Lamborghini Aventador J Roadster revealed officially

Lamborghini Aventador J Roadster After the leak of the Lamborghini Aventador J over the weekend, tonight we get the official reveal of Lamborghini’s stripped-out Aventador Roadster When we ran leaked photos of the Lamborghini Aventador J Roadster at the weekend we said it threatened to steal a bit of Ferrari’s limelight at the Geneva Motor Show – and it will. The Aventador J  Roadster is Aventador to the max, with all fripperies – including the windscreen and roof sacrificed in the pursuit of low weight and extreme performance. Lamborghini say the Aventador J is a four-wheeled sport-bike, and they’re not wrong.

We took it to the streets to see how Nissan's scattershot small car strategy – which sees a range of four models occupying a similar space physically and fiscally – plays out.
