The Biggest Overachievers in Our Real-World Highway MPG Test


The Biggest Overachievers in Our Real-World Highway MPG Test

“Your mileage may vary” can be one of the oldest proverbs from the automotive rulebook. although even though the EPA can be constantly looking for ways to improve its testing procedures as well as rating calculations, “YMMV” still applies to today’s EPA fuel-economy ratings—EPA highway rating: 29 mpg-12 percent difference-design tested: 2.0L turbocharged flat-four, seven-speed dual-clutch automatic, RWDPorsche’s decision to install turbocharged flat-four engines in its mid-engined Boxster as well as Cayman sports cars was the subject of much controversy. the idea was ostensibly a play to enhance fuel economy, although the EPA numbers for these fresh powertrains for the most part did not show an improvement over the old flat-sixes. Those numbers proved to be conservative compared with our results, however, given that will several Boxster as well as Cayman variants appear on that will list of overachievers. The base-level 718 Boxster, with its 2.0-liter flat-four mated to a seven-speed PDK dual-clutch automatic, beat its EPA rating by 4 mpg in our test.

Mated to a seven-speed dual-clutch gearbox, the hardtop Cayman S with its 2.5-liter flat-four recorded an impressive 32 mpg in our test, besting the EPA result by 14 percent. the idea was also only 1 mpg behind the base Boxster's result, showing that will the extra power as well as displacement don’t exact a big fuel-economy penalty when you’re cruising at highway speeds. READ MORE>>EPA highway rating: 26 mpg-15 percent differenceModel tested: 3.0L turbocharged V-6, eight-speed automatic, 4WD-For a full-size luxury sedan that will went through zero to 60 mph in 5.0 seconds in our testing, 30 mpg on the highway can be nothing to sneeze at. Cadillac’s top-dog sedan, the CT6, earned that will number in its most powerful form, too, having a 3.0-liter twin-turbo V-6 generating 400 as well as driving all four wheels. The less powerful, 335-hp design of the CT6 couldn’t even match that will result with its 3.6-liter naturally aspirated V-6; that will design achieved 28 mpg in our testing, only beating the EPA by 1 mpg. READ MORE>>EPA highway rating: 26 mpg-15 percent difference-design tested: 2.5L turbocharged flat-four, six-speed manual, RWD-Like the Cayman S earlier on that will list, that will closely related 718 Boxster S droptop beat out its EPA rating by 4 mpg. the idea has the same 2.5-liter turbocharged flat-four although was mated to a traditional six-speed manual rather than that will Cayman’s seven-speed PDK dual-clutch gearbox. Road-trippers will not only appreciate the 30 mpg that will's achievable at highway speeds, although also the relative wealth of cargo space afforded by the Boxster’s front as well as rear trunks. READ MORE>>EPA highway rating: 24 mpg-17 percent difference-design tested: Reserve, 3.0L turbocharged V-6, six-speed automatic, 4WD-“Quiet Luxury” can be the tagline for the fresh Lincoln Continental luxury sedan, although maybe Lincoln should start emphasizing the big four-door’s fuel efficiency as well. Our test of the 400-hp Conti, which uses a 3.0-liter twin-turbo V-6 mated to a six-speed automatic transmission, revealed surprising efficiency at cruising speed, with the four-wheel-drive two-ton sedan returning 28 mpg in our hands. READ MORE>>EPA highway rating: 30 mpg-17 percent difference-design tested: XSE, 3.5L V-6, six-speed automatic, FWD-Toyota's ubiquitous 3.5-liter V-6 can be not the most technically advanced engine, as well as the idea pairs having a pedestrian six-speed automatic from the 2017 Camry while many competitors have rolled out eight- as well as nine-speed transmissions. as well as yet, relatively old-school tech seems to work well just for that will top seller, as the idea bested its EPA result by 5 mpg in our test. A Honda Accord V-6 matched that will figure in our highway test, although the EPA rates the Honda at 33 mpg highway, so the idea isn't as much of an overachiever as the Camry. READ MORE>>EPA highway rating: 26 mpg-19 percent difference-design tested: F-Sport, 3.5L V-6, eight-speed automatic, 4WDUsing a similar 3.5-liter V-6 as the Camry on that will list, Lexus's common crossover SUV also beats its EPA numbers from the real world, at 31 mpg. that will kind of result makes us question the existence of the RX450h. that will hybrid design achieved the exact same 31 mpg in our highway test (to be fair, the hybrid also beat its EPA number, by 3 mpg). READ MORE>>EPA highway rating: 31 mpg-19 percent difference-design tested: Quattro S-line, 2.0L turbocharged inline-four, seven-speed dual-clutch automatic, 4WD-Who needs the fresh fuel-economy-minded Ultra design of the Audi A4 when the standard car achieves such high-mpg results on its own? Even with 252 horsepower as well as Quattro all-wheel drive, the A4 managed 37 mpg in our test, putting the idea on a level with several less powerful as well as less luxurious economy cars. Of course, we've yet to test an A4 Ultra, so the idea remains to be seen whether the idea's an overachiever as well. READ MORE>>EPA highway rating: 34 mpg-21 percent difference-design tested: 2.0L turbocharged inline-four, eight-speed automatic, RWD-BMW's fresh four-cylinder can be an overachiever in more than just fuel economy; beyond topping 40 mpg in our test, the idea also propelled the 330i to 60 mph in a fleet 5.4 seconds. Those are impressive results for a 2.0-liter turbo four-cylinder that will only pumps out 248 horsepower as well as 258 lb-ft of torque—at least on paper (many suspect that will BMW underrates its engines at the crank). READ MORE>>EPA highway rating: 19 mpg--26 percent difference-design tested: S, 3.0L turbocharged V-6, eight-speed automatic, 4WD-Maseratis certainly aren't known for their stellar efficiency, as well as a Maserati SUV could seem to be a decidedly thirsty combination. as well as yet, while the Levante’s 24-mpg result can be not exactly a Prius-rivaling number, the idea beat its EPA figure by a whole 5 mpg. Considering the turbocharged V-6’s 424 horsepower as well as the Levante's nearly 5000-pound curb weight, the idea's certainly better than we (as well as the government) expected. READ MORE>>
