When will we see the first 100mpg Claimed Production Car
Discussion
175mpg coming in spring 2012: http://www.vauxhall-ampera.co.uk/index.php/eng/amp...
"What kind of petrol mileage will the Vauxhall Ampera get?
That’s a bit of a trick question. Because for the first 40 miles, no petrol will be burned*. But when the generator starts, fuel consumption is estimated at:
Fuel Consumption / CO2 emissions according to UN ECE R10*
(weighted, combined):
175 mpg* (preliminary information)
40g CO2/km* (preliminary information)"

Watching TV last night and advert for the New Kia Rio claims 88mpg, so got me wondering how far off are we from a (claimed) 100mpg car and who will be the first Manufacturer to make the claim?
I'm going to go with VW. This new little Up thing could have had the potential. djt100 said:

Oddly, I was thinking that when I heard the advert last night as well.... My mind went with VW - some bluemotion thing or other...Mr Gear said:

I've always thought this was the best idea, an engine charging up a battery pack, but why are they using a petrol engine, surely a diesel with it's greater torque would be better, running at lower RPM would be more economical and could be geared to spin at the speeds needed to charge the battery pack?"What kind of petrol mileage will the Vauxhall Ampera get?

I was thinking the same thing. Weight of petrol vs diesel was all I could come up with.budgie smuggler said:

They wait until you've already bought the lesser one first djt100 said:

The car is a GM world product, and therefore needed to sell in the USA and Japan where they don't "do" diesel in passenger cars. Also, diesel produces nasty pollutants other than CO2 that we in the EU are lucky we are not penalized for.djt100 said:

Diesel has cost and complexity issues when combined with an already expensive hybrid/electric powertrain. It's also a bit tricky with NVH as the engine runs at more continuous speeds than with a 'normal' powertrain, and a diesel generates more vibrationPlus, diesel's major benefit is part load efficiency with a normal car, with a range extender it'll be run at its most efficient operating point for a given power demand, narrowing the efficiency benefit between Petrol and Diesel
There are few people who care more about the fuel economy of other people's cars than a true petrol-head. 
Lets be honest, 95% of cars that sell in the UK today, are dull as a very dull thing. They aren't going to lose any character by becoming more economical because they have no character to lose.

Bingo Which is why i can't understand why folk are scared of electric cars.
Its not like a Vauxhall astra could be any duller
