The R’s engine gets a new head, uprated pistons and conrods, and higher-pressure injectors. The turbo produces more boost, and there’s a new intercooler to deal with the extra heat.
Combined, these changes give the new engine 261bhp and 258lb ft — and all of the torque is available from 2500rpm through to 5000rpm, one of the advantages of using direct injection on a petrol engine. A six-speed manual transmission is standard, while a six-speed, twin-clutch DSG is optional. The R turns in a 0-62mph time of 6.4 sec
