The BMW 5 Series offers a bit more space- it is a luxurious cruiser. There is a lot of legroom in that back-seats and a good amount of headroom as well. The front seats are similarly roomy and easily comfortable. This car, compared to the old model is more stretched and more practical with a 530-litre boot and a range of storage spaces added.
Meanwhile, the 5 Series runs with a smaller range of diesel and petrol engines; the most well-known being the 190hp 2.0-litre diesel. Despite having to transport a heavier car- the engine whose power is similar to the 3 series 2-litre diesel engine- it is just as fast if not a bit more economical. This line-up has a plug-in hybrid engine badged 530ie Performance that can return 142mpg and emissions of 46g/CO2. Gearboxes are the same as 3 series.
While, the 5 Series rivals on most performance measures- the rear-wheel drive is lighter and has a more sophisticated suspension system- powered with equally responsive engines. It is unrivalled in its class.
