Supercar Icons – 1969 McLaren M6GT vs. F1 vs. P1 – Style and Specs Compared

[Orig Published on: Dec 30, 2013 @ 19:14

Only one of these LT1-powered road cars was officially made by McLaren. At the time, “by McLaren” literally meant that Bruce’s racing crew had created a road car for the boss.

The saying goes that the original M6GT was his daily driver: attending events and developing the production plans of this racing prototype for the road.

His plan was for a run of 250 cars, but only three more were created by Trojan, a fellow racing shop with the ability to complete the street-legal fiberglass bodywork, doors, and all the other trimmings like wipers and blinkers.

It was a learning process – as evidenced in the parking lights integrated into the nose, but the flip-lamps above having a slight finger hole in their leading edge.

Yep, these were functional: to lift and lock the lamps into their open position. The Trojan cars featured a shrouded lamp setup.

The M6GT is clearly a long-body prototype, with the shape still echoed in the F1 LM’s extra length versus the standard F1.

There is clear lineage in the McLaren road car family – particularly how the overlay images are so close for the M6GT versus the F1 versus the P1.

They are very, very close – despite quite different wheelbase lengths.

Aside from the strikingly-similar sihouettes and daylight-openings, the M6GT really shows progress in aerodynamics by dropping the back glass altogether in the F1 and P1.

The P1 in particular seems to almost create a negative space in this shape – it looks like there should or could be glass there, but it is pure air.

Additionally, the tail of the P1 is quite special versus the F1 and M6GT. The effectiveness of its scoop-shaped, push-rod actuated spoiler allows the tail to be far more rounded than possible before.

What all three of these McLaren’s also share is the swing-switch door that includes part of the sill frame in its lower edge for all McLaren’s so far.

For the M6GT, the doors are fairly terrifying in how little space they allow a driver for access.  Of course, by this time, Bruce could have leapt in the window slit from ten paces.

Or perhaps not. The M7 follow-up to this car is an open-wheel racer with no doors at all.
