Gordon Murray - the man behind the McLaren F1 - has revealed an all-new city car with big aspirations to become a truly viable alternative to today's vehicles.

Gordon Murray Designs - the design studio driven by the man who designed the 231 mile-per-hour-capable F1 supercar 20 years ago - has taken the wraps off of an all-new city car, the T.25.

The T.25 utilizes a unique 1+2 seating arrangement which allows this diminutive little city car the ability to sit three adults, with the driver sitting front and center, just like the McLaren F1.

Unlike the McLaren F1, however, this little car uses a rather anemic 660 cc, three-cylinder engine which produces 51 horsepower and 42 lb-ft of torque. Although the T.25 weighs in at only 1,265 lbs, the very eco-minded powertrain can only propel this three-seater from zero-to-62 mph in a rather leisurely 16.2 seconds, topping out at a respectable 90 mph.

Murray has released only one figure regarding the fuel economy of the car, which is a combined rating of 74 miles per gallon, a figure that is likely based on both the European cycle and an Imperial gallon, meaning a U.S.-spec car tested with EPA standards and the U.S. gallon would drop fuel economy to the realm of high 40s to 50s.

How does the T.25 compare to the Smart FourTwo?

The obvious competition for the T.25 comes from the Smart ForTwo, which is a two-seater with a standard seating arrangement. The T.25's exterior dimensions measure 240 cm long and 130 cm wide, which puts it 30 cm shorter and 26 cm narrower than the already small ForTwo. Yet, despite the size disadvantage, different interior packaging gives the T.25 the ability to fit an extra adult, and even offers more storage room.

In addition to using a unique seating arrangement, this city car also uses a front-hinging single door, which lifts up and forward similarly to older cab-over trucks when their engines were being serviced. This innovative design allows for a smaller footprint, and the ability to park three T.25 cars in a single standard parking spot.
