McLaren Senna GTR LM celebrates firm's historic Le Mans win

You may remember the British team has itself launched its own run, the LM25, to mark the anniversary, but McLaren's work is different as it's focused purely on the Senna GTR, turning each into a convincing homage.

Aside from the tailored livery, each Senna GTR LM also receives a "1 of 1" plaque that has the details of the corresponding 1995 Le Mans F1 GTR unit inscribed for matching eternity onto the carbon fiber sill along with the matching VIN number of the modern auto.

The strikingly finished green and yellow Senna GTR LM is painted to match the third-place F1, known as "the Harrods car", while the iconic Gulf livery on vehicle number 825/2 is a faithful recreation of the auto that came home in fourth.

All of them have a specific target - honor the matching five McLaren F1 GTRs that went down in racing history with their 1st, 2nd, 4th, 5th, and 13th finishes at the 1995 Le Mans. So detailed is the work that each auto takes more than 800 hours to paint. All five are kept as close to the originals as possible, as McLaren coordinated with the Le Mans organizer to get permission to re-create every last detail of the logos and trademarks on the cars. The authenticity continues with a faithfully reproduced scrutineering sticker fixed to each car's roof.

It isn't just the appearance that received all the attention, though. Brownie points are earned with the ramping up of twin-turbo 4.0-litre M840TQ V8 to 845hp, a 20hp boost over the "standard" GTR, and the adjustment of torque curve so torque hits harder from lower revs. The rev limit has also increased from 8,250 rpm to almost 9,000 rpm.

To help achieve that, the motor gets valve spring retainers made from metal matrix composite (MMC), reducing their weight by 65 per cent, higher grade steel for the valve springs and hand-polished, CNC ported cylinder heads. A recalibration of the whole powertrain takes advantage of these new parts, leading to the increase in power.

Small changes abound elsewhere in the vehicle, too.

Further bespoke F1-inspired touches include a specially designed exhaust outlet, bespoke five-spoke wheels from OZ Racing and gold brake calipers and suspension wishbones. The new two-door will stick with rear-wheel drive and eventually spawn an M2 variant. We're afraid to know the prices for these five cars, but we won't know anyway, because McLaren hasn't released that information.

The five buyers of these cars will receive tickets for a VIP visit to the 2021 24 Hours of Le Mans race, with the opportunity to drive their vehicle on track on the morning of the race.
