How does this differ from the Grandland entry?
Our history records the model under both designations. Each group covers different units, so it is worth checking both.
What is the 1.2 THP PureTech?
It is PSA's turbocharged three-cylinder petrol, which responds well to a measured map given its small displacement.
Is it related to the Peugeot 3008?
Yes, it shares platform and engines within the same group. Our experience with the PSA units applies directly.
