Diesel here in California is
Diesel here in California is $2.45 while gasoline is in the low $3.
I get that 45mpg ave per tank, so not even taking the price into account it's still more efficient.
That's also driving my beetle 80-85mph on the freeway.
The VW claimed mpg is lower than what u really get in real life. And also the mpg of diesel doesn't fluctuate as much with my driving habit.
I've had a 2013 corolla where I struggled to get 30mpg ave on a tank when I drive it 80-85mph on the freeway. I'll have to really baby the gas pedal to get it up to 33mpg.
I don't know about the new 2016 corolla maybe they have direct injection w/c would increase the mpg of it but I don't think it'll be anywhere close to a diesel jetta or beetle efficient mpg.
