1. The A70 (Mk3) Supra: A Powerful Start (1986-1992)

The third-generation Supra, known as the A70 or Mk3, marked a significant shift, becoming a standalone model separate from the Celica. It introduced a new level of performance for Toyota.

Engine Options: The Mk3 predominantly featured the 7M-GE (naturally aspirated) and the more sought-after 7M-GTE (turbocharged) inline-six engines.
Horsepower Figures:
- 7M-GE (Naturally Aspirated): Typically around 200 horsepower.
- 7M-GTE (Turbocharged): This is where the Mk3 started to flex its muscles, initially producing around 230 horsepower (USDM specs). Later revisions saw slight bumps, keeping it firmly in the performance car category of its era.

2. The A80 (Mk4) Supra: The Legend is Born (1993-2002)

This is arguably the Supra most people envision when they hear the name – the car that starred in movies and became a tuning icon. The A80 Supra is famous for its 2JZ engine, known for its incredible strength and tunability.

Engine Options: The Mk4 offered two main engine choices: the 2JZ-GE (naturally aspirated) and the revered 2JZ-GTE (twin-turbocharged).
Horsepower Figures:
- 2JZ-GE (Naturally Aspirated): Generally produced around 220 horsepower.
- 2JZ-GTE (Twin-Turbocharged, USDM): This is the big one! For the U.S. market, the twin-turbo A80 Supra was rated at an impressive 320 horsepower.
- 2JZ-GTE (Twin-Turbocharged, JDM): Due to a “gentlemen’s agreement” among Japanese manufacturers at the time, the Japanese domestic market (JDM) twin-turbo models were officially rated at 280 PS (approximately 276 horsepower). However, many enthusiasts believe they were conservatively rated and often produced similar real-world power to their USDM counterparts.

3. The A90/A91 (Mk5) Supra: A Modern Comeback (2020-Present)

After a long hiatus, the Supra returned in 2020, developed in collaboration with BMW. While it features a BMW-sourced engine, it still carries the Supra spirit.

Engine Options: The Mk5 is offered with two main BMW-derived engines:
- The B58 3.0-liter turbocharged inline-six cylinder engine.
- The B48 2.0-liter turbocharged four-cylinder engine.
Horsepower Figures:
- B58 (3.0L Inline-Six):
  - Initial 2020 Models (USDM): Officially rated at 335 horsepower. However, dyno tests often showed these engines producing significantly more wheel horsepower than advertised, leading to speculation that Toyota’s official number was understated.
  - 2021+ Models (USDM): Toyota officially upgraded the rating to a robust 382 horsepower. This revision included some engine component changes, and once again, dyno results frequently show these models producing even higher numbers at the wheels.
- B48 (2.0L Four-Cylinder): This lighter, more agile option typically produces around 255 horsepower.

Why the Numbers Change: Factors Affecting Supra Horsepower

As you can see, there’s no single answer to “How much horsepower does a Supra have?” Here’s why those numbers fluctuate:

Engine Type: Naturally aspirated engines will always produce less power than their turbocharged counterparts from the same era.
Market/Region: Different emission regulations and local market agreements (like Japan’s “gentlemen’s agreement”) can lead to different official horsepower ratings for the exact same engine in different countries.
Model Year Updates: Manufacturers often make revisions to engines throughout a model’s lifecycle, leading to official power bumps, as seen with the Mk5 Supra.
Modifications (The “Wild Card”): This is crucial for Supras! Many owners heavily modify their cars, especially the Mk4 and now the Mk5. A highly tuned Supra can easily double or even triple its stock horsepower, reaching well over 1000 horsepower in extreme cases.

How to Confirm a Supra’s Horsepower (Step-by-Step Guide)

If you’re looking at a specific Supra and want to know its stock horsepower, follow these steps:

Step 1: Identify the Generation.
* Is it an A70 (Mk3), A80 (Mk4), or A90/A91 (Mk5)? This is usually obvious from its exterior design.

Step 2: Determine the Model Year.
* For the Mk5 especially, the model year can mean a difference of nearly 50 horsepower. For the Mk4, it helps differentiate between early/late production, although the power didn’t change as drastically.

Step 3: Check the Engine Type (if possible).
* Is it naturally aspirated (NA) or turbocharged (T/TT)? For Mk4s, the turbo models often have “Turbo” badging. For Mk5s, distinguish between the 2.0L four-cylinder and the 3.0L six-cylinder.
* Tip: If you’re looking at an official spec sheet, the engine code (e.g., 2JZ-GTE, B58) will tell you everything you need to know.

Step 4: Consult Reliable Sources for Stock Specifications.
* Owner’s Manual: If you have access to it, this is the most accurate source for that specific vehicle.
* Official Toyota Specifications: Check Toyota’s historical data or current model specifications on their official website.
* Reputable Automotive Databases: Websites like Edmunds, Kelley Blue Book, or major automotive review sites (e.g., Car and Driver, MotorTrend) provide verified factory specifications.
* Avoid forums or unofficial fan sites for initial verification of stock numbers, as they can sometimes contain anecdotal or incorrect information.

Step 5: For Modified Cars, Demand Proof.
* If a seller claims a Supra has significantly more than stock horsepower, always ask for recent dyno sheets to verify their claims. “Trust, but verify” is key here!

