Can experts Tell me is this technical difficult, or it won't offer much savings on top of diesel ? Last time hard diesel saves fuel due to it generates high torque so can cruise at low rev n save fuel. But once hybrid suppose mostly on battery so torque from diesel has little help. Or other reasons ? Even if diesel has the low end torque which the electrics can substitute for, a litre of diesel is still more energy dense (by volume) than gasoline and thermal efficiency of diesel is still above petrol. And the electric motor is not always on, only mainly to help acceleration at low speeds, when cruising at 60 to 90kph its just the diesel engine doing its work at low revs. When accelerating from a stop, I guess the electric motor still helps because the engine doesnt need to boost so hard and run higher pressure so can keep the compression ratio of the engine higher (compared to a non hybrid diesel) and gain overall efficiency. Add in brake energy regen. Overall still gains in FC. Edited December 1, 2020 by Ake109 ↡ Advertisement 1 Link to post Share on other sites More sharing options...
Ake109 6th Gear December 1, 2020 Share December 1, 2020 (edited) 140i Auto, mixed driving with occasional lut. Based on car computer which i never reset over past 9.5k, average 9.4 litre/100km Based on pump tank and compare litres pumped vs odometer, range from 10 to 10.5km/litre Overall, better FC than expected for a 6 cyl turbo.

Stevekk Clutched December 1, 2020 Share December 1, 2020 (edited) 2009 Hyundai i30CW but mine is ~85% city and 15% highway. Having the same FC. Onboard trip meter. I know it’s not really accurate but should be somewhere around there. Edited December 1, 2020 by Stevekk Link to post Share on other sites More sharing options...
Philipkee Twincharged December 1, 2020 Share December 1, 2020 My new Honda city FC but I hardly rev and when I do manual calculation like distance travelled / fuel pumped it's a but worse but still about 15.8 km/ litre. 2 Link to post Share on other sites More sharing options...

Most of the time is 2 adults (and sometimes +1 baby). Super duper light foot cause cannot rev and cannot pia in first month so quite sad the FC cannot match anywhere near advertised figures (17.2km/l) =D Yeah expected it to be lower, but SO MUCH LOWER?! Perhaps it is because the air con fan speed need to on at least speed 2 to make the car cold enuf... Ur car is <1100kg which is consider quite light n the rim is small. 12.8km/l is quite unacceptable to me, specially this is a tiagong good FC car Link to post Share on other sites More sharing options...

OTOH side aircons are really strong so I had to off the one on the passenger side cos it is causing condensation on the side window and thermostat is set at 24 degrees.

Sounds decent for a B58 engine. Not comparing as the weight is very different but I'm getting about 6.2km/litre on a G06 based on 80% city / 20% freeway. I thought it is already an improvement for the B58 as I used to get similar consumption on the F06 (N55) which is ~10% lighter in weight. Link to post Share on other sites More sharing options...

Rickster 5th Gear December 2, 2020 Share December 2, 2020 (edited) My previous BMW 116D. It's a diesel car. Who says BMW can't be economical? 😜 The below pictures shows the average fuel consumption over a distance of 1693KM. I've achieved 25KM/L if i just drive in the middle of the night with no traffic.

Your X6 (unless is X6M) actually has a better drag co-efficient at 0.32 than my little car which is 0.34! 1 Link to post Share on other sites More sharing options...
