##BMW 5 Touring--left##WITH a power output of 193bhp at 4000rpm and peak torque of 302lb ft from just 1750rpm, the 530d claims its place as one of the most powerful production diesel cars in the world. Such figures enable the 530d SE Touring to deliver the seemingly impossible: high performance, class-busting economy and industry-leading exhaust emissions, questioning – even ridiculing – the Government's wisdom of the new graduated Vehicle Excise Duty aimed at smaller, supposedly 'greener', cars. In all but badging, the 530d SE Touring – available in SE trim only – looks identical to its petrol-engined stablemates, but it sits between the 525d Touring range and the 530i SE Touring petrol models in terms of pricing at £31,400 for the manual and £32,620 for the automatic. The firmer-sprung 530d Sport starts at £33,905. That's competitive with the Mercedes E320 CDi Elegance (auto only) at £30,980.