Tips for Understanding Supra Horsepower

Crank HP vs. Wheel HP: Manufacturers (like Toyota) almost always quote crank horsepower (bhp or hp), which is the power measured at the engine’s crankshaft. A dyno, however, typically measures wheel horsepower (whp), which is the power that actually reaches the wheels after experiencing drivetrain loss (friction, heat, etc.). Wheel horsepower is usually 10-20% lower than crank horsepower. So, a 320hp Mk4 Supra might only put down 280-290whp on a dyno.
Horsepower vs. Torque: While horsepower sells headlines, torque is what you feel when you accelerate. Horsepower is about how fast work can be done, while torque is the twisting force itself. A good balance of both leads to an exhilarating driving experience. Supra engines, especially the turbocharged ones, are renowned for their healthy torque figures.
The 2.0L Mk5 is Still a Supra: Don’t dismiss the four-cylinder Mk5 Supra. While less powerful than its six-cylinder sibling, its lighter weight makes it incredibly agile and a fantastic driver’s car in its own right, especially for those who prioritize handling.

Common Mistakes to Avoid

Assuming All Supras Have 320hp: This is a common misconception often linked to the Mk4 twin-turbo model. As we’ve seen, many Supras have significantly different power outputs.
Confusing Crank HP with Wheel HP: Remember the difference! A car dynoing at 300whp is very powerful, even if its official crank rating is higher.
Believing Unverified Claims for Modified Cars: Just because someone says their Supra makes 800hp doesn’t mean it’s true. Always ask for dyno sheets or other verifiable proof.
Ignoring the Market/Region for A80s: Remember the JDM 280 PS vs. USDM 320 hp distinction for the Mk4 twin-turbo.
Not Considering the Model Year for Mk5s: The 2021+ Mk5s received a significant official horsepower bump compared to the initial 2020 models.

Conclusion

The Toyota Supra truly is a magnificent machine, and its horsepower journey is as fascinating as its legacy. From the potent 230hp of the Mk3 to the legendary 320hp of the Mk4, and the modern, underestimated 382hp of the Mk5, each generation has pushed the boundaries of performance.

FAQ

Q. What is the stock horsepower of the latest generation (A90/A91) Toyota GR Supra?
A. The horsepower of the latest GR Supra depends on the model year and engine. The 2020 3.0L turbocharged inline-six (B58 engine) was officially rated at 335 hp. For the 2021 model year and onwards, Toyota upgraded the 3.0L engine, increasing its official output to 382 hp and 368 lb-ft of torque in North America. There is also a 2.0L turbocharged inline-four option available, which produces 255 hp.

Q. How much horsepower did the iconic Mk4 (A80) Toyota Supra, specifically the 2JZ-GTE twin-turbo, have from the factory?
A. The Mk4 Supra with the 2JZ-GTE twin-turbo engine, produced from 1993 to 2002, had varying official horsepower figures depending on the market. In the Japanese domestic market (JDM), it was rated at 276 hp (280 PS) due to a voluntary “gentleman’s agreement” among Japanese manufacturers. However, export models sold in the US and Europe had a more accurate rating of 320 hp (324 PS) for the twin-turbo variant. The naturally aspirated 2JZ-GE engine produced around 220 hp.

Q. Is there a significant difference in horsepower between the 2.0L and 3.0L GR Supra models?
A. Yes, there is a substantial difference. The 2.0L GR Supra, powered by a turbocharged inline-four engine, delivers 255 hp and 295 lb-ft of torque. In contrast, the 3.0L GR Supra, equipped with its turbocharged inline-six (B58) engine, produces 382 hp and 368 lb-ft of torque (for 2021+ models; 335 hp for 2020 models), making it significantly more powerful.

Q. Does the advertised horsepower of a Supra always equate to its actual power at the wheels?
A. No, advertised horsepower figures (often referred to as brake horsepower or BHP) are typically measured at the engine’s crankshaft. When power is transmitted through the drivetrain (transmission, differential, axles, etc.) to the wheels, there is an inevitable loss due to friction and other factors. This “drivetrain loss” can range from 10-20%, meaning a Supra advertised at 382 hp might register closer to 320-350 hp at the wheels on a dynamometer (wheel horsepower or WHP), depending on the specific vehicle and dyno conditions.

Q. How much horsepower can a Supra typically achieve with common aftermarket modifications?
A. Both the Mk4’s 2JZ-GTE and the A90/A91’s B58 engines are renowned for their incredible tunability. The 2JZ-GTE can often reach 500-600+ hp with an upgraded single turbo, improved fuel system, and ECU tuning while retaining much of its stock internal components. Similarly, the B58 in the GR Supra can also achieve 500-600+ hp with relatively simple modifications like a downpipe, upgraded intake, and a performance tune (often called “Stage 2” or “Stage 3” tunes), demonstrating their high potential for power gains.

Q. What were the horsepower ratings for the Mk3 (A70) Toyota Supra?
A. The Mk3 Supra, produced from 1986 to 1992, offered several engine options with varying horsepower. In North America, the most powerful engine was the 7M-GTE turbocharged inline-six, which initially produced 230 hp (1987-1988) and was later increased to 232 hp (1989-1992). Naturally aspirated versions (7M-GE) typically produced around 200 hp. Later Japanese market models also featured the twin-turbo 1JZ-GTE engine, rated at 276 hp.

Q. What is the highest horsepower ever recorded for a heavily modified Supra?
A. Highly modified Supras, particularly the Mk4 (A80) with its legendary 2JZ-GTE engine, have achieved phenomenal horsepower figures in specialized builds. With extensively built engines, massive turbochargers, custom fuel systems, and advanced tuning, some drag-racing oriented 2JZ Supras have surpassed 2,000 horsepower at the wheels, making them among the most powerful street-derived engines in motorsports history. The newer B58 engine in the A90/A91 GR Supra is also seeing builds pushing well over 1,000 hp.
