of $65,790. Related Video:
