It doesn't come as a surprise to see YouTuber Mr. JWW making full use of his fixed-roof Longtail - his McLaren 675 LT, when assisting his friend pick up his McLaren 675 Longtail Spider Carbon Series baby. Extensively optimized within the in-house wind tunnel at the McLaren Technology Center is the 675LT (Longtail) with an astonishingly potent race-proven engine that produces 675 (666bhp) and 700Nm (516lb-ft), and the suspension system engineered for even sharper responses.

Coming from the MSO (McLaren Special Operations) division, the Carbon Series badge is only installed to 25 LTs, with these cars coming on top of the 500 standard cars built by the British company, if the 675 Longtail Spider may be called so, says autoevolution. What has not changed is the McLaren 675LT's powerhouse. A 666-horsepower, 3.8-liter, twin-turbo V8 remains running. McLaren has not published any performance metrics or the MSO Carbon Series LT, but the replacement of the painted body with an exposed carbon-fiber should result in a healthy drop in weight, which, should in turn, improve acceleration, braking, and handling, says autoblog.

The Carbon Series LT looks breathtaking in the real-world clip. Its special edition means an extra 40 percent of the panels being made of the wonder material, carbon fiber. The added goodies include the folding roof and the rear seating compartment, hood, A-pillars, front and rear wings, side blades, as well as the fuel filler door. The aero-crazy front bumper, from the 650S GT3. The glossy finish turns it into an eye candy.

It has been 12 months since Mr. JWW started his YouTube's "supercar antics". He said he wanted to share his adventures with like-minded "petrol heads" and supercar fans. He has travelled the world and featured everything from Pagani to Porsche, Lamborghini, Ferrari, and McLaren and even a carbon fiber Bat mobile on the Gumball 3000! Check out his video below.
