What transmission does the new generation Sagitar use?
3 Answers
Sagitar uses a 6AT transmission. The transmission is a mechanism used to change the speed and torque from the engine, capable of fixed or stepped changes in the transmission ratio between the output and input shafts. Taking the 2021 Sagitar as an example, its body dimensions are: length 4753mm, width 1800mm, height 1462mm, wheelbase 2731mm, fuel tank capacity 50L, trunk capacity 553L, and curb weight 1355kg. The 2021 Sagitar features a front McPherson independent suspension and a rear multi-link independent suspension. It is equipped with a 1.2L turbocharged engine, delivering a maximum horsepower of 116PS, maximum power of 85kW, and maximum torque of 175Nm.
Last month I test drove the 2023 Sagitar, which mainly uses Volkswagen's 7-speed dry dual-clutch transmission, model named DQ200. This transmission is paired with both the 1.2T and 1.5T engines, delivering exceptionally crisp gear shifts. When you step on the accelerator, the downshifts are lightning-fast, making highway driving particularly thrilling. However, during morning and evening rush hour traffic, there's occasionally a slight jerk when shifting from second to first gear, like a gentle nudge in the back. After driving it for a week, I was pleasantly surprised by the fuel consumption—just 7.5L/100km in city driving, much more economical than my old 6AT car. I heard this transmission uses new material clutch plates with significantly improved heat dissipation, so there's no need to worry about overheating even on long trips.
From a transmission technology perspective, the DQ200 dual-clutch design in the Sagitar is quite ingenious. It utilizes two separate clutches to control odd and even gears respectively. While the current gear is engaged, the next gear is already pre-selected, enabling gear shifts in just 0.2 seconds. The dry structure operates without oil immersion, relying on air cooling for heat dissipation, achieving a transmission efficiency of up to 96% - making it more fuel-efficient than wet dual-clutch systems. However, the gear set requires extremely high precision, with metal fatigue tests indicating a clutch plate lifespan of approximately 150,000 kilometers. Volkswagen has reinforced this transmission with a hydraulic support structure, reducing vibration over speed bumps by 30% compared to earlier models. Nevertheless, it's recommended to switch to S mode during prolonged traffic congestion to minimize semi-engagement wear.
