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

TrueDelta Reviews the Real Gas Mileage of the BMW X3

BMW X3 Real Gas Mileage: Pros
Year	Comment
2013	While the boosted four has a clear performance advantage, the swap was motivated primarily by the push for better fuel economy. EPA ratings are 21 mpg city, 28 highway, vs. the 2012 six's 19/25. An Audi Q5 comes close, 20/28, but with 211 horsepower isn't as strong. Despite weighing about 400 pounds less than the X3's 4,112, a Ford Escape with a similarly spec'd engine does no better. A Mercedes GLK350? 19/24. The Volvo is even worse. Compared to cars, the X3 doesn't fare as well. The roomier, nearly as heavy 528i rates 22/33. The crossover's larger frontal area and higher ground clearance take their toll as speed climbs. In our real-world sub-freezing suburban driving, the trip computer usually reported about 21 once the engine was warmed up, matching the EPA rating and quite good for a powerful, two-ton, all-wheel-drive vehicle. Engage an aggressive Eco Pro mode for a Prius-like throttle response and ultra-low rpm shifts, and mid-20s are easily achievable while high 20s are possible. I even observed 32 over one short trip where the lights were in my favor. But the cars behind you won't be happy. Conversely, enjoy the turbo at every opportunity and fuel economy will fall into the teens. A defeatable standard auto start/stop system operates a little more smoothly than in last year's 3-Series, but not as smoothly as it ought to. see full BMW X3 review

2007	4dr SUV 260-horsepower 3.0L I6 6-speed shiftable automatic AWD	We get 22.5 mpg consistently in overall averaging and 26 to 27 on open road trips. see full BMW X3 review

BMW X3 Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2009	4dr SUV 260-horsepower 3.0L I6 6-speed shiftable automatic AWD	Have noticed as low as 10 mpg in start and stop city driving. Average for daily driving is 14 mpg. It uses premium fuel so driving this car is already very expensive. see full BMW X3 review
2006	4dr SUV 225-horsepower 3.0L I6 5-speed shiftable automatic AWD	City driving fuel economy is not bad for an SUV. I average around 16MPG battling heavy traffic and my need for �enjoying using the accelerator�. Highway mileage is not so great. Cruising at 70-80MPH returns around 22MPG. see full BMW X3 review
