The speed of light

摘要

It's been a long time coming but Jaguar is back in the sports car market again. The formula is a traditional one - front engine, rear drive- but the aluminium body engineering is benchmark, The all-alloy structure contributes to kerb weights as low as 1,597kg, enabling the entry-level 250kW/450Nm V6 model to accelerate to 100km/h in 5,3s. Structural adhesives and some 2,500 rivets join together the body's 141 pressings, 18 castings and 24 extrusions - there are no welds, The entire assembly weighs 261kg: achieving that took 370TB of CAE work.
