McLaren has today unveiled the 600 ‘Longtail’, which will now sit atop the British brand’s Sports Series model lineup.
Only the fourth McLaren to ever carry the Longtail name, the new 600LT features a silhouette elongated by 74 mm; updated bodywork that includes a new front splitter, side sills, extended diffuser and fixed rear wing; and top-exit exhaust tips, which, arguably, form the car’s most unique design element.
In total, more than 23% of parts are claimed to be different on a standard 600LT compared to a 570S Coupé – the car upon which it is based.
And despite being powered by the same twin-turbocharged, 3.8-litre V8 engine featured in the 570S, the 600LT gets an uprated cooling system and reduced back pressure in an exhaust system that is said to be even shorter and more extreme than that of the recently-unveiled McLaren Senna hypercar.
As a result, the 600LT is claimed to generate a peak power of 592 bhp and maximum torque of 457 lb-ft, representing a boost of 30 bhp and 14 lb-ft respectively.
The 600LT is also a lot lighter than the 570S, achieving a weight reduction of 96 kg – thanks largely to new carbon-fibre bodywork. And when kitted out with optional extra lightweight components, the dry weight of the new 600LT is claimed to be as low as 1,247 kg.
McLaren says volume of the new variant will be strictly limited, with production set to begin in October 2018 and lasting only for around 12 months.
The company first revived the LT badge at the Geneva motor show back in 2015, with the launch of the 675LT Coupé. After the production run of Coupés sold out, McLaren created the 675LT Spider, all 500 examples of which were said to have been sold within just two weeks.
All of the recent LT variants hark back to the original – the McLaren F1 GTR Longtail race car that took victory in five of the 11 rounds of the 1997 FIA GT Championship and finished first and second in the GT1 class at the 24 Hours of Le Mans.
