2017 McLaren 675LT Spider opens up

By Bob Nagy on December 7, 2015 4:24 AM

Following hot on the heels of its just-released and already sold-out 2016 McLaren 675LT Coupe, the performance-focused British automaker has taken the wraps off its al fresco sibling, the new 675LT Spider. Set to debut at the Geneva Auto Show in March, this latest member of McLaren's "Super Series" family also is based on the 650S. Like the Coupe, it will have a limited run of just 500 units with deliveries beginning next summer. Here in the U.S. the new Spider will open at $376,700 -- $32,100 more than its hard-shell counterpart. For that tidy sum, buyers are being promised "the most focused, fastest and exhilarating open-top model to ever wear a McLaren badge."

Open invitation to exhilaration

Created in response to customer demand, the McLaren 675LT Spider's design closely aligns with that of the "Longtail" Coupe variant. The same carbon-fiber intensive construction and MonoCell core reduces mass and eliminates the need for any added bracing or reinforcement in this open-top model. While curb weight is up by about 88 pounds compared to the 675LT Coupe, the car still tips the scales 220 pounds below a 650S Spider. Crowning the new 675LT Spider is a three-piece power folding hardtop that tucks beneath a color-keyed tonneau. It can be cycled at road speeds up to 19 mph. Other Spider-specific bodywork changes include a revised active "Longtail" Airbrake that's 50 percent larger than on other Super Series models.

Although the bespoke McLaren 3.8-liter twin-turbo V8 engine in the 675LT Spider makes the same 666 horsepower and 516 lb-ft of peak torque as in the Coupe, over half of the components -- including the turbos, heads, exhaust manifolds, camshafts and connecting rods -- have been revised to ensure optimum drivability. Linked to McLaren's 7-speed SSG sequential transmission drivingthe rear wheels, the engine sends the Spider streaking to 62 mph in 2.9 seconds -- just 0.2 tick off of the Coupe's time -- and tops out at 203 mph.

Track-focused edge 

While these two McLarens share the same suspension bits and geometry, the Spider's chassis is the most track-focused of any Super Series car. Spring rates have been increased by 27 percent up front and 63 percent in the rear, changes that shift dynamic balance aft and raises downforce by 40 percent over the 650S. The 675LT Spider also wears the lightest wheel/tire combo ever offered by McLaren, wrapping Pirelli P Zero Trofeo rubber around unique 19-inch front/20-inch rear 10-spoke forged alloy rims. 

Inside, the 675LT Spider's appointments parallel those of the Coupe. Alcantara and raw carbon fiber dominate the light-makes-right motif which features leather-trimmed shell-style racing seats, a center touchscreen display and a 4-speaker Meridian sound system. Buyers can choose or lose the 35-pound climate control system, which is on offer as a no-cost option.
