I have a 2018 Redline with around 28,000 kms (~17,400 miles) although I have had the common Transmission shutter last year and the shifter assembly this year, it is still one of the best vehicles I have owned in the past 46 years that I have been driving (legally :wink .
It is very comfortable, economical, has tons of safety features and get compliments from strangers of all ages on a regular basis.
I have attached a picture of my recorded fuel economy from my last big trip.
Here are the numbers for my friends who live south of our border:
The trip was 1,142 kms (710 miles) one way
I used cruise control 90% of the time. It was set for 115 km/hr (71.5 mph)
The picture shows the economy for the last 50 miles
Avg: 7.8 L/100km ( 30.5 miles/gallon (US))
Best: 7.1 L/100km (33.1 miles/gallon (US))
That is just awesome for a big vehicle with a big V6.
I just love my Traverse
