What is the top speed of the Toyota GT86 without limiter?
The Toyota GT86’s electronic limiter typically keeps top speed around 140 mph (about 225 km/h). If the limiter were removed, a theoretical maximum would be higher, estimated around 155–162 mph (250–260 km/h) under ideal conditions. Real-world results vary with model year, drivetrain, tires, and atmospheric conditions.
Official limiter and its role
The GT86 is tuned to prioritize balanced performance and safety; the electronic limiter is designed to prevent the car from reaching velocities that could compromise handling or tire integrity. In most markets and model years, the limiter sits around 140 mph (225 km/h).
Notes on market differences
Some regions or model years may have slight variations in indicated top speed due to tuning, emissions, or performance packages. The automatic and manual transmissions may also produce minor differences, generally within a few km/h.
Estimating a limiter-free top speed
Estimating the top speed without a limiter is inherently theoretical. It depends on engine power, aerodynamics, gearing, and tires, among other factors. Here are the major considerations.
- Engine power at redline and drivetrain losses: The FA20 engine produces around 200 horsepower; without the limiter, you could use peak crank power, but horsepower at the wheels is reduced by the transmission and differential losses.
- Aerodynamics and CdA: The GT86 has a relatively low drag coefficient for a small sports car, but at high speeds drag increases with v^3, limiting top speed.
- Gearing and final drive: The top speed depends on the overall gearing; even with maximum power, a tall top gear and final-drive ratio cap the achievable speed.
- Tire width, grip, and temperature: Tires must handle the load and heat at high speeds; insufficient grip will prevent reaching theoretical top speed.
- Environmental conditions: Air density, wind, temperature, and altitude affect speed; high altitude or headwinds reduce top speed.
- Mechanical reliability: Pushing beyond the limiter can stress components; fuel trims and engine protection systems might intervene in some conditions.
Under ideal conditions, a limiter-free GT86 might approach around 250–260 km/h (155–162 mph). Actual results would vary and removing the limiter is not recommended for road use.
Safety, legality, and practicality
Attempting to remove a vehicle's electronic limiter is unsafe and often illegal for street use. It may void warranties and could affect insurance coverage. Any modifications should be performed by qualified professionals and tested in controlled environments.
Summary
Bottom line: the Toyota GT86 is electronically limited to about 140 mph (225 km/h) in standard form. Theoretical, limiter-free speed estimates put the figure in the 250–260 km/h (155–162 mph) range under ideal conditions, but real-world results depend on many factors and removing the limiter is not advisable.
How to remove speed limiter on GR86?
The speed limiter can be canceled by operating only the vehicle speed pulse signal from the signals in the CAN communication. (There is no secondary negative effect concerned with releasing the speed limit.)
How fast can a GT86 go?
As the testing happened in the unrestricted sections of the Autobahn, the driver in the video above tried to reach the coupe's claimed top speed, which is around 140 miles per hour (226 kilometers per hour) – a respectable top speed for a car in this price range.
How fast can a Toyota GR-86 go?
The top speed for the Toyota GR86 is an electronically limited 140 mph, regardless of whether it has a manual or automatic transmission. This is the standard top speed for the current generation of the car.
- Top speed: 140 mph (electronically limited)
- 0-60 mph: Around 6.1 seconds for the manual and 6.6 seconds for the automatic
- Engine: 2.4L flat-four boxer engine producing 228 horsepower and 184 lb-ft of torque
