By 2021, phased in from 2020, the fleet average to be achieved by all new cars is 95 grams of CO2 per kilometre. This means a fuel consumption of around 4.1 l/100 km of petrol or 3.6 l/100 km of diesel.

To encourage eco-innovation, manufacturers can be granted emission credits equivalent to a maximum emissions saving of 7 g/km per year for their fleet if they equip vehicles with innovative technologies, based on independently verified data. [0]

So this move is more of a combination of short-term gains of less-restrictive emissions, and a long-term move to electric.

This means nothing due to the idiotic way fuel consumption is calculated for PHEV. A 2+ ton hybrid SUV like the Volvo XC90 is rated as 2,1 liters/100 Km while it easily burns 10+ liters when the battery is empty or the electric engine can't keep up (i.e. on the highway).

Just as a reference, that's 57mpg for petrol and 65mpg for diesel, and that's average, not peak, for all cars. A good diesel estate might average 50mpg if driven carefully, but in towns a lot less. So there's a long way to go. Companies will need to build/sell/operate a lot of tiny cars, or definitely have significant electric and hybrid parts of the fleet.

Going to fuelly.com, newer Golf TDIs seem to average out at 40 mpg, with the tails trailing out by +/- 5mpg:

The older 1.9L engines are slightly better.

Ah yes, i forgot Americans gallons are 4/5 size. Adjust data accordingly, so i did mean 40mpg US! (Most modern diesel estates(station wagons) do up to and sometimes over that, such as mazda 6, Ford Mondeo)

Whew, that's going to be interesting. Toyota can hit that with the Prius Eco... if that was the only car in their fleet.

Well, they can easily achieve this with plug-in hybrids (and obviously battery-electric cars) just by tightening up the average distance a car is driven per day. My PHEV is averaging a solid 300+ MPG, because I fill the tank every 2000 miles, because I only drive it 20 miles on most days. Tolls and sensible development patterns can lead to shorter trips.

I love that page, I haven't seen a comprehensive policy document that was so readable.
