HOW?! Are you consistently getting over 50MPG or is that just a one off thing? From what I've seen online most people get around 24MPG in those. I have to really push my Jetta to get 40MPG when it's supposed to get 42 on highway.

It's not a one-off. My A220, even with the 4MATIC, it’s quite efficient. It's got a really well-tuned 2.0L turbo engine, and a lot of it comes down to the 7-speed dual-clutch transmission (7G-DCT) keeping the RPMs low at highway speeds. I also utilize the ECO drive mode quite a bit. What kind of Jetta do you have? Sometimes even small differences in engine tuning or transmission can make a big difference.

Welp, the EPA rates the A220 4MATIC @ 24 MPG city / 34 hwy (combined average 28 MPG), so it may be that yer little German fuel computer is lying to you :\

I mean hypermilers are able to outduel the already stringent EPA testers, but not by double

It may even be that you had just reset the mileage computer after filling up, and the true consumption has not yet set in

@W0LFB3AT5:

Even with my last car, a 1.0L 3 cylinder turbo Focus with the 6spd manual (with two OD top gears, and 50 HP less than yer Benz), I was only able to wring out about 42-43MPG combined driving gently

... and I rarely drive gently; if I did in my current truck, the adaptive learning transmission would drive like a sack of foreskins
(I rarely get better than 20MPG now, but it is a V6 4x4)

2011 Turbo Diesel with 6 speed auto DSG. Wish it had the 7 speed the later models did, since it's in 6th gear by 40MPH. My route to work is on a 40MPH road, but being city driving the efficiency isn't great. 2400RPM on highways :/
