With the sky rocketing fuel prices, which are the cars that are achieving the best mileage per KM, pls specify whether it is diesel or Petrol so that we can compare easily.

I will start. I have often used a leased 2700cc petrol VVTI and the efficiency is about 7km/Litre in town. Not bad for such a huge engine i suppose.

T Prius will comfortably give you 35km/l; the best deal out there

Let's answer Injere based on practical experience, not googled up data sheets. I did Kakamega and back in a Toy fielder over Christmas. Average 12.85 Km per liter

I regularly keep stats on fuel consumption on a 2L 2000 D4 auto premio. Best consumption has been a trip down to Msa where I got just under 16 km/l while driving mostly under the speed limit (100kph). Town driving of course gets stuff like 9-10 km/l depending on how much jam there is.

-> Driving style/habits play a major part in how much/little your car uses.
- Optimal speed also depends on the size of the engine.

From my googling online the diesels (TDIs, CDIs etc) look a good better for great consumption long term but would like some real life *Kenyan* practical experience from the guys with them. I'm told our diesel is not clean enough, even if Low Sulphur Diesel (500ppm sulphur content) is available.
