El Radical SR1 cruza la línea entre el juguete de pista intimidante y la herramienta de aprendizaje accesible

1 DE NOVIEMBRE DE 2021
2021-Radical-SR1-_2.webp


Aprender a domesticar un coche de carreras no es tarea fácil. Son muy caras, el tiempo en pista es difícil de conseguir y todo es un poco peligroso. Pero si está buscando aprender, hay pocos lugares mejores para comenzar que en un Radical SR1.

Construido exclusivamente para la pista, el SR1 no hace concesiones a la legalidad de la carretera ni a las comodidades. Eso significa que a pesar de estar propulsado por un pequeño motor de 1.3 litros que genera solo 182 hp (184 PS / 135 kW), o menos que un Ford Fiesta ST , sigue siendo una bestia. Con una inclinación de la balanza de solo 490 kg (1.080 libras), tiene una relación potencia / peso de 371 hp por tonelada.

Eso es bueno por un par de razones, dice Drew Stearne de Carfection. Gracias a su bajo peso, su rendimiento orientado a la pista y su impresionante carga aerodinámica, es un monstruo absoluto en un circuito como Silverstone .



“Inmediatamente, la velocidad a la que esta cosa podía tomar una curva me impactó”, dice Stearne. “Mi cabeza estaba clavada en el respaldo de mi asiento y cualquier esfuerzo por inclinarme hacia adelante, aunque fuera un poco, fue en vano. Embistiendo en una esquina rápida y ciega como Copse, no podía creer cuánta velocidad [mi instructor] Bobby podía llevar sin siquiera parpadear ".

Dada la rueda, dice que se sintió intimidado, pero no tanto como para no intentarlo. Y con la telemática y las imágenes de conducción para ayudarlo a enseñarle lo que estaba sucediendo de esquina a esquina, dijo que la curva de aprendizaje se aplanó de inmediato, lo que lo ayudó a hacer avances más grandes de lo que podría haber imaginado. El Radical SR1 y el programa que lo rodea podría ser la mejor manera de ser más rápido en una pista.

“Este automóvil fue diseñado exactamente para personas como yo”, dijo Stearne. "Lo suficientemente desafiante como para hacer de cada sesión una experiencia de aprendizaje y lo suficientemente atrevido como para asegurarse de que los hábitos y las malas decisiones le den un golpe en la muñeca, pero sin hacer que sienta que el automóvil es demasiado para manejar".




The Radical SR1 Walks The Line Between Intimidating Track Toy And Accessible Learning Tool
NOVEMBER 1, 2021

Learning how to tame a racing car is not an easy task. They are very expensive, track time is hard to come by, and it’s all a little bit dangerous. But if you’re looking to learn, there are few better places to start than in a Radical SR1.

Built exclusively for the track, the SR1 makes no concessions to road legality or creature comforts. That means that despite being powered by a tiny 1.3-liter engine that makes just 182 hp (184 PS/135 kW), or less than a Ford Fiesta ST, it’s still a beast. Tipping the scales at just 490 kg (1,080 lbs), it has a power-to-weight ratio of 371 hp per tonne.

That’s good for a couple of reasons, says Carfection’s Drew Stearne. Thanks to its low weight, its track-oriented performance, and impressive downforce, it’s an absolute monster on a circuit like Silverstone.

“Immediately, the speed at which this thing could corner blew me away,” says Stearne. “My head was pinned to the back of my seat and any effort to lean forward even slightly was in vain. Barreling into a fast, blind corner like Copse, I couldn’t believe how much speed [my instructor] Bobby could carry through without even blinking.”

Given the wheel, he says he was intimidated, but not so much that he wouldn’t try. And with telematics and driving footage to help teach him what was happening corner to corner, he said the learning curve was flattened right out, helping him make bigger strides than he could have imagined. The Radical SR1 and the program surrounding it might be the best way to become faster around a track.

“This car was designed exactly for people like me,” said Stearne. “Challenging enough to make every session a learning experience and edgy enough to make sure that habits and poor decisions give you a slap on the wrist, but without ever making you feel like the car was too much to handle.”
