Introduction
The standard model Lotus Evora comes with the choice of 3 gearboxes, the standard 6-speed manual, the Close Ratio Gearbox - again a 6-speed manual but with a closer ratio gear set - and the Lotus IPS 6-speed automatic (this makes the car an Evora IPS).
All three of these gearboxes are Toyota sourced, with the IPS featuring Lotus's own electronic controls to make it more suitable for a sporting application.
For the manual gearboxes this is the Toyota EA60 gearbox, as fitted to the Toyota Auris 2.0 D-4D and 2.2 D-CAT models.1 These are diesel engines, and the standard ratios are as they in the Auris, possibly explaining why they are often seen as rather long. The closer ratio gear set appears to be a bespoke set of ratios unique to the Evora and Evora S.
This may be the Toyota U660E gearbox2 as this is used by Toyota in conjunction with the 2GR-FE engine in several vehicles and is a match for Lotus's quoted gear ratios. Unlike the manuals, cars fitted with the IPS gearbox do not have the engines rev limit increased to 7000rpm when in Sport Mode, as this would damage the gearbox.3
For the manual gearboxes Lotus list two final drive ratios, one for 1st through 4th gears and another slightly shorter ratio for 5th and 6th.4
The Evora S is not available with the IPS gearbox, and comes with the close ratio Sport Gearbox fitted as standard.
