MY WEEK IN CARS

Murray shows off his T33 and talent for making the complicated sound simple

MONDAY

To Gordon Murray Automotive’s spacious new headquarters in Surrey to view the svelte T33 supercar (see p6) in an underground car park that will become a heritage museum when the architects and builders have finished with it.

To my eye, this is Murray’s finest effort yet for simple beauty, its flowing lines made possible by a new underbody aerodynamics system called Passive Boundary Layer Control, discovered during development of the previous T50.

The PBLC concept is a bit of a brain-stretcher, but luckily Murray is unmatched at explaining stuff to simpletons. The T50’s lower-level downforce is created in an underbody air channel that can be more aggressively shaped (therefore effective), because the rear-mounted fan is on hand to suck ‘dirty air’ out of the way via a strategically placed duct. The aero team found that by using a similar duct in the T33 and powering it with suction created at speed behind the car, they could generate 30% of the fan car’s downforce and eliminate any need for strakes, skirts and slots. It’s easy when you know how.
