Some of the latest Mercedes have 7 speed AUTOS in them.
I have a 95 Subaru auto that gets an average 27.9-mpg at an average speed of 51 mph on an average 127 mile daily drive.
On the other hand, the Subaru STi has had a 6-speed manual in it since 2004. Sti’s have stock hp numbers of 305 hp and get a highway average 27mpg.
The ESX STi's I work on get slightly less mileage. The first is a street legal AWD STi with a 2.5 liter turbo charged engine that churns out 1,042 hp and runs the Quarter mile in 8.91 seconds at 154+ mph on street tires with a full interior, exhaust, power windows and a curb weight of 3,262 lbs. This vehicle is fully street legal except for catalytic converters, its fuel mileage is about 1.84 gallons of VP import gasoline (125 octane fuel) per Quarter mile. It is well known as the worlds fastest Street tired STi with 18 national NHRA championships and 2 NHRAÂ world championships in 2 years.

It runs 7.60 second quarter mile passes at 176 mph. Its fuel consumption is about 2.6 gallons per quarter mile pass. This vehicle is the fastest AWD Subaru in the world.Â
  Some Stats. Pro car
The engine spins at 9,300 rpm and uses 3 injectors per cylinder to supply fuel .One of the three injectors is used to spray a cooling charge into the intake to cool the intake valves. If the engine is shut down at the finish line the valves will bend from being white hot. The turbo's inlet is 101 mm in diameter. Nitrous oxide is used to spool the turbo at the line. The turbo spools to 50psi, which is full boost in just under .68 seconds. The power produced is transmitted through a slightly modified Subaru 4 speed automatic trans (AWD 4-EAT). The pro car uses 30 lbs of ice per quarter mile pass in its intercooler.
