M cLaren continues to mix the components of its sports car construction kit. The result is the new McLaren 675LT, which will celebrate its premiere at the 2015 Geneva Motor Show. The sports car joins the 'Super Series' as the new top model. The series also includes the 625C and the 650S, which are available in Asia.
McLaren 675LT depends on the 650S
When developing the new McLaren 675LT, the engineers had three overriding goals in mind. The 'longtail' should be more powerful and lighter than the 650S. And to do this, focus more on the driver. As the name suggests, the McLaren 675LT shakes exactly 675 hp from its 3.8-liter V8. The biturbo engine thus discharges 25 hp more to the rear wheels than the 650S. The maximum torque also climbed by 22 Nm to a total of 700 Nm.
According to McLaren, the increased performance is also reflected in the measured values. The new sports car runs the image sprint to 100 km /h in 2.9 seconds. With that he takes a tenth of a second off the 650S. It becomes clearer with the sprint to 200 things. Here the McLaren 675LT is ahead by half a second (7.9 seconds). As with the 650S, the British give the top speed of 330 km /h.
100 kg weight savings
Not The 'Longtail' surpasses the 650S only in terms of performance, but also in length. The McLaren 675LT extends - according to its name - over 4,546 meters, which corresponds to an increase of 3.4 centimeters compared to the 650S. The new sports car from Woking measures 1.188 instead of 1.199 meters in height and 2.095 instead of 1.895 meters in width.
Compared to the 650S, McLaren claims to have lost 100 kilograms from the 675LT. Around a third of the parts were replaced. Means: The McLaren 675LT has a dry weight of 1,230 kilograms. This gives the athlete a power-to-weight ratio of 1.822 kg /hp. The new sports car from Woking has slimmed down mainly in the areas of engine, chassis, body and exhaust. And how? By dieting with carbon.
McLaren is upgrading its new 675LT at the front with a new apron that carries a larger carbon splinter. In addition, the engineers missed the McLaren 675LT two end plates on the bumper. They should direct the air over the redrawn carbon side skirts towards the end section. In the side viewThe two additional air ducts stand out in particular. The inlets behind the doors have also been modified. They take in fresh air and transport it to the side-mounted coolers.
The designers also redesigned the rear of the McLaren 675T. The titanium exhaust system has a different shape and is 1.1 kilograms lighter than the 650S. Part of the V8's hot exhaust air escapes to the right and left of the tailpipes. The McLaren 675LT releases more hot air through the 22 slots in the plexiglass cover.
Bucket seats from the McLaren P1
The British offer the McLaren 675LT in five different paint finishes: Silica White, Delta Red, Napier Green, Chicane Gray and McLaren Orange. McLaren packs the bucket seats from the P1 into the interior of the 675LT.
Incidentally, McLaren associates the term 'longtail' with great successes in motorsport. The McLaren F1 GTR Longtail, an F1 stretched 641 millimeters in length, won a total of five of the eleven races in the FIA GT Championship in 1997 and clinched a double victory in the GT1 class at the 24h race in Le Mans.

So now they have their own GT3 at McLaren, and yes, the 675LT could certainly stir up the assembled circuit elite. The key data alone are promising, less weight, more power and so on. In the engine alone, over 30 percent of the parts are new, says McLaren. But as soon as the door swings open, the technology fades into the background. Immediately you go black before your eyes - from the sheer carbon fiber composite material. Add a few bright orange accents, yes, you can like that.
But more important: Similar to the Porsche GT3, the 675 LT tries to create the best possible working conditions for its driver. The shape of the bucket seats fits right away, their adjustment range and that of the steering wheel enable an optimal position to tackle the next lap record. Added to this is the already greatly reduced operation, which is typical of McLaren sports cars. And the fact that the British take their racetrack ambitions seriously is shown by the fact that the 675 LT will “by no means” be available as an open version. Not that bad, is it? The fact that the sports car is limited to a series of 500 copies seems more regrettable.
