Specs, explained
It uses the 3.5L 6-cylinder and front-wheel drive. It runs on regular gas. With front-wheel drive, the weight of the engine sits over the driven wheels, which helps in winter.
Rated at 12.4 L/100 km combined, it needs around 37 litres for a 300 km round trip. At our price setting, driving 100 km costs about $19.22, and a 300 km weekend about $57.66. At US fuel prices, the EPA estimates US$3,550 a year for 15,000 miles.
Inside and out
As a full-size SUV, it sits higher than a sedan, which makes getting in and loading easier.
A good match for
It suits winter trips and weekends with more gear than people. It suits a stretch between cars, by the week or the month.
Try before you buy
Rent the Flex for a week, or up to 365 days, before you commit to buying one. Rent the Flex first, and buy only if it fits your life. Try the Flex on your commute, then decide.
What it costs to run
Ask what a set of tires costs for this trim; sizes and prices vary. The EPA estimates US$3,550 a year in fuel for 15,000 miles at US prices. At our price setting, 100 km costs about $19.22 in fuel.
Year and trim
If two trims share a powertrain, the difference is equipment, which you can check in person. Within the 2018 lineup, trims share powertrains or differ in equipment; the trim pages show which. Look at a few listings of the same year and trim to get a feel for fair prices.
