The Tomcar Diesel engine has a slower top speed (65 kph) than the petrol engine, and also lower acceleration. However, if you feel that your diesel engine is lacking power, it may point to other problems. Check the following:
1. Diesel Bug!
Diesel bug is insidious. It eventually blocks fuel filters which leads to fuel starvation and inevitably, engine failure. Read our complete article on Diesel Bug here.
The issue may be with the CVT (learn how the CVT system works here).
Also check that the drive belt is not slipping - see full article here.
If the problem persists, please contact Tomcar Support.
