The GT is priced from RM908,000 (before taxes, duties and options) and maintains the use of a 4.0-litre (3,994cc) high-performance twin-turbocharged M840TE 90-degree V8 mill at the rear of the cabin that powers the rear wheels.
Other goodies added include an Eco start-stop system with deactivation switch, low twin exit stainless steel exhaust system, twin multi-plate clutches and four driving modes of Non-Active, Comfort, Sport and Track.
At 1,530kg (kerb), the GT has a wheelbase of 2,670mm and standing at 4,683mm-long, 2,095mm-wide (3,286mm with both doors open) and 1,213mm-tall (1,234mm with lift system).
The mid-mounted engine provides 620PS at 7,500rpm and 630Nm of torque from 5,500 to 6,500rpm and the output is managed by a seven-speed Seamless Shift gearbox that sends the "twist" to an open differential with McLaren's Brake Steer system.
This allows the GT to sprint from 0 to 100kph in 3.1 seconds before reaching a top speed of 326kph.
The black with silver printed McLaren logo four-piston aluminium callipers, found at all four corners of the GT, bite down hard on the large cross-drilled iron discs all-round to bring it to a complete stop from 100kph in just 32m (from 200kph - 127m).
Suspending the Carbon Fibre Monocell II- T monocoque with carbon fibre rear upper structure are double wishbones with proactive damping control and anti-roll bars for added rigidity.
For grip, the 20 (front) and 21-inch (rear) silver seven-spoke cast alloy wheels are wrapped with 225/35 and 295/30 Pirelli P Zero tyres respectively and can be checked via a tyre pressure monitoring system (TPMS) and tyre temperature gauge.
In terms of driver aids, the GT is graced with an antilock braking system, traction control, dynamic electronic stability, launch control, hill hold assist, cruise control and an electronic parking brake.
Externally, the GT gets fitted with dihedral doors with soft-close function, glazed rear tailgate with soft-close function, heated door mirrors
with "dip" function when in reverse, and automatic wipers.
For lighting, it comes equipped LEDs for its automatic headlights with levelling function, time-adjustable follow-me-home function, sequential indicators, daytime running lights and dual-function rear fogs/reverse light.
To give the GT some style are its silver exhaust finishers, gloss black bits that include the front splitter, side sills, rear diffuser, fixed roof, cantrails and the rear lower bumper section.
Matching the body colour (whatever its owner wishes it to be), are the rear spoiler, door mirror casings and door mirror arms while the belt moulding/rear fender closures and exterior upper window surrounds are in Satin Black.
Inside, the driver-centric cabin gets wrapped in leather (a combination of Nappa leather and leatherette) while featuring manually adjustable seats, anti-dazzle electrochromic rear-view mirror and dual-zone climate controls, keyless entry with push-start button and a total of 570 litres worth of boot space (front-150 and rear-420).
The driver gets easy access to the four-speaker sound system with a 7.0-inch portrait touchscreen that has functions that include radio, Bluetooth, USB port, AUX-jack, voice-control, iPod/iPhone integration and navigation - all while a 12.3-inch TFT instrument cluster stares back.
If that isn't enough, then it's time to delve into the extensive options list that will boost the purchase price after choosing one of 30 exterior colours (or perhaps a combination), before deciding which of the three lightweight 15-spoke forged wheels to go with.
There are also four colour options for the brake callipers and, if deemed necessary, three other colour options for the six-piston (front) and four-piston (rear) callipers of the carbon-ceramic brakes.
Furthermore, the interior can be further customised with power-adjustability for the seats (with memory function) and steering wheel.
Afterwhich, perhaps Softgrain Aniline leather with Alcantara accents could be used to wrap the seats and steering wheel, before installing some piano gloss-black inserts, extended knurled aluminium paddle-shifters and a brushed satin silver steering wheel clasp.
Also included in the list of optional extras is a vehicle lift-system, reverse camera, power-folding mirrors, rear luggage-bay privacy cover, gloss-finished carbon fibre exterior, panoramic privacy tinted glass roof and a 12-speaker Bowers & Wilkins sound system among others.
"The new McLaren GT represents the latest addition to the model range. It is an exceptionally refined vehicle with class-leading elegance and sophistication. Designed for clients with a sense of adventure, who are seeking both performance and continent-crossing capability," said McLaren Automotive managing director (Asia Pacific and China) George Biggs.
The launch of the GT was held at the new 420 square-meter McLaren Kuala Lumpur facility in Glenmarie, Shah Alam which provides sales, after-sales, accessories and servicing for the brand's full range of vehicles.
