TOTAL CONTROL
Range Rover Sport P400e vs
Porsche Cayenne E-Hybrid
On paper Land Rover’s Range Rover Sport HSE P400e and Porsche’s Cayenne
E-Hybrid have a lot in common. Both hybrid powertrains are similarly architect-
ed, with a small e-motor mounted between their internal combustion engines and
eight-speed transmissions.
Not all plug-in hybrids are created equal, however. The Porsche is much more
powerful, rocking a 335-hp, 2.9-liter, twin-turbo V-6 internal combustion engine
and a 134-hp e-motor. Total system output of 455 hp and 516 lb-ft of torque
shades the Range Rover’s 398 hp and 472 lb-ft.
The Range Rover carries a 13.1-kW-hr lithium-ion battery pack, while the
Porsche’s is a 14.1-kW-hr unit. Land Rover says the P400e will travel up to 31
miles on pure e-power, compared with the 27-mile range Porsche claims for the
Cayenne E-Hybrid.
But where the two PHEVs differ most is in the amount of control each allows the
driver to have over the hybrid powertrains. Land Rover only offers the choice of
preserving the existing state of charge in the battery to ensure the P400e can
operate in pure EV mode at a point in the future. Porsche allows the driver to get
much more involved.
