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.
JLR vehicle line director Nick Collins said: “[The PHEV] isn’t simply a no-compromise solution. It builds on the traditions of our flagship SUV and delivers heightened refinement and comfort with impressive performance and efficiency.”
The P400e offers two driving modes: the default Parallel Hybrid and EV.
Parallel Hybrid mode combines petrol and electric drive and allows the driver to optimise battery charge or fuel economy. It has a Save function that prevents the battery charge dropping below a selected level. A Predictive Energy Optimisation function requires you to enter a destination into the navigation system. The system, which is similar to that in many new plug-in hybrids such as the BMW 330e, then uses GPS altitude data to optimise the switch between electric motor and petrol engine, maximising fuel economy over different gradients.
