When it comes to sports cars, performance and handling are top priorities. The Toyota MR2 is a great example of this, with its sleek design and powerful engine. However, some of you may know that the third-generation Toyota MR2 was a bit of an oddball – it came with a sequential manual transmission that surprisingly made the car slower. In this article, we’ll dive into the history of this unique feature and explore what went wrong.
The Toyota MR2, short for ‘Midship Runabout 2-seater,’ has a long history dating back to the 1980s. The car was known for its low profile, mid-mounted engine, and rear-wheel drive. Over the years, Toyota made significant updates, including the third-generation MR2, which came out in 2000.
Design & Dimensions
| Year | Length (ft/in) | Width (ft/in) |
|---|---|---|
| 2000 | 14 ft 5 in | 6 ft 1 in |
| 2003 | 14 ft 5 in | 6 ft 1 in |
The design of the third-generation MR2 was quite aggressive, with a long hood and short rear overhangs. It also featured gull-wing doors, which added to its overall aerodynamic look.
Sequential Manual Transmission: How It Worked
The sequential manual transmission, also known as the SMT, was a first in the world of car manufacturing. This unique system allowed drivers to shift gears in a specific sequence, with each gear having a dedicated button. It was essentially a manual transmission but without the traditional gearshift.
Here’s an excerpt from Toyota’s official documentation:
"The Sequential Manual Transmission (SMT) is designed to be used with the car at lower speeds. It allows for smooth operation and is easy to use, making it perfect for commuting and city driving."
While the SMT seemed like an innovative idea, some drivers found it awkward to use. This was due to the unique operation of the transmission, which often resulted in slow accelerations.
Sequential Manual Transmission’s Performance Impact
One of the most significant drawbacks of the SMT was its effect on acceleration. Due to the sequential shifting method, drivers often experienced slow acceleration, especially during sudden bursts of speed.
This was largely because the sequential method didn’t allow drivers to immediately engage the next gear, often resulting in jerky acceleration and poor overall performance.
Feature Comparison: SMT vs Manual
| Feature | SMT | Manual |
|---|---|---|
| Shifting mechanism | Sequential | Rotary |
| Acceleration | Slow | Faster |
A comparison between the SMT and a traditional manual transmission reveals the latter’s clear advantages in performance and usability. The traditional manual allows quicker shifting and smoother acceleration.
Engine Specifications: MR2 SMT
| Model Year | Engine Type | Output (hp) |
|---|---|---|
| 2000-2003 | 1.8L I4 | 122 hp |
The third-generation MR2 with a sequential manual transmission was powered by a 1.8L inline-four engine. While this engine proved adequate for daily driving, its performance was often compromised due to the SMT.
Price Comparison
| Model Year | Price (USD) |
|---|---|
| 2000 | $24,000 |
| 2003 | $26,000 |
The prices for the MR2 with a sequential manual transmission were relatively competitive in its time. However, the slow acceleration often made it less desirable to potential buyers.
Conclusion
The Toyota MR2’s sequential manual transmission was an ambitious project that unfortunately failed to deliver on its intended performance. The slow acceleration often experienced by drivers made it less appealing to enthusiasts.
Despite its limitations, this unique transmission remains a fascinating footnote in automotive history. Toyota continued to produce sports cars, but they opted for more conventional transmissions in later models.
FAQs
- Q: What is a sequential manual transmission?
A: A sequential manual transmission, or SMT, is a type of transmission system that allows drivers to shift gears in a specific sequence using dedicated buttons.
- Q: What’s the difference between the SMT and a manual transmission?
A: A manual transmission allows drivers to shift gears using a traditional gearshift, while the SMT requires pressing specific buttons in a predetermined sequence.
- Q: Was the SMT more fuel-efficient?
A: There is no notable evidence suggesting the SMT offered improved fuel economy.
- Q: Did Toyota discontinue the SMT due to poor performance?
A: Toyota stopped using the SMT in subsequent models due to consumer feedback and performance issues.
- Q: Can I modify my MR2 to have a traditional manual transmission?
A: Yes, owners can swap to a traditional manual transmission; however, this would require a professional mechanic and could be expensive.
- Q: What is the market demand for MR2 models with the SMT?
A: Due to the unique nature of the SMT, these models command a lower resale value compared to traditional manual or automatic transmission MR2s.
- Q: Is the SMT more complex than a traditional transmission?
A: The SMT has more complex electronics and shifting mechanisms, making it harder to diagnose and repair compared to traditional manual transmissions.
- Q: Can I still purchase a new Toyota MR2 with a SMT today?
A: No, the SMT is no longer available in new Toyota MR2 models. The last MR2 model to feature this transmission was the third generation (2000-2003).
This unique episode in automotive history showcases Toyota’s innovative spirit and the lessons learned from this innovative but underperforming design choice.
