The Geneva Motor Show might be cancelled,
but that hasn’t stopped McLaren from unveiling the all-new 765LT. Set to become
the latest Longtail model, the 765LT is a lighter and more powerful take on the
already impressive 720S.
In typical fashion, the car has been given
a carbon fiber intensive aerodynamics package. It includes an extended front
splitter, modified bumpers and revised skirt skirts. The model also has unique
door blades, a larger diffuser and an active
Longtail rear wing.
The latter is the car’s most distinctive
feature and it aids powertrain cooling by drawing hot air out of the engine
bay. It also features an airbrake function and a variety of settings which
either optimize downforce or reduce drag. Besides the unique rear wing, the
765LT has ultra-lightweight forged alloy wheels with titanium bolts. They’re
wrapped in bespoke Pirelli P Zero Trofeo R tires.
The 10-spoke wheels are backed up by a
carbon-ceramic braking system with calipers sourced from the Senna. If that’s
not impressive enough, buyers can opt for a track brake package which features
bespoke brake pads and carbon-ceramic discs from the Senna. The latter are
roughly 60% stronger than the conventional carbon-ceramic discs and offer four
times better thermal conductivity for reduced wear and fade.
Out back, there’s a ventilated rear fascia
and a four-tailpipe titanium exhaust system which is 40% lighter than a
comparable steel setup. Besides the weight savings, the system delivers a
“searing LT soundtrack.” The performance focus extends to the cabin as drivers
will find carbon fiber-shelled racing seats that are a combined 18
kg)lighter than the sports seats used in the 720S. Speaking of weight saving,
the air conditioning and audio systems have been removed and there’s
lightweight nets instead of door storage pockets. However, these items can be added upon
request.
Other highlights Alcantara upholstery, a
carbon fiber floor and an 8-inch infotainment system. There will also be a
wealth of customization options and eight bespoke ‘By McLaren’ color themes.
One of the more interesting options is a double-glazed panel which provides a
glimpse of the car’s V8 engine. It is integrated into the model’s carbon fiber
structure and features 765LT badging as well as a carbon fiber surround.
Power comes from a twin-turbo 4.0-liter V8
engine that has been equipped with forged aluminum pistons, an additional fuel
pump, a revised oil pump and a recalibrated engine management system. Thanks to
these modifications, the mill produces 755 hp and 799 Nm of torque – 45 hp and 30 Nm more than the
720S.
The powertrain upgrades don’t end there as
the model has a seven-speed dual-clutch transmission with optimized gearing.
This change allows for “15% quicker in-gear acceleration than a 720S and the
fastest lap times of any McLaren Super Series model.”
Speaking of the gearbox, it features a new
“limit downshift” function. When a driver wants to downshift but the change
would over-rev the engine, the request is remembered and then executed when the
“engine speed and road speed can be harmonized.” In terms of performance, the
765LT can accelerate from 0-96 km/h in 2.7 seconds and 0-200 km/h in 7.2 seconds. The model can also run the quarter mile in less
than 10 seconds and hit a top speed of 330 km/h.
Those are some impressive numbers and the
performance can be chalked up to a variety of factors including the model’s
lighter weight. McLaren says the car weighs 79 kg less than the 720S
and has a dry weight of just 1,229 kg. This means the 765LT is more
than 50 kg lighter than its “closest competitor in comparable
specification.” McLaren’s obsession with weight savings went so far that they
reduced the thickness of the side window glass for the first time on a
modern-day LT. The front windscreen is also thinner, while the rear uses
lightweight polycarbonate.
Elsewhere, the 765LT has a retuned
suspension with new springs and dampers. The model also sports a wider front
track, a lower front ride height and a Proactive Chassis Control II system with
updated software that promises “even greater precision and control.”
Furthermore, the steering system has been “further honed with a quicker ratio
and a stiffer torsion bar for even purer driver feedback.”
