2014 Volkswagen Passat TSI: Fuel Economy Update for August
September 4, 2014
In August, we drove our long-term 2014 Volkswagen Passat TSI about 1,700 miles and averaged 28.2 mpg. It wasn't as busy as July for the silver sedan, when we added 3,200 miles to the odometer, but we still drove the Passat up to central California for a weekend and on a day trip out the farther reaches of Los Angeles County.
Road trips are the Passat's specialty and we recorded two 30-mpg tanks this month on trips of 421 and 470 miles. The additional mileage in August also bumped up the Passat's average lifetime efficiency to 27.2 mpg, edging closer to the EPA's rating of 28 combined.
But as Senior Editor John O'Dell noted last month, the Passat still wildly exaggerates its own efficiency. This month, it inflated its indicated mpg as much as 6 mpg, claiming 36.4 mpg on the long 470-mile trip. Its actual mpg was 30.0. And as in the photo above, even with 56 miles already on a new tank, the Passat wants us to believe it can range another 500 miles. At 494 miles, we’ve been close, to this estimate anyway.
