Speedster 3-Eleven received a special version with the index 430, which became the fastest road model in the history of the British brand. Outside of the usual 3-Eleven, the 430 is distinguished by the presence of a revised aerodynamic body kit that includes a front splitter, a fixed rear wing, and a diffuser. At maximum speed, this body kit provides 265 kg of clamping force (+ 44). The modification is based on a light chassis made of extruded aluminum, while the body panels of the speedster are made of carbon fiber. As a result, the mass of the car is only 920 kg. The novelty is driven by a 3.5-liter compressor “six” with a mechanical supercharger. Combined with the six-speed mechanics, this motor develops 436 hp. and 440 Nm. From a place to a hundred, the 3-Eleven 430 can accelerate in 3.2 seconds (maximum speed 290 km/h), which is 0.2 seconds faster than the 416-strong standard model. In the list of equipment of the fastest road, there is an anti-slip system with six operating modes, adjustable front and rear stabilizers, a self-locking Torsen differential, adjustable Ohlins dampers and four-piston brake calipers.
