T1

The T1 platform debuted in 2006 with the 2007 model year Ford Expedition, and shares elements with the 2004–2008 Ford F-150's chassis. For the 2007 model year, the Lincoln Navigator moved to the T1 as well.

The fourth generation Expedition, Expedition Max, Navigator and Navigator L are also built on this platform, shared with the Ford F-Series thirteenth generation chassis design from the P552 F-150 and P558 Ford Super Duty.

T5

The T5 platform is what Land Rover calls an Integrated Body Frame, which joins both a monocoque section for the engine bay and passenger compartment, and a ladder frame section for the gearbox and suspension. Compared to the all unibody 2001 Range Rover, the heavier frame construction was chosen for lower costs, with the intent to use it on a new redesigned Defender and various other models, but many of these plans did not transpire.

2004–2009 Land Rover Discovery 3 / Land Rover LR3 - Use of the 2002 Ford Explorer's chassis was considered, but ruled out over unfavourable off-road clearances.
2006–2013 Range Rover Sport
2010–2016 Land Rover Discovery 4 / Land Rover LR4

Cancelled models:
