Making a grand debut at the 2015 Geneva Motor Show, McLaren has revealed the excitingly hot ‘675LT’ that will leave you in awe in more ways than you can imagine. Essentially, the high-performance variant to the 650S, the 675LT is lighter, faster and also pays homage to the radical 1997 McLaren F1 GT “LongTail” homologation special. Yes! that’s what the LT stands for.
The McLaren 675LT is a completely track-focused sports car although legal enough to be driven sanely on public roads. The Brits have added lengthened bodywork with its tail only grown longer by a few millimeters along with the longer carbon chin splitter at the front and the slightly longer new active spoiler at the rear, part of the new aero kit for enhanced downforce. The cute (a term not frequented around sports car) smiling fascia resembles the flagship P1 but is more of a devilish smirk when seen along with the massive air intakes.
Much like the 650S, the lines on the McLaren 675LT aggressively push back and add to the aerodynamic design of the sports car. The highlights on the side profile are the massive air intakes covered in carbon, resting behind the doors and provide cool air to the soul steering V8 engine. Coming to the rear, the 675LT is quintessentially McLaren and we love every bit of it. Covered in carbon-fibre, you have the flat LED tail lights at the rear with the large twin exhaust unit residing in the centre. The new exhaust system has been made out of forged titanium that has contributed a healthy 1.1 kg of weight savings. Fun fact! The exhaust tip will also turn blue permanently on extreme heat. That’s exactly the kind of bragging rights the 675LT gives you after a hard day at the tracks.
Reminiscing the F1 LongTail, the McLaren 675LT has also seen a massive reduction in weight losing a healthy 100 kgs compared to the 650S. If you haven’t guessed it already, much of the weight reduction has come by swapping parts which include body panels, drivetrain parts, chassis and body structure parts that have been replaced with lighter alternatives. The windscreen is also thinner. Weight has also been saved, courtesy of the carbon-fibre bucket seats taken from the P1 that have been upholstered in the very expensive Alcantara leather. The interior also misses out on the AC unit as a weight saving measure though buyers can opt for it as a no cost option. The 675LT now measures a healthy 1230 kgs (dry) with the power-to-weight ratio standing at 541 BHP per tonne.
McLaren says that it has changed almost half of the parts on the 3.8-litre V8 twin-turbocharged engine compared to the 650S in order to extract more power, torque and driveability. Changes include new lightweight turbos, changed cylinder head and exhaust manifolds along with lighter connecting rods and a faster fuel pump that does not cut off fuel supply during gear changes. With the extensive amount of changes, the 675LT now produces a satanic 666 BHP of power or 675 PS (hence the name) and 700 Nm of torque, paired to the same 7-speed dual-clutch automatic gearbox.
Quickly speaking about times, the 675LT can do the 0-100 kph run in 2.9 seconds while the top speed can be maxed out at 330 kph. The lighter McLaren has also been lowered by 10 mm and gets 2 mm wider than the 650S to offer a track friendly set-up. The Proactive chassis control from the 650S has been carried over and comes with 3 modes – Normal, Sport and Track. Stopping power on the 675LT comes from the massive 394 mm at the front and 380 mm at the rear ceramic brakes that are accompanied with 6-piston calipers mounted on forged aluminium hubs. Finally, all that power is sent to the 19-inch (front) and 20-inch (rear) alloy wheels wrapped in Pirelli P Zero Trofeo R tyres that are designed especially for the track.
At £259,500 (Rs. 2,44,99,334 without taxes), the McLaren 675LT doesn’t come in as ‘affordable’ even by a long shot and with production limited to only 500 examples, the folks at Surrey will have the uber rich lining up outside for purchase in no time. Deliveries of the 675LT will start globally by July this year.
