Totally stock, my car is getting 14.1mpg in 7 months of driving, that is amazing the gas mileage you are getting, even with your aftermarket upgrades.

The numbers are over multiple tanks of gas and seem to be consistent tank to tank. Steptronic mileage may be better than manual because steptronic keeps RPMs lower than most manual drivers do. For instance, in the wife's Cayman (when she lets me drive it), I tend to keep around town revs at 2200 or so just to have reasonable reponse. The 335 is usually at 1500 with bags of torque and it will downshift quickly if you do need more. Cayman mileage with me driving is 18 to 20 around town and 25 on the road. I also note that the steptronic in sport mode gets much worse mileage, more like the manual Cayman numbers. That seems to be right because it's shifting at about the same revs.

Frankly, I thought the numbers make a lot of sense. The 335 engine is small (only 3 litres), has 10.5 compression, steptronic selects relatively low revs in normal driving, steptronic has low losses for an automatic since it is locked up 99% of the time, engine is direct injection, has variable valve timing and the car is moderate weight with good aerodynamics. Even in harder driving, the engine makes great power at efficient low revs. Revving around in the Cayman is great fun but at this altitude (5200') it makes less power at 5k than the Proceede 335 at 2500 revs.

One note about the highway mileage is that the temperatures were ideal: there was little or no wind, if it were warmer the air conditioning would have used more gas; cooler and the tires and lubricants would have offered more drag. On the other hand less fun with the go pedal would have helped.

If you haven't guessed, I think the 335 is a perfect car or at least as close as can be bought at this time. I was off to put a deposit on an LS600H hybrid Lexus when I stopped by the local Bimmer vendor. After 500 feet in a 335, I was sold, two miles and I was totally committed. You owners at sea level can't appreciate how much POWER this car still has at one mile high. The Cayman S is lots of fun but it's so slow.

18-20 mpg with some aggressive driving. 50% highway/ 50% city. It drops VERY fast when punching it around town.

something i was thinking about, is the on board gauge still accurate? i dont do the whole remember how many gallons you put in thing, but i noticed everytime i look down im out of gas nowadays

and since the ECU shouldn't know that theres more fuel being injected ...

but it seems like it is

No PROcede yet, so I am off topic, but for comparison purposes I get around 30 mpg on steady, slow (80 mph) highway -- less than the 33 mpg I got with my 323 E46. Around 'town' (not a city, no stop and go) I get about 24mpg. I love to accelerate hard, but I also glide, and immediately get off the gas when I see a red light ahead.

Wow! Most of 335s are getting outstanding gas mileage!

With my Evo I get 21-23 mpg @ highway 80-85 mph, 15-17 mpg around town, 7-8 mpg @ 125-175mph on the autobahn and 4 mpg at the track

...and its a small 2 liter 4 cyl

15mpg average on 3500 miles. My e39 M5 was always less than 10mpg. I'm saving.
