2012 C Coupe
According to the article, there will be 3 engine sizes: 1.8L Turbo, 3.5L and the 6.2L. The fuel consumption numbers of the 1.8L is 6.5-7.0 L/100KM and 6.7-7.0 L/100KM for the 3.5L.
Do these numbers seem right? How can the gas mileage be similar if the engine is about 50% difference in size?
My CLK320 gives reasonable gas mileage on the engine size. Since this is my daily commute and with the ever increasing gas prices, I may consider a 4-cylinder for my next car.
Based on the official consumption numbers of the C-Coupe (Below), the new 6-cyl and the new 4-cyl (Turbo) are almost the same. Maybe this is possible now because of some technology breakthroughs.
I would think the 3.5L engine would get similar gas mileage as my CLK320.
If it is true that I can get 6.7-7.0 L for the 3.5L, I would definitely get the 6-cyl.
6.75 L/100KM = 34.84 MPG
7.0 L/100KM = 33.60 MPG
With my V6, the best highway mileage I can get is 8.0L/100KM (29.40 MPG). This is all highway, I reset the computer when I get to the highway.
So, it's hard to believe those numbers, and they are supposed to be average highway/city mileage.
This is why I posted this thread for comments.



that's a bit unbelievable based on my usage in 2003 CLK320. Granted I have very short commute of 4 miles each way to the train station and then beck. With sometime longer trips (5-10 miles) on weekends. I do hit the gas on occasion but most of the trip is on longer stretches doing 50mph and then 35mph. I average about 19/20mpg according to the on board computer.

But I guess if you do mostly highway runs then its definitely doable. I only put on about 4k miles a year so 18mpg or 25pmg makes no deference to me



I googled http://en.wikipedia.org/wiki/Gasoline_direct_injection. Apparently, this Direct-Injection technology is not that new.
