Game-changing 2015 fuel economy rules are forcing vehicle development teams to make high-stakes bets on expensive technologies--bets that will separate the winners from the also-rans.

The new Audi SQ5 – a diesel RS Q5 in all but name – bowed in at Le Mans in June featuring the 3.0 litre twin turbo diesel V6 with 479lb/ft of torque, 309bhp and a very un-SUV 0-62mph of 5.1 seconds.
