Based on the trip computer, my drive, which involved stop - and - go freeway driving and some surface streets, I was getting about 34 mpg.
Keep an
eye on the trip computer during any test drive for a more realistic economy figure, and ask the dealer to show you how to access this information if you're unsure.
While the automaker says the M2 averages 7.9 liters per 100 km (EU) or 21 mpg combined (US) with the M DCT gearbox, the lowest figure we
saw on the trip computer was 13.5 l / 100 km (equivalent to 17.4 mpg US).
EPA mileage numbers, at 29 mpg city and 38 mpg highway, should lead to an averages in the mid-30s, although in my mixed city and freeway driving I never broke 30
mpg on the trip computer.
The exhaust tone deepens further, the steering gets heavier, and with the engine's vital temperatures showing warm on the bespoke AMG
menu on the trip computer, the first sweeping bend leading to a motorway slip road offered a chance to really get the hammer down.
During our time with both models, we didn't get much above
30mpg on the trip computer, which isn't far off the claimed figures, but around 15mpg down on the diesels.
In real world conditions, the reading
on the trip computer of the test car showed an average of 48.6 MPG at the end of my time with it, though the Lexus can regularly reach figures of 50 MPG easily with some sensible driving.
Standard equipment includes front, side and dual knee airbags; tyre pressuring monitoring; a reversing camera displayed through an 8.0 - inch touch screen that also runs the SYNC2 infotainment system and voice control; nine - speaker audio; dual zone climate control; sat - nav; heated, cooled and powered leather front seats; a rather cheap looking stop - start button and a whole heap of performance and technical info which you can scroll
through on the trip computer.
During a long freeway trip, I found the engine remained on most of the time, resulting in fuel economy
on the trip computer hovering around 42 mpg, even as I tried to be gentle with the throttle.
Fuel consumption
indicated on the trip computer hit a high of 9.3 L / 100 km with plenty of fast lapping of the private road, but settled to a very respectable 5.9 L / 100 km on an easy highway cruise.
Like other Ford models, the Mustang has a handful of interior accent colors, but unlike economy cars such as the Fiesta, which have a toggle on the dash, you need to delve deep into the
menus on the trip computer to change the interior colors.
While diesel versions pack more grunt and will deliver far more impressive figures than the 18mpg
shown on the trip computer, our 201bhp 2.0 - litre TSI petrol model is quiet and smooth, and the massive, comfortable driver's seat is positioned behind a very car - like dashboard.
My final fuel consumption figure,
based on the trip computer, was 7.2 L / 100 km which is entirely reasonable for a hulking 2310 kg tub.
It's all but impossible to achieve that figure on normal roads in normal driving conditions, but you will see numbers close to
that on the trip computer if you do a lot of highway miles.
Of course, all of this accelerator work and hard cornering isn't in line with the hybrid's main virtue, fuel economy, but we still rolled into the garage with an average mpg of 31.7
on the trip computer.
Don't expect to see

Don't expect to see
this on the trip computer if you explore that rip - roaring engine, though, while the 258g / km CO2 emissions put it in the highest tax bracket.
First, there are two clocks on the Grand Cherokee, one on the stereo and one
on the trip computer's message center.
