The Hyundai M6VR2 6-speed manual transmission is slated for use in the export version of the Kia Tasman, with production scheduled for 2025. This choice reflects the transmission’s proven reliability and performance in handling engines that produce significant torque—rated up to 392 Nm (40 kgm; 289 lbf-ft).
The 2.2 L diesel engine in the Tasman is anticipated to benefit from the transmission’s close-ratio design, which supports efficient power delivery and improved fuel economy during prolonged, heavy-duty operation, while the use of cable-controlled shift mechanisms in the M6VR2 ensures precise gear selection.
In this application, the M6VR2 is expected to deliver a balance between responsive shifting and robust durability, which is particularly important for the Tasman’s dual-purpose in both commercial and private use.
Technical Specifications
- MTF Standard:
Adheres to standard MTF requirements, ensuring consistent performance across models. - Viscosity:
Originally specified as SAE 75W-85, the requirement has been updated to SAE 70W to support improved lubrication and reduced friction. - Grade:
Utilises API GL-4 grade oil, a common standard in manual transmissions for reliable operation under varying loads. - Shift Control:
Features cable-controlled shift mechanisms, providing precise gear selection. - Gear Oil Capacity:
The M6VR2 requires 2.2 L of gear oil, compared to 2 L for its predecessor, the M6VR1. This increase allows for enhanced lubrication and thermal management.
Historical Development and Model Applications
Genesis Coupe
- Initial Models:
The first Genesis Coupe models were equipped with the M6VR1 for Theta engine vehicles and the M6VR2 for Lambda engine vehicles. - Facelift Models:
Later models standardised on the M6VR2 across both engine variants, reflecting its improved performance and durability.
Other Applications
- Grand Starex:
With the launch of the Euro 5-compliant A2 engine in January 2012, the M6VR2 was adopted for the Grand Starex to meet updated emissions standards while maintaining performance. - Genesis G70 2.0T (US Model):
The initial US model of the Genesis G70 2.0T, particularly in sports trim, was fitted with the M6VR2. - Kia Tasman:
The transmission is scheduled to be installed in the export version of the Tasman 2.2L diesel in 2025, following the discontinuation of the Grand Starex in 2021 for domestic use.
Gear Ratios and Comparative Data
The following table summarises the gear ratios for different vehicle applications using the M6VR2:
| Vehicle/Model | 1st | 2nd | 3rd | 4th | 5th | 6th | Reverse | Final Drive |
|---|---|---|---|---|---|---|---|---|
| Hyundai Genesis Coupe 3.8L / Genesis G70 | 3.848 | 2.317 | 1.623 | 1.233 | 1.000 | 0.794 | 3.985 | 3.538 |
| Hyundai Starex (TQ) 2.5L | 4.489 | 2.337 | 1.350 | 1.000 | 0.784 | 0.679 | (Not specified) | 4.253 |
These ratios are engineered to offer a balance between acceleration and cruising efficiency. The close-ratio design is particularly beneficial in performance models such as the Genesis Coupe and Genesis G70, while the adjustments in the Hyundai Starex cater to the additional torque requirements of heavier vehicles.
Summary of Key Points
- The M6VR2 is rated for up to 40 kgm of torque and utilises API GL-4 oil with an updated SAE 70W viscosity.
- It employs cable-controlled shift mechanisms and requires a gear oil capacity of 2.2 L.
- Initially deployed in Genesis Coupe models, the transmission has been used in various Hyundai and Kia vehicles, including the Grand Starex and Genesis G70 2.0T.
- It is scheduled for installation in the export version of the Kia Tasman 2.2L diesel in 2025.
