Radical SR1

A fabricante inglesa Radical Sportscars lançou seu novo modelo de entrada, o SR1. De olho nos pilotos que querem participar de track days ou de clubes de automobilismo, o leve chassi é inspirado no SR9 LMP2.

O motor que empurra o conjunto é um RPE-Suzuki 1.3 de quatro cilindros, o mesmo usado em outros modelos da Radical. O propulsor gera 210 CV de potência e 17,97 kgfm de torque a 10.500 RPM. A transmissão é sequencial de seis marchas e o diferencial de deslizamento limitado é um Quaife ATB.

O carro acelera de zero a 100 km/h em 3,6 segundos e a velocidade máxima é de 222 km/h. Os discos de freio são ventilados e medem 240 mm de diâmetro com pinças de quatro pistões. A célula de segurança é certificada pela FIA. O veículo possui partes deformáveis em colisões, cintos de segurança especiais para competição e um sistema de extinção de incêndio. Como opcionais, há pneus da Dunlop específicos para os carros da Radical Sportscars, além de pneus para pista molhada e para o trânsito nas ruas.

"Ao longo da última década, a linha SR introduziu e inspirou uma nova geração de entusiastas, e o SR1 estende o desenvolvimento da engenharia a um público ainda maior. O carro oferece muita diversão e performance a um preço acessível para pilotos de diferentes habilidades e idades", disse Phil Abbott, co-fundador da Radical Sportscars. O Radical SR1 possui um preço-base de 29.850 libras esterlinas.

RADICAL ANNOUNCES THE SR1, A NEW AND THRILLING EDITION TO ITS GLOBAL RANGE OF LIGHTWEIGHT SPORTSCARS
The entry-level sportscar with real racing credentials

Designed for enthusiasts looking to take their circuit driving to the next level with a focused sports-racing car, the SR1 concept wraps up the Radical ownership experience into one easy package with a comprehensive standard specification that is ideal for trackdays and club motorsport, including circuit racing, hillclimbs and sprints.

The SR1's LMP-inspired styling is no accident. Developed by the same team that created Radical's SR9 LMP2 racecar, the SR1 mirrors current prototype design, while the two-seater cockpit is ideal for professional driving tuition, or even entertaining business partners and friends. Powered by the exceptionally reliable, 210bhp RPE-Suzuki four-cylinder engine - used to great effect in a wide range of Radical's existing products - the SR1 features a six-speed sequential gearbox as standard, with a Quaife ATB differential ensuring very high levels of grip and control.

Braking is provided by 240mm, 30-vane ventilated discs with four-pot calipers that generate exceptional stopping power. Occupants are protected by a comprehensive safety cell and deformable crash structure tested to FIA standards, racing-specification harnesses and an integral fire extinguisher system. Latest-generation sportscar aerodynamics mean that the SR1 sticks to the track like only a Radical can, with grip limits far beyond the realms of its market rivals thanks to Radical-specific Dunlop slick, wet and road tyre options.

"Over the last decade, the SR range has introduced and inspired a new generation of racing and track driving enthusiasts, and the SR1 extends that engineering development out to a wider audience," said Radical co-founder Phil Abbott. "The SR1 is brilliant fun to drive and the performance is readily accessible for drivers of all abilities and ages. We're all really excited about the SR1 and I'm certain that it will be a huge success. You only have to take a brief test drive to discover just how good the car is!"

Unbeatable performance-for-pound ratio
The Radical SR1 retails at £29,850+VAT; in this price range, nothing touches it for speed and trackday ability. Revving higher, braking later and cornering harder than the opposition, the SR1 humbles GT and supercars with six-figure price tags.
