An electric version of the car will follow

A former Formula One engineer has developed an ultra-compact city car, called the T.25, that is even smaller than a Smart car and averages about 74 mpg. The T.25 was designed by Gordon Murray and his team in Shalford, south east England. It took them three years to complete the design, and many features on the tiny vehicle reflect those used on one of the most famous “supercars” ever built: the McLaren F1

Murray's T.25 has a top speed of 80 mph, s only four-feet-wide by eight-feet-long, and has a turning radius of six feet. The vehicle features a central driving position and central instrumentation/controls, much like the McLaren F1, and offers a customizable interior that can set up six different ways to either seat two people in the rear or use it for cargo space.

Weighing in at only 550 kilograms (1,200 pounds), the T.25 is an easily maneuverable car that was developed with Formula One technology, materials, and philosophy, which makes the vehicle parts easy to replace in case of an accident. Also, the side mirrors are placed within the overall width of the car making it more difficult to lose them, and the fuel caps are on both sides of the vehicle for convenience. The sale price for a T.25 is set at $9,000.

In addition to the T.25, Murray has also developed two other new concepts: the T.27 and iStream. The T.27 is the T.25's electric relative with a range of 80-100 miles and has a price tag of $18,000. Currently, this is the only information available on this model.

According to Murray, iStream completely changes the way the manufacturing process is designed by simplifying the auto assembly line. The iStream will "allow all major components to be fitted directly on to the chassis prior to the body panels," which are pre-painted as well, and this streamlining could ultimately lead to smaller and more efficient auto plants that will reduce carbon emissions with the vehicles they're producing. 

The iStream was analyzed by Holger Erker, managing director of the German engineering consultancy IPE Engineering, and showed plenty of interest in the new idea.

"It is the most radical change in, let's say, the last 100 years of car body making," Erker said. "With iStream, one of the most cost intensive production steps -- body panel press shop -- is completely eliminated." 

Murray worked as a Formula One designer from 1969-2006. In 2007, he opened the Gordon Murray Design consultancy. He won the "Idea of the Year" award in November 2008 at Autocar Magazine's annual awards ceremony for his proposed manufacturing process (iStream) for the T.25.

RE: MPG is misleading

Gallons per mile is unwieldy. To figure out how many gallons over a trip you're looking at a large multiplication of a fraction, and gas is sold by the gallon not by the fractional gallon per mile.

Even to figure out the absolute dollar amount is a mess of a calculation where you have to plug in an exact number to start off with. With MPG you can just multiply by 1000 as in 30MPGx1000=30,000 miles = 1000 gallons x gas price (say $2.65)= cost over 30k miles. ($2,650) Easy calculation.

Compare to .033 gpm. What are you going to multiply this by? 50,000 gives you... uhhh... let's see... 15, plus 1 so 16, 5, move decimal over, uhhh... 5 places; but it's really 0.033333333 so that'd be.... 166666666666, but decimal goes where? I'd say 1666.666 gallons just becuase that looks right. Now multiply by gas @ $2.65/gal...
Right, like I'm gonna do that in my head.

MPG is still best because fuel costs are a significant portion of car ownership regardless of whether you have a truck that gets 15mpg or a car that gets 35, so the percentage reduction still tells you the percentage in felt costs. If we were talking about 300MPG cars it'd be a different story -- fuel costs can be ignored at that level.
