2019 Range Rover P400e Plug-In Hybrid

2019 Range Rover P400e Plug-In Hybrid

Until recently, the Range Rover stood as a seemingly impermeable bulwark against the very concept of downsizing. The physical scale of Land Rover’s flagship luxury SUV was imposing enough, but this was also matched by power plants that clearly equated bigger with better, intended for an ownership demographic with little concern about fuel costs. Sure, there have been diesel versions for some time, initially for European skinflints and also now in America, but the first full-size, gasoline Range Rover to use anything other than a V-8 appeared fairly recently, in 2012.

Now the supercharged 3.0-liter V-6 that understudies the current eight is being joined by an even smaller powerplant, one set to further trim the clan’s average cylinder count. Despite its muscular-sounding model designation, the new P400e, arriving in Europe at the same time as a lineup-wide facelift, uses an inline-four as its prime mover. This 296-hp version of Jaguar Land Rover’s Ingenium turbocharged 2.0-liter works in conjunction with a 114-hp electric motor integrated into the eight-speed automatic transmission, a powertrain the U.S. market will first see this summer in the smaller Range Rover Sport P400e. The combined output is 398 horsepower, more than either of the V-6 variants although still way short of the 518- and 557-hp supercharged V-8s. The more striking number is the one delivered by the 13.1-kWh lithium-ion battery pack that sits under the rear cargo floor: 31 miles. That’s Land Rover’s claim for pure-electric operation.

Several of the P400e’s other statistics seem flatly contradictory, although that’s largely due to the peculiarities of the European testing regime. The outright silliest is the score equivalent to 84 mpg on the EUDC consumption test, which is only possible because the assessment allows a plug-in hybrid to begin with its battery pack fully charged and finish with it fully depleted. That’s a bit like letting a standard combustion model get an undeclared top up from a jerrycan stashed in the back. For any journeys substantially beyond its electric range, Land Rover acknowledges that the P400e’s fuel economy is unlikely to prove better than that delivered by the Td6 diesel model; on the basis of trip-computer readings rather than brimmed tanks, real-world economy in the low-20-mpg range seems likely. A large percentage of the world’s Range Rover fleet, however, is used primarily for short journeys in close proximity to charging ports.

Attending Mass

Recharging the onboard battery pack entails opening a flap integrated into the radiator grille to access the plug. According to Land Rover, a 32-amp Level 2 connection can top off the electrons in 2 hours and 45 minutes, but times on a standard 120-volt supply will be far longer, at a claimed 14 hours. The sizable battery also adds mass, and we’re estimating a 5700-pound curb weight. According to Land Rover’s own figures, it’s 558 pounds heftier than the V-6 and 278 pounds more than the 518-hp V-8 edition. (The 557-hp V-8 model is only 27 pounds lighter than the P400e, Land Rover claims.)

Yet at lower speeds the powertrain ability to blend both gasoline and electrical power effectively disguises this increase in weight, and the P400e launches keenly as the motor lends its assistance (Land Rover claims a 6.4-second zero-to-60-mph time). Responses are also a measure snappier than in conventional Ranges, with the electric side of the powertrain filling the gap as the turbocharged engine spools up. While acceleration starts to fade as the P400e approaches triple-digit speeds—in marked contrast with the lesson in anti-physics that is the Range Rover Sport SVR—it still feels plenty quick. Refinement under everyday use is good, but the gasoline engine makes some inappropriately proletarian noises when pushed into the top quarter of its rev range. Far better to adopt a more relaxed pace and enjoy the near silent electric running that the car defaults to at low speeds.
