McLaren presenterar 675LT
Lättare, snabbare och vassare

McLaren presenterar nu den nya modellen 675LT som kommer att ha sin premiär på bilmässan i Genève nästa vecka. Bilen bygger vidare på 650S men blir lättare, snabbare och vassare på alla sätt och vis. LT står för Longtail och modellen kommer endast som coupé.
Motorn är fortfarande en dubbelturbomatad V8:a på 3.8 liter men över 50 % av delarna ska vara nya. Den lämnar som namnet avslöjar 675 hästar och till den kopplas en sjustegad SSG-låda. 0-100 km/h ska gå på 2.9 sekunder, till 200 blås tar det 7.9. Toppfarten anges till 330 km/h.
100 kilo har man lyckats banta bort och detta bland annat genom att använda sig av ännu mera kolfiber. Allt från fronten som fått sig en fetare splitter till luftintagen på sidorna och hela baken är nu i detta material. Där bak hittar vi även det nya avgassystemet i titan samt den aktiva "Longtail"-vingen som är 50 % större än den 650S har, och som fungerar som luftbroms. Vågen stannar på 1 230 kilo.
Vad maskinen kommer att kosta och när den börjar säljas framgår tyvärr inte. Endast 400 stycken exemplar tillverkas och fyra av dessa kommer till Skandinavien.







































• 675LT re-establishes the McLaren ‘Longtail’ heritage, focusing on light weight,
optimised aerodynamics, increased power, track-focused dynamics and driver
engagement

• 100kg weight saving makes the 675LT the lightest in its class, and gives a
power-to-weight ratio of 549PS per tonne
• A third of parts changed compared to the 650S which it sits alongside in the
McLaren Super Series
• Significantly enhanced M838TL engine in the 675LT features more than 50
percent new components

• Global premiere at the Geneva Motor Show in March 2015 on stand 1240, at
12.15 CET (11.15 GMT)
The McLaren 675LT will make its world debut at the 85th
clear focus on performance, light weight and ultimate levels of driver engagement – all
key attributes of a McLaren ‘Longtail’. Offered as a Coupé only, the 675LT will be the
most track-focused, yet road legal, model in the McLaren Super Series, with a power
to weight ratio that eclipses established rivals. The sprint from 0-100 km/h (0-62 mph)
takes just 2.9 seconds, with controlled torque delivery ensuring optimised traction off
the line. Acceleration continues at relentless pace with the 200 km/h barrier broken in
7.9 seconds, on to a top speed of 330 km/h (205 mph).
The first images of the car demonstrate a more aggressive look for the McLaren brand
than has been seen before. Styling cues run from the extended carbon fibre front
splitter, through an extended door blade and additional cooling intake, to the circular
twin titanium exhaust pipes, giving a hint to the performance available for the most
powerful and lightest model in the McLaren Super Series. The active ‘Longtail’ Airbrake
is 50 percent bigger than the one fitted to the 650S yet, due its carbon fibre structure, is
actually lighter. This is just one of the enhancements that add up to a dry weight of just
1,230kg.
More than 50 percent of parts have been changed in the 3.8-litre V8 engine to deliver
increased levels of power, torque and driveability. Upgrades include new, more
efficient turbos, detail design changes to the cylinder heads and exhaust manifolds,
new camshaft and lightweight connecting rods, and a faster-flowing fuel pump and
delivery system. These changes are so significant, that the engine unit receives a new,
unique code – M838TL. The low weight, low inertia power unit produces, as the name
suggests, a power output of 675PS and a power-to-weight ratio of 549PS per tonne.
The 675LT is as fully track-focused as it is road legal with around a third of parts
modified to suit this purpose compared with the 650S Coupé and Spider that continue in
production alongside it. Yet, like its iconic predecessor, the McLaren F1 GTR ‘Longtail’,
from which the LT name is derived, this is a car that is as exciting to look at as it
is to drive. It also embodies the key attributes of the ‘Longtail’ ethos targeting light
weight, optimised aerodynamics, increased power, track-focused dynamics and driver
engagement.
THE KEY TO THE ‘LONGTAIL’ SUCCESS: LIGHT WEIGHT AND AERODYNAMIC
Despite the revised, longer bodywork, the 1997 McLaren F1 GTR ‘Longtail’ was over
100kg lighter than its hugely successful predecessors. As it was nearly 20 years
ago, weight reduction has been a key focus throughout the development programme
for the 675LT and, in a subtle nod to its bigger brother, the result is a saving of over
100kgs over the other models in the Super Series. This savings have been achieved
through the extensive use of carbon fibre for the body panels, along with lightweight
engine, chassis and body structure parts. In the pursuit of minimal weight, and to suit
its purposeful intent, even air conditioning has been removed, but can specified as a no
cost option.
Below a newly designed front bumper sits a prominent carbon fibre front splitter, which
works the air harder, complementing new front wing end plates to increase downforce
levels over the front bodywork. The turbulent air from the front wheel arches is ‘cleaned’
as it flows towards the rear bodywork by sculpted carbon fibre side sills which run
the full length of the lower bodywork. A subtle air intake is incorporated ahead of the
leading edge of the rear wheel arch, below a more pronounced side intake behind the
door, both of which feed clean cool air into the side-mounted radiators.
The aero balance is optimised by the active ‘Longtail’ Airbrake which, as with the
McLaren F1 GTR ‘Longtail’, is larger – 50 percent larger than on other Super Series
models. The reprofiled design flows into the lines of the new carbon fibre rear wings.
Two circular exhaust pipes, forged from titanium, exit centrally through exposed
bodywork below the rear wing. Despite a more complex design, the bespoke crossover
system is designed to optimise performance and reduce weight, saving 1.1kg. The rear
deck and sections flanking the exhaust pipes remain exposed; designed to evacuate
hot air from the engine bay as efficiently as possible, while a lightweight polycarbonate
rear screen features further louvres. A louvred carbon fibre rear bumper reduces air
pressure over the rear wheels, while the rear design is completed with a dramatic
integrated carbon fibre diffuser.
FIVE UNIQUE ‘BY McLAREN’ 675LT THEMES
The 675LT is offered in five ‘By McLaren’ hero specifications, which includes four
bespoke colours never previously offered: Silica White, Delta Red, Napier Green and
Chicane Grey are all newly formulated paint hues for the 675LT. The famous heritage
McLaren Orange completes the themes unique to the model. Each of the five ‘By
McLaren’ specifications is complemented within the stripped out interior with carefully
selected materials and colours.
The purposeful driver-focused cabin of the 675LT gives even further indication of track
potential. A pair of ultra lightweight carbon fibre-shelled bucket seats, upholstered in
Alcantara® as standard and modelled on those in the McLaren P1TM, provide comfort
and support with no compromise on overall weight. A subtle 675LT logo features on the
headrest of each seat, and is also present on the rev counter. In a change to the other
models in the Super Series, the air conditioning controls are now incorporated within the
intuitive touchscreen infotainment system.
The McLaren 675LT will make its global debut at the 85th
CET (11.15 GMT) on Tuesday 3 March 2015.
