Porsche was introduced at the Frankfurt Show as the Type 901. However, it was not until
last summer that I had a chance to drive a prototype, which impressed me very much with
its handling and performance, although the carburation was not right.
More recently, I have been trying one of the first production models whose type number has now been changed to 911. I found it to be a great improvement in every respect. Like all Porsches, it is a rear-engined car using an entirely new overhead cam, aircooled, flat sixcylinder engine. This is a 2-litre with a bore of 80mm and stroke of 66msn. With a compression ratio of 9 to 1, it gives 130 b.h.p. net (150 gross) at 6,100 r.p.m. Maximum torque is l3Olb ft at 4,200 r.p.m. The engine is fed by special triple-barrelled Solex carburettors.
The 911 bears a definite fansily resemblance to other current Porsches, yet its lines are quite different. It looks sharper, with a more square front and rear and has a longer, lower appearance. The slim, wrap-round bumper emphasizes the clean lines. With a wheelbase nearly 5in. longer than the current fourcylinder Porsche (7ft. 3in instead of 6ft. lOin) room has been gained inside, and the 911 can now be called a 2 + 2. I would not say that two people sitting in the back would be very comfortable, but they can sit there. Other comparative dimensions show a gain of more than an inch in overall width and front and rear tracks.
Handling is neutral with very little body roll. There is not much rear-engine oversteer.
The height is roughly the same at 4ft 4in. With a total
overall length of l3ft 6.7in. the new car is ezactly 5in. longer.
