3月のジュネーブモーターショー2018でデビューしたマクラーレンセナGTRコンセプト。
この時は最大で75台発売するかもとの事でしたが、正式に発売がアナウンスされ世界限定75台
価格は1億6000万円でサーキット専用モデルとして発売する事がアナウンスされたと同時完売した事が発表されました。

マクラーレンセナGTRは今月からテストマシンがサーキットでの走行テストを始める事もアナウンスされました。

 

セナGTRには 1,000kgのダウンフォースとGT3レーシング・サスペンション搭載

今月からテストが始まるセナGTRは4.0リッターV8ツインターボエンジンを搭載し25PSアップの825PS、トルクはそのままの800Nm
ピレリと共同開発したレーシングスリックタイヤとマクラーレン650S GT3プログラムで生かされたサスペンションシステムをセナGTRに流用し
ダウンフォース性能は800kgから1000kgへと大幅に向上しています。
今回公開されたデザインスケッチから量産版へと作られますが、おそらくジュネーブモーターショー2018で公開されてセナGTRコンセプトとそんなに変わらないデザインになると思われます。

 

セナGTRの最終仕様や納車時期

  • セナGTRは世界限定75台で1台1億6000万円。
  • 75台全て左ハンドル仕様で右ハンドル車は無し。
  • 3月上旬に開催されたジュネーブモーターショー2018でマクラーレンセナGTRコンセプトを発表後、同月中に予定していた最大75台分のオーダーを抱え完売。
  • セナGTRは公道モデルで世界限定500台のマクラーレンセナ生産終了予定の2019年9月以降から生産が始まります。

セナGTRの最終使用はまだ決まっていませんが、1198kgのセナよりも更に軽くなる予定です。
上記にも書きましたが4.0リッターV8ツインターボエンジンは825PS/800Nmまでスペックが上がり、公道ははしれませんが価格も2億円以上になる事が確実です。
おそらくセナGTRもP1GTRと同じく殆どが公道仕様に改造されそうです。

McLaren Senna GTR moves closer to production with confirmation of technical specification
1,000kg of downforce; 825PS and 800Nm from twin-turbocharged, 4.0-litre V8 engine
Suspension derived from McLaren GT3 race programme and Pirelli slick race tyres confirm GTR’s track-only status
Dynamic prototypes begin running this month as development programme accelerates
Production capped at 75 examples, each priced at £1.1 million plus taxes and all sold
The McLaren Senna GTR, a track-only hypercar that debuted in concept form at the Geneva International Motor Show in March 2018 and sold-out in the same month, begins dynamic testing this month with highlights of its technical specification newly confirmed – not least that it will generate 1000kg of downforce and have race-bred suspension developed from the system used in McLaren’s GT3 programme.

The Senna GTR is an even more extreme version of the road-legal McLaren Senna currently being built at the McLaren Production Centre in Woking, Surrey, UK. McLaren tested demand for the track-only, left-hand-drive only car on its introduction at Geneva, saying that up to 75 would be produced. Many more expressions of interest were received, but the company has confirmed that only 75 will be available, all of which are already allocated. Deliveries are expected to begin from September 2019 when production of the road-legal McLaren Senna is complete.

The development prototypes that begin testing this month will initially use modified Senna road car bodywork. The final Senna GTR shape – shown in simple form in a new design sketch – will be based around a chassis with wider track front and rear and centre-lock wheels. The carbon fibre body has new, wider fenders, a larger front splitter and rear diffuser and repositioned active rear wing; these last two elements combining to improve aero-efficiency by ‘coupling’ the wing to the airflow from the diffuser, enabling greater – and more accessible – downforce at lower speeds. Optimised aerodynamic performance in yaw improves cornering stability, while reduction in pitch sensitivity leads to even greater braking stability.

The lightweight but incredibly strong carbon fibre McLaren Monocage at the heart of each McLaren Senna GTR epitomises McLaren’s approach to weight reduction, a philosophy which is taken even further with the new GTR. A pared-back interior sees all airbags removed, as well as the infotainment central screen and folding driver display found in the road car, while a new, race-style steering wheel with integrated gearshift controls replaces the road-legal component. Air-conditioning is an exception to the rule of absolute minimalism – remaining standard-fit – and a radar-assisted, rear collision avoidance system is also standard.

A final vehicle weight is still to be declared, but the GTR will weigh less than the road-going Senna. In combination with the 825PS output of the 4.0-litre twin-turbocharged V8 engine – an increase of 25PS over the road-legal Senna – this will see the power-to-weight ratio comfortably exceed that of the road car. Together with torque of up to 800Nm, the result will be astonishing levels of response and performance.

The Senna GTR retains the active aerodynamics of the road-legal car – an advantage that would not be permissible in a homologated race car – which is a major enabler in generating the 1,000kg of downforce. The car has conventional double wishbone suspension, with the geometry, springs, dampers and anti-roll bars having been developed from the system engineered for McLaren’s GT3 customer racing programme. Pirelli slick race tyres maximise dynamic performance and the braking system – introduced in the Senna road car and also race-derived – is projected to deliver 20% greater maximum deceleration, with resulting forces in excess of 3g.
