The introduction of a plug-in hybrid electric vehicle (PHEV) to the updated Range Rover line-up follows the announcement last week of the Range Rover Sport PHEV, which uses an identical powertrain.
The two models now spearhead the Jaguar Land Rover plan to have an electrified version of every model on sale by 2020.
The updated Range Rover, which rivals the Mercedes-Benz GLS and Bentley Bentayga, also gets an overhauled interior to bring it into line with the Velar and a new range-topping SVAutobiography Dynamic. Gerry McGovern, Land Rover's design director, said of the new cabin: "This interior is a revelation, rest assured".
The most powerful production Range Rover yet, the SVAutobiography Dynamic uses a 5.0-litre supercharged petrol V8 with 557bhp, a 15bhp increase over its predecessor, and has 516lb ft of torque. It covers 0-62mph in 5.4sec, 1.4sec slower than the W12-powered Bentayga.
Created by JLR’s Special Vehicle Operations, the range-topper has a new chassis calibration to optimise performance as an alternative to the standard Comfort mode. This lowers the ride height by 8mm and is designed to “heighten driver engagement without compromising comfort”, according to the firm.
The flagship model also gets an exclusive mesh grille design with chrome inserts and a revised rear bumper with integrated metal tailpipes.
The new Range Rover P400e PHEV combines a 296bhp 2.0-litre four-cylinder Ingenium petrol unit with a 114bhp electric motor, offering a total output of 398bhp available through the permanent four-wheel-drive system. It delivers 0-62mph in 6.8sec and a top speed of 137mph. On the combined cycle, it emits 64g/km of CO2 and achieves 101mpg.
The P400e, which is offered in both standard and long-wheelbase styles, replaces the SDV6 Hybrid Diesel powertrain that was previously offered.
