It is rated at 46MPG HWY.
Starting price is $ 25 700.
Which is just 4MPG than the $ 21 000 Eco model.
Although the Diesel model does have more standard equipment, like leather and automatic.
But, at least in California, Diesel is usually much more expensive than regular gas.
GM is also comparing it, of course, to the Jetta Diesel. Which is rated at 42MPG HWY.
From personal experience, the VW diesel has always returned over 50MPG on the freeway.
So 46MPG for the Cruze might be a conservative number.
Looks like Diesel is really making a come back in the US.
As Mazda is also planning diesel versions of the Mazda6 and CX-5 in the US soon.
