The LC500 GT500 car made its début at the 2017 Okayama GT 300km, [40] and claimed 14 race wins of the 24 overall entered races from 2017 until 2019 (26 with the Super GT/DTM crossover events). In 2020, with the introduction of the new Class One and the revival of the Supra nameplate, the Toyota GR Supra would take its place in the GT500 category.
This formula assumes that any hub gear is in direct drive. A further factor is needed for other gears (many online gear calculators have these factors built in for common hub gears). For simplicity, 'gear inches' is normally rounded to the nearest whole number. For example, suppose the drive wheel is actually 26 inches in diameter.
The rotational speed of the wheels for that given forward speed is simple to calculate, being the tire circumference multiplied by the RPM. [a] As the tire RPM at maximum speed is not the same as the engine RPM at that power, a transmission is used with a gear ratio to convert one to the other. [b]
One standard option for the Brompton folding bicycle is to use a 3-speed hub gear (roughly a 30% difference between gear ratios) in combination with a 2-speed derailleur gear (roughly a 15% difference) to give 6 distinct gear ratios; this is an example of half-step gearing. Some Brompton suppliers offer a 2-speed chainring 'Mountain Drive' as ...

A mechanical transmission with a selection of different gear ratios is designed to make satisfactory power available over the full range of vehicle speeds. The goal of the selection of gear ratios is to keep the engine operating in its power band. The narrower the band, the more gears are needed, closer together in ratio.
Toyota Motor Corporation's L-series of HybridSynergyDrive (HSD) transmissions (not to be confused the 4 and 5 speed manual L-series Toyota transmissions) are hybrid gearboxes containing 2 electric motors, one for driving the wheels and one for controlling the ratio between the engine and the electric drive motor, as well as an optional 2 or 4 speed planetary transmission attached to the end of ...
Bore and stroke is 94 mm × 102 mm (3.70 in × 4.02 in), it produces 381 hp (284 kW; 386 PS) @ 5,600 rpm and 55.4 kg⋅m (401 lb⋅ft; 543 N⋅m) of torque @ 3,600 rpm, with a compression ratio of 10.2:1. A stainless steel exhaust manifold incorporating a 3-way catalytic converter is used. The maximum engine speed is 6,000 RPM.
