TrueDelta Reviews the Real Gas Mileage of the Tesla Model S

Tesla Model S Real Gas Mileage: Pros
Year	Comment
2013	If the Tesla Model had a conventional gas-powered engine, few people would care about it. Plenty of established companies offer stylish, powerful, and luxurious sedans. Why place a $70,000+ bet on a new car from a new company? The reason just about everyone (and their mom) has heard of this upstart car company and its first completely in-house product is that the Model S, with its battery-powered electric motor, was engineered to render conventional cars passe. For anyone who must have the latest tech, it is the car to get. Two battery sizes are offered, 60 kWh and 85 kWh, the latter an additional $10,000. (A 40-kWh battery--actually a 60-kWh pack electronically limited to two-thirds of its capacity--was initially offered, but few early adopters opted for it and it has been discontinued.) The EPA rates the former for the equivalent of 94 mpg city, 97 mpg highway, the latter for 88/90. For reference, the much smaller, far less powerful Nissan LEAF is rated 129/102, considerably better in city (actually suburban) driving but not much more efficient on the highway. Among gas-powered competitors, the Audi A7 is rated 18/28 and the more powerful S7 is rated 17/27. Tesla's big advantage over other electric cars involves their shared primary limitation, range. In EPA testing, the LEAF's range was 75 miles, and other electrics in its price and size range manage about the same. In the same test, the two Model S packs achieved 208 and 265 miles, respectively. (Note: Range is significantly shorter for all electric cars in cold weather or when running the A/C.) Consider cost per mile, and the Tesla's fuel economy seems even better. At the national daytime average of 12 cents per kWh, the cost per mile is about four cents. (Charge at night, when rates are often discounted, and it's even less.) In comparison, an Audi A7 or S7 has a fuel cost of nearly twenty cents per mile. The average driver can save over $2,000 a year by driving a Model S. The major downside of the Tesla's electric powertrain (beyond purchase price) is the time required to charge its battery pack. With twin onboard chargers ($1,500) and a high-powered wall chargers ($1,200 plus installation) each 62 miles of range requires an hour. Easily practical for typical daily driving, but not for long-distance travel. For long-distance travel, Tesla is building a network of "Superchargers" and battery swapping stations. The Superchargers can provide half a full charge in 20 minutes. Free use of these is a $2,000 option with the regular pack and included in the price of the larger one. You'll be able to have the battery swapped in as little as 90 seconds. But the swap will cost $60 to $80 and you'll have to stop on the return trip to have the original pack re-installed or pay an additional charge. These stations will make long-distance travel feasible, but it will still be less convenient and/or more expensive than in a gas-powered car. see full Tesla Model S review

Mercedes-Benz R-Class Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2010	4dr SUV turbocharged 210hp 3.0L V6 Diesel 7-speed shiftable automatic AWD	Excellent. We average 27 on the highway travelling at 70+mph see full Mercedes-Benz R-Class review
2009	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	Pleasantly surprised by first tankful. 16.2 mpg in the city. Mostly used "comfort" setting which starts out in 2nd gear and shifts early. With this nonaggressive profile, city driving economy is improved. Premium gives better gas mileage than regular (about 5% on comparable tankfuls). On Comfort setting, no difference in performance is noted. see full Mercedes-Benz R-Class review
2008	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	It easily gets to 20 mpg on highway. About 18 on mixed driving see full Mercedes-Benz R-Class review
2007	4dr SUV turbocharged 215hp 3.0L V6 Diesel 7-speed shiftable automatic AWD	Excellent fuel economy with the diesel, especially when driven gently. Also amazing power at the same time see full Mercedes-Benz R-Class review
2007	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	15mpg city....25 mpg highway....combined is around 17-18 mpg. Not bad considering how heavy this car is. Of course i am very light to the pedal trying to keep my mpg high. Gas is too expensive nowadays so if i don't need to be fast, i am keeping it steady. see full Mercedes-Benz R-Class review
2006	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	Much better than expected for a very large and long vehicle. Close to 25MPG on longer trips. see full Mercedes-Benz R-Class review

2007	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	15 mpg average. Not good see full Mercedes-Benz R-Class review
2007	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	Pretty poor for a 3.5L. see full Mercedes-Benz R-Class review
2007	4dr SUV 302-horsepower 5.0L V8 7-speed shiftable automatic AWD	F-E is poor because of the weight to power ratio. The vehicle is heavy. With the available power, it is easy to drive faster and to maneuver through slower traffic. Frequent acceleration results in lower gas mileage. see full Mercedes-Benz R-Class review
2006	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	I would probably choose a diesel next time for efficiency reasons - but the additional premium fuel required in the V6 is negligible once the car is paid for....soon now. Very lively engine too. I foresee a hybrid R class type vehicle after 2011... see full Mercedes-Benz R-Class review
2006	4dr SUV 302-horsepower 5.0L V8 7-speed shiftable automatic AWD	only 17 mpg highway see full Mercedes-Benz R-Class review
