Like several of its predecessors, the X351 is available in both standard and long-wheelbase form, as well as many special editions. Engines are modern units already seen in other JLR products: the 5.0-litre petrol V8 either normally aspirated or supercharged, or a 3.0-litre diesel twin-turbocharged V6. For 2013, a 3.0-litre supercharged V6 was introduced to the line-up, primarily as an alternative to the diesel unit for improved fuel economy.
The X351 received a minor face lift in 2014, primarily upgrading the suspension and rear seat facilities on the long wheelbase versions, but also introducing small cosmetic changes across the range, and making stop-start technology standard on all engines.
