Representative Example - Personal Contract Purchase: Cash Price £10,000.00, Deposit £1500.00, borrowing £8,500.00 over 4 years at 7.4% Representative APR (fixed). 47 monthly payments of £132.04 followed by a final payment of £4127.50. Total cost of credit £1833.38. Total amount payable £11,833.38. Based on 8,000 miles per annum. Excess mileage charges apply if exceeded. Finance subject to status 18+ only.

Industry safety body, Euro NCAP, has yet to test the i4, but based on BMW’s excellent safety scores for its other models, we think it should achieve a top five-star rating. The 4 Series Coupe model underwent crash test examination in 2019 and was given a 97 per cent score for adult occupant protection, while BMW’s all-electric iX SUV has also secured first-class safety status.

Standard safety kit for the i4 is excellent and includes BMW’s Driving Assistant package of camera and radar-based driver assistance systems that help prevent a potential collision. The optional Tech Plus pack offers an opportunity to upgrade to the Driving Assistant Professional system, which provides further semi-autonomous safety functions, along with a head-up display.

BMW hasn’t fared too well over recent years in our annual Driver Power customer satisfaction surveys, although it moved up to 16th place (out of 29 brands) in 2022 - up from 21st spot in 2021. For an automaker that prides itself on producing the ‘Ultimate driving machines’, it will want to see more of its models higher up the order in the Best cars to own poll - the 3 Series saloon was the best-performer in 2022, achieving 32nd place on a 75-car list.

Warranty

BMW offers a three-year, unlimited mileage warranty, which includes free roadside assistance, while the high voltage battery is covered for eight years or 100,000 miles - whichever comes first.

Servicing

BMW offers an individual three-year service plan for its ‘i’ electric range - owners pay £15 per month over three years to cover all scheduled maintenance.
