McLaren Senna GTR LM celebrates Le Mans win

McLaren's bespoke MSO division has pulled the drapes off five customer-commissioned McLaren Senna GTRs that pay tribute to the British car-maker's famous F1 GTR win at the 1995 Le Mans 24 Hour race.

The handful of special McLaren hypercars each carry the Senna GTR LM nameplate in reference to the F1 GTR LM that took first, second, fourth, fifth and 13th in the world-famous endurance race held 25 years ago, with each car featuring a one-off paint job inspired by the original racers.

Each car is claimed to take an incredible 800 hours to paint, and MSO says it had to gain permission from each of the F1 GTR LM sponsors before work could officially commence.

The only sticker worn by each Senna GTR LM is a piece of vinyl applied to the cars that replicates the original F1 racecars' scrutineering sticker.

The other unique design elements that feature on the special Sennas include five-spoke OZ Racing alloy rims and gold paint used on the brake callipers and suspension wishbones.

The modern McLaren hypercar also features special exhaust tips that pay homage to the original F1, while inside there's a racing steering wheel, gold shift paddles and buttons, plus leather door pull straps and embroidered headrests.

The commemorative Senna GTR LMs also receive some mechanical changes that include lightweight valve springs, a freer-flowing Inconel exhaust and hand-polished CNC ported cylinder heads that, along with a remap and other changes, raise the rev limit from 8250rpm to a stratospheric 9000rpm.

Power rises from 607kW to 621kW.

If you're wondering which is which, the Senna that wears the race-winning F1 GTR LM livery is the charcoal-grey model that carries the Japanese Tokyo Ueno Clinic sponsor (which incidentally specialised in penis enlargement in the mid-1990s).

Originally driven by Yannick Dalmas, Masanori Sekiya and JJ Lehto, the special MSO McLaren also replicates the winning car's extra driving lights.

The Harrods green-and-yellow Senna GTR LM is painted to match the third-placed F1, while the F1 painted in the Gulf livery matches the car that ended the race in fourth.

The fifth and 13th-placed Senna GTR LM feature the Elf and Cesar Baldaccini-designed liveries.

Unveiled last year, the McLaren Senna GTR incorporates even wilder aerodynamics than the road version, including a wider front and rear track, larger front spoiler and huge front splitter.

There’s also front dive planes and cool sill-mounted vortex generators.

At the rear of the car there’s a completely redesigned diffuser and a repositioned active rear wing.

Following many more hours in the wind tunnel, the McLaren Senna GTR generates 1000kg of downforce at 250km/h – 200kg more than the road car –  while under braking it can pull 3g in deceleration – 20 per cent more than the road-legal Senna.

According to McLaren, only an F1 car is quicker than the Senna GTR around any given circuit.

Originally priced at £1.1 million ($A1.95m), it's not known how much extra it cost to commission MSO to create the GTR LM versions.
