Attempt to get 75 mpg with a 451 model smart car with a gasoline engine
As I write this, I am in Edson Alberta, preparing to head out Friday for familiar hypermiling territory in Saskatchewan.
I’ve brought my 2008 gasoline smart, also known as the 451 model. It’s rated for 4.9 L/100 km on the highway, but already this trip, I have achieved 3.9 L/100 km between Prince George, BC and McBride. I’ve not made any serious attempt to beat 4.0 with this car until now. I am looking to see what it is capable of, and am hoping to beat 75 mpg (imperial).
The car is stock, except I actually am running LARGER wheels and tires, 175 mm on the front and 105 mm on the rear, versus the 155/175 set-up as delivered. This should be costing me about 0.2 L/100km. Also note - I have a full compliment of camping gear in the car.
Friday, I’ll be passing through Edmonton and will be making a stop in Mont Nebo, SK, before finishing the day in Birch Hills, SK. Saturday will be the real test, as I head off for Wadena and possibly Yorkton, in search of the best mileage I think I will get. I took my first diesel smart here in 2005 and 2006, and achieved my best mileage record to date, surpassing 100 mpg US on the 2006 run.
Interestingly, I did not have the benefit of real-time feedback that the Scangauge II provides in either od those years. Although the gas smart won’t touch the numbers the diesel can reach, I’m fairly confident I can get a pretty respectable number. I’ve got a handful of Scangauges with me on this trip if anyone is interested in purchasing one. You can reach me at ’six oh four, six three six, twenty-one eighty’. I’ll be heading back to BC westbound, possibly through Calgary on Sunday.
More updates and photos will be posted as they are available.
