#5 of 13 Long trip mpg by extech2 Sep 23, 2007 (2:05 pm)
I calculated my average mpg on a 1400 mile trip as 27.4 and the onboard comp. gave me 27.6 which is very close. This includes dirt roads, city streets, country roads and highway miles up to the top speed of 133. I will write a longer report on the general GTI forum. Don't get this car for superior gas mileage because you will be disappointed. As a true sports car the GTI works great.
#6 of 13 same problem by spawn6578 Nov 23, 2007 (6:56 pm)
I am having the same problem. My milage inside city is ~14 mpg and it started after 4500 miles. I went to my local dealer and they checked the engine but they told me that they couldn't find anything and engine is fine.   petervm is your problem solved? if so, how and what was the problem?
#7 of 13 Mileage by upstatedoc May 05, 2008 (12:41 pm)
Just about 1.5k miles on the GTI now, mixed driving I'm getting around 24 mpg. Highway I can't seem to break the 28 mpg barrier, the best was 28.4 mpg purely highway at around 75mph.   Yesterday I decided to "stretch" the GTI's legs a little on the highway to see what the mileage would be at high mph. At between 85-110 mph (don't try this at home) for extended periods I was still able to get 27mpg! BTW, the car is rock solid at any speed, even more so than the '05 TL I had a while back. Smooth as silk, even 110 mph there was still plenty of tachometer to go. Awesome.

Replying to: upstatedoc (May 05, 2008 12:41 pm) I get about 21 MPG in city driving, in heavy traffic. This with driving gently with an occasional quick pass. The comp. will show about 0.5 more, as 21.5 averaged over several tanks. Going home Friday night in very heavy traffic I'd get 20. Going back to work Saturday morning, no traffic, my comp shows 25 MPG for a 13 mile drive. On the freeway I can get about 27 MPG. Once I had it redlined and the car topped out at exactly 133 mph, verified by the Garmin GPS. When I glanced at the current MPG readout I've seen 6.7 MPG. The car handles that speed really well, no drama to it. And I agree, don't try this at home. Mine is an 07 GTI with the DSG transmission. Replies to this message: roscoe108 (May 22, 2008 8:45 am)

Replying to: extech2 (May 17, 2008 12:49 pm) I have an '07 GTI with the 6-speed manual, and the odometer reading 7,500 miles. Thirteen mpg is horrendous, I totally agree.   Before modifications, I was seeing 21 mpg city and 31 mpg highway. After getting the APR engine remap and a Neuspeed cold air intake, my mileage has improved. Now I'm seeing about 22 - 23 mpg in the city (mix of normal driving, stop-and-go, and leadfoot) and 36 mpg highway. The highway figure surprised me quite a bit, but I drive reasonably on freeways (about 70 mph) and use the cruise control whenever possible. And yes, I came to that figure based on actual fuel consumed, rather than the computer readout.   The APR chip boosted torque by quite a bit (up to 303 lb-ft over the stock 207), which allows me to get up to speed using lower rpm's, which helps reduce gas consumption. Meanwhile the CAI helps with more efficient breathing and cooler air for the turbo (for greater combustion). The two mods together are a well-paired combination of technologies.   So, 260+ horsepower with a combined 28 mpg. Works for me :>)

Replying to: upstatedoc (May 05, 2008 12:41 pm) "Smooth as silk, even 110 mph there was still plenty of tachometer to go. "   maximum speed in not limited by engine RPM. It is generally limited by the final rear end ratio or by engine computer software.   I remember driving on a German autobahn in a Volvo with overdrive. As an experiment, we drove with and without overdrive. The maximum speed was the same, just lower RPMs with overdrive.
#12 of 13 Long trip mileage, 07 GTi with DSG by extech2 Oct 24, 2009 (2:48 pm)
We just spent 10 days in Arizona, in the month of October, using the air cond. 70% of the time, driving 1,700 miles in our 07 2- door GTI, equipped with the DSG automatic transmission. The car was fully loaded with luggage everywhere, in the trunk, on the back seats, and the two of us. The average mpg was shown as 28.7 in the computer. My experience is that the actual mileage is about 4% less, so we got about 27.5 mpg. This included mostly freeway travel at speeds around 75 or a bit higher. We hit 100 maybe three times, for a short period only. The interesting part is that when driving on secondary roads, which in Arizona are superbly maintained, at speeds between 45-60 miles, our computer usually displayed 32-36 mpg unless climbing steep hills. Most of the time we were at 4,000 feet or higher altitude, in the Sedona or Flagstaff area in high mountains. The car never had a single problem in 2.5 years and it always starts the 1st time.

Replying to: extech2 (Oct 24, 2009 2:48 pm) Excellent mileage from such a potent little power plant! I was approaching 30 mpg on my '08 6 MT during my highway commute.
