How does the new 1.5L TGDi engine compare to the 1.8L?

Question

Accepted Answer

The New 1.5L TGDi Engine Offers Comparable Power with Enhanced Efficiency and Reduced Weight

The new 1.5-litre 3-cylinder TGDi engine option for the Proton X70 delivers a robust 177PS (175hp) and 255Nm of torque, closely matching the 1.8-litre 4-cylinder TGDi engine's output of 184PS (181hp) and 300Nm of torque. A key advantage of the smaller engine is its ability to reach peak torque earlier, at 1,500rpm compared to the 1.8L's 1,750rpm, and it contributes to a notable 7 per cent reduction in urban fuel consumption. Furthermore, the 1.5L TGDi engine reduces the vehicle's kerb weight by 50kg, enhancing overall efficiency.
Performance Metrics and Torque Delivery

The 1.5L TGDi engine produces 177PS (175hp) and 255Nm of torque, positioning it as a potent unit within its class. While the 1.8L TGDi engine offers slightly more power at 184PS (181hp) and a higher torque figure of 300Nm, the 1.5L achieves its maximum torque at a lower engine speed. This earlier torque delivery, commencing at 1,500rpm versus the 1.8L's 1,750rpm, can translate to a more responsive feel in typical driving conditions. The performance difference in horsepower is minimal, with the 1.5L engine producing only 6 horsepower less than its larger counterpart.
Fuel Efficiency and Weight Reduction

A significant benefit of the new 1.5L TGDi engine is its improved fuel economy. Proton estimates a 7 per cent reduction in fuel consumption within the urban driving cycle when equipped with this engine. This enhanced efficiency is partly attributed to the engine's lighter construction; the 1.5L TGDi engine contributes to a 50kg reduction in kerb weight compared to the previous X70 2020 1.8 Standard model. This lower weight, combined with the engine's inherent efficiency, is expected to further bolster its economic advantages.
Class-Leading Power and Competitive Positioning

The 1.5L TGDi engine is presented as a highly competitive offering in its segment, demonstrating superior performance against other 1.5-litre turbocharged engines. For instance, it significantly outperforms the BMW 218i Grand Coupe M Sport, which produces 138hp and 220Nm of torque. This comparison highlights the 1.5L TGDi's strong power and torque output, making it a standout option for drivers seeking both performance and efficiency in a compact SUV engine.
