The P400 is the more powerful and more expensive of the two petrol engines offered in the new 2021 Land Rover Defender line-up, based around an all new 3.0 litre 6 cylinder petrol engine that the manufacturer has just developed. It has as its name suggests 400 horsepower which is perfect for those using the car in its natural habitat off road, pulling trailers, climbing mountains etc. as it's got a load more torque than the smaller P300 engine with a 0-60 time of just 6.4 seconds. The P400 is currently only available to order in the very top end X specification with its extra dedicated off road tech, which does mean that it's on the prices side, with prices approaching £80,000 depending on options - you have to be putting the car to some serious use to justify that price tag!
