So I've seen several threads about excellent highway economy from the diesel Cruze's but I'm wondering what most drivers who do a majority of city driving are seeing in mileage? The '27' number is a bit concerning when other TDI models don't dip that much in the city so I'm wondering if its overly conservative (didnt they change the calculations anyway?) or if the car's mileage dips that badly in heavy traffic?
My commute to work is 18 miles- half city and half interstate going 70mph. This would be 80% of the car's mileage and I am wondering if the diesel Cruze is my best option. Coming from my Jetta, I'm already very partial to diesels but want to be objective about at least averaging mid to high 30s out of my work commute which is half stop light to stop light and half lead foot past slower drivers once I'm on the interstate.
