A drivetrain (also frequently spelled as drive train or sometimes drive-train) or transmission system, is the group of components that deliver mechanical power from the prime mover to the driven components. In automotive engineering, the drivetrain is the components of a motor vehicle that deliver power to the drive wheels. [1]
The company converted a BMW car to prove viability. The BMW 530i gave double the MPG in city driving compared to the standard car. The test used the standard 3,000 cc engine. Petro-hydraulic hybrids allows downsizing an engine to average power usage, not peak power usage. Peak power is provided by the energy stored in the accumulator. [64]
The powertrain layout of a motorised vehicle such as a car is often defined by the location of the engine or motors and the drive wheels. Layouts can roughly be divided into three categories: front-wheel drive (FWD), rear-wheel drive (RWD) and four-wheel drive (4WD). Many different combinations of engine location and driven wheels are found in ...
Schematic diagram of rear-wheel Lexus Hybrid Drive transmission (L110/ L110F) In 2006 and 2007, a further development of the HSD drivetrain, under the Lexus Hybrid Drive name, was fitted to the Lexus GS 450h / LS 600h sedans as the L110 transmission.
Placing the engine near the driven rear wheels allows for a physically smaller, lighter, less complex, and more efficient drivetrain, since there is no need for a driveshaft, and the differential can be integrated with the transmission, commonly referred to as a transaxle. The front-engine front-wheel-drive layout also has this advantage.
The drivetrain design closest to RF in actual series production vehicles is the mid-engine, four-wheel-drive layout, typically seen in high end sportscar designs, and which, with the use of power-split centre differentials or hybrid drive systems, can be set up to send a variable amount of the total drive to the front wheels, in some cases up ...
In 1979, Toyota introduced and launched their first front-wheel-drive car, the Tercel, and it had its engine longitudinally mounted, unlike most other front-wheel-drive cars on the market at that time. This arrangement continued also on the second-generation Tercel, until 1987, the third generation received a new, transversely mounted engine.
While the mechanical layout of an FMR is substantially the same as an FR car, the classification of some models of the same vehicle may vary as either FR or FMR depending on the length of the engine (e.g. 4-cylinder vs. 6-cylinder) and its center of mass in relation to the front axle.
