This is the entry-level diesel engine and, in Ecoflex guise, also the most efficient. Available with a six-speed manual only, it offers CO2 emissions of 91g/km and claimed fuel consumption of 83.1mpg. Even the standatd version manages 97g/km and 76.3mpg. A 0-60mph time of just over 10 seconds means it’s fairly brisk as well as refined. The best choice for business users.
