Lamborghini Aventador J at 2012 Geneva motor show

There maybe other Italian sports car manufacturers looking to hog the limelight at the 2012 Geneva motor show (and Ferrari and its 730bhp F12 is one of them) but Lamborghini will vie for attention with the Aventador J. A two-seat, open top speedster based on the Aventador LP700-4, it has some intriguing bits of carbonfibre tech and highly individual design. Named 'J' after the FIA’s Appendix J that governs the tech spec of race cars in certain classes, it’s proper bedroom wall material – but little boys and girls are unlikely to ever see it on the road as it’s a one-off and will go to a lucky owner after its appearance at Geneva.

Economic downturn might hit plans for Porsche small roadster

Porsche's decision on whether to build an entry-level roadster will depend on the global economy, CEO Matthias Mueller said. Mueller said that if the automaker decides to go ahead with the car, sales would begin at the earliest in the third quarter of 2014, but probably later. A decision on production will depend on how the global economic situation pans out, particularly in relation to the auto industry, Mueller said.

Parents 'risking kids' lives' on defective tyres

MORE THAN 30% of parents are ferrying their most precious cargo around on illegal tyres, a new study has found. Road safety charity TyreSafe has reported that one of its members carried out a study at a Shropshire primary school, where almost a third of the cars dropping children off at school were wearing tyres that were either past their wear markers, were incorrectly inflated, had bulges or cuts, or had foreign objects sticking out of them. “The start of the new academic year means that we will be experiencing many more cars on the roads, particularly at peak times of the day,” comments Stuart Jackson, chairman, TyreSafe.
