Hooray, another mid-sized, bland SUV.I'll keep £5k and get myself a top-spec Sportage please.
Just done the rounds to replace my Freelander 2, looked at them all, no competition, ordered another Freelander, job done.
Constant waste of energy with "daytime running lights", LED or not , is NOT a good thing!
....however, let's say there are 20 x 1 watt LEDs on all the time as a guess.-20 Watts continuous as an estimate.-The engine produces 145000 watts peak, let's say it averages half of that under normal use. 72500 watts.-The lights consume a nominal 0.000275 fraction of the engines power.-If you roughly assumed that the fuel consumption and co2 emissions are linearly related to power production over a small change like this you would be talking about a change of 0.0275% for the worse.-Co2 would go up by 0.05g co2/km-MPG would go up by 0.011 MPG
Or, to put it another way, to create a change of 1mpg would require about 1820 LEDs @ 1 watt on continuously?
There are obviously larger offenders.
...Such as the fact that it looks about as aerodynamic as a bus.
To simonrh1. Is your second name Einstein? Wish I was that clever.
Yyyyes, he also has a sssstutter! I'm surprised he hasn't given us the aero statistics to back up his impression!

Would you want a aircraft-style black box data recorder fitted to your car to help determine fault in insurance claims?
