#688 hs

The MSO HS is lighter than the standard 675 LT and boasts improved aerodynamics coupled with an updated twin-turbo 3.8-liter V8 engine. It makes 688 hp and 516 lb-ft of peak torque. A revised titanium exhaust system is one of the reasons for the improvement in engine performance. The exhaust features a cross muffler to add more length and thus optimize flow.

The revised exterior features a P1-esque active rear wing. This new spoiler along with the front splitter, dive planes and vents add 220 kg of downforce at 150 mph.

To cut down on weight, McLaren Special Operations offers the MSO HS with Alcantara interior trim and carbon fiber racing seats. That’s straightaway a saving of 18.5 kg. Door-mounted heater controls are now integrated into the infotainment system.

It comes fitted with McLaren’s Track Telemetry package, three on-board cameras, F1-style shift lights and racing harnesses in place of normal seat belts.

The McLaren MSO HS is an exclusive model production of which will be limited to just 25 units. All cars will be built to customer specifications by MSO

Autocar did some digging around and got to know from an insider source that McLaren will build 25 examples of the MSO HS. It apparently won’t enter series production.

The Mclaren MSO HS is a heavily modified version of the 675LT Super Series coupe. It’s 40 kg lighter than the 675LT and is slightly more powerful as well. The 3.8-liter twin-turbo V8 engine in the MSO HS makes 679 hp and features revised aerodynamics. It uses a P1-style active rear wing for additional downforce.

We expect the McLaren MSO HS to be revealed at the Paris Motor Show next month. More details of this special model will available soon. So, keep watching this space.

It is an iteration of the 675 LT but will be made is very limited numbers. Also, McLaren has been very picky about who would get to own the 688 HS. Apparently, only those customers who have been associated with McLaren Special Operations (MSO) before will get the chance to own one of these. Just 25 cars will be built and all of them have already found a buyer.

So, what is the 688 HS. Well, ‘HS’ stands of High Sport and it is based on the 675 LT which means it shares the same 3.8-liter twin-turbo V8 engine as the LT. However, peak power is up by 13 hp and on the outside, the active rear wing has been replaced with a massive fixture that looks it was borrowed from the 650S GT3 race car.

Apart from the spoiler, the McLaren 688 HS also sports a reworked aero on the front which includes additional dive plains and a roof scoop. The bare carbon fiber hood, roof, front splitter and rear diffuser along with the aggressive rear wing give the car a rather sporty look.
