McLaren has officially unveiled the new 675LT Spider following a leak earlier today.

Created in response to "significant customer demand," the 675LT Spider follows in the footsteps of the 675LT Coupe and features a sportier exterior with a larger front splitter, new side skirts, and an active Longtail airbrake that is 50 percent larger than other Super Series models.  The high-performance convertible also has a titanium dual exhaust system and unique 19- / 20-inch ultra-lightweight forged alloy wheels with special P Zero Trofeo R tires.  Of course, the car's defining characteristic is the retractable folding hardtop which can be opened at speeds up to 30 km/h (19 mph).

The lightweight theme continues in the cabin as the model has been equipped with lightweight carbon fiber-shelled racing seats that are covered in leather and feature 675LT embossing.  The car's air conditioning system has also been removed but it can be ordered as a no-cost-option if you don't mind adding an additional 16 kg (35.2 lbs) of weight to the car.

Power is provided by a "heavily revised" twin-turbo 3.8-liter V8 engine that features new turbochargers, revised cylinder heads and modified exhaust manifolds.  The engine also has a new crankshaft, lightweight connecting rods and a high-flow fuel pump.  Thanks to these modifications, the engine develops 675 PS (666 bhp / 496 kW) and 700 Nm (516 lb-ft) of torque - 25 PS (24 bhp / 18 kW) and 22 Nm (16 lb-ft) more than the 650S Spider.

The extra power doesn't sound like much but it enables the 1,270 kg (2,800 lbs) convertible to accelerate from 0-100 km/h (0-62 mph) in 2.9 seconds and 0-200 km/h (0-124 mph) in 8.1 seconds.  Given enough room, the 675LT Spider will eventually hit a top speed of 326km/h (203mph).

To keep things under control, the car has been equipped with a sport-tuned suspension which features stiffer springs and a wider track.

Production will be limited to 500 units and pricing starts at £285,450.  The first deliveries are scheduled for the summer of 2016 and potential customers better act quick as the 675LT Coupe sold out in a couple of months.
