英文解释：A unit with a planetary gearset which turns the driveshaft faster than the transmission output shaft.
An additional gearbox which is mounted in the driveline. Normally the final drive ratio is 1:1; but the overdrive makes it less (e.g., 0.87:1). The overdrive can reduce gas consumption at sustained high-speed driving, engine noise, and engine wear. Also called "overdrive transmission." Also see aftermarket overdrive
Gearing in which less than one revolution of a transmission's input shaft causes one turn of the output shaft. The purpose of overdrive is to reduce engine rpm in high gear for better fuel economy. Example: A transmission with an overdrive top gear has a ratio of 0.70 to one. Turning the input shaft 0.7 revolutions causes 1.0 revolution of the output shaft.

High-performance 626 MPS GT is test-bed for sports tuning ideas
A high-performance, twin turbo, four wheel drive, concept version of Mazda's popular 626 saloon has made its debut at the Geneva Motor Show.
Created as a test-bed for sports tuning parts and designated 626 MPS GT-"Mazda Performance Series" - it has been developed to bring out thefull potential of the 626 and to meet a growing demand forhigh-performance four-door saloons.
Based on the technologies developed by Mazda Motor Corporationaffiliate Mazda Speed, the 626 MPS GT will also be assessed for itsproduction potential.
While the car retains the functional and stylish lines of the recentlyre-launched 626 design, the 626 MPS GT has been radically transformed intoa powerful and sporty performance car.
The exterior gains a more dynamic presence with the use of a largerrear spoiler - which provides down-force to aid traction for the reartyres - plus front spoiler, side skirt, over-fender and oversizealuminium wheels. These items not only add to the appearance but alsosignificantly enhance the car's aerodynamic and cooling performance.
The interior has white instrument faces, special seats and aluminiumpedals. Despite the sporting nature of the 626 MPS GT it also hasexceptional functionality, with a spacious luggage area, long loadcapability through the rear seats.
Modifications for enhanced performance include the use of a Twin-Turbowith Mazda's well-proven KL-ZE 2.5-litre V6 engine, plus increasedcapacity of the intercooler, radiator and oil-cooler.
Combined with special ECU and straight-through silencer, the 626 MPSGT generates maximum output of 206kW (280ps) at 6,500rpm and maximumtorque of 392N
