I think the Mercedes GLC gets pretty good gas mileage. All these guys are getting around 30MPG....
When I got home that night it was 9.4L/100 or 24.7 mpg!!! So this car is very sensitive to driving conditions. It much prefers highway driving....
Most of my longer trips with the majority of the driving being highway I've gotten 27-28 MPG, however I did get 30.9 MPG on a recent trip from Los Angeles to Las Vegas.
2018 Volvo XC60 T6 Denim Blue
2012 Fiat 500 Pop
1965 Ford Mustang Coupe 289 A Code 4 speed
1970 VW Beetle
Always relative to driving conditions which are rarely stated.
Under similar conditions over first 500 km I'm seeing (US mpg)
XC90(1)T5 > XC60 (2)T5
16mpg > 20 mpg (short trips / stop start)
22mpg> 29mpg (commuting 50km mixed urban / rural)
26mpg > 31mpg (highway)
Recent Highway trip:
leg @65 mph: 25.7 mpg
leg[email protected] mph: 23.5 mpg
City still tough...about 15+ mpg
If I get out on roads that can catch some green lights it's better. The 4 way stops are deadly. And short trips, since the first km seems especially inefficient. I also get the impression that if damp/wet out, the efficiency drops. Is that a thing?
I'm not convinced the auto-on/off is helpful.
I've got a 2019 XC60 T6, and I'm just shy of 10,000 miles.
Getting 22.6 mpg, almost exclusively driving in Comfort mode. Pretty easy for me to get 25-26 on a drive if conditions are good, but I do a little bit of sitting in traffic that costs me (and accelerating...). Leaving start/stop on made a noticeable difference when I tested it early on, so I've left it on all the time now.
