Motorists who buy BMW car parts to help keep their auto running as efficiently as possible may be impressed by improvements to the manufacturer’s 730d.

The company has equipped the model with a new powerplant that offers better fuel economy and lower CO2 emissions.

Buyers can expect the latest version of the car to achieve 41.5 mpg on the combined cycle.

In addition to this, CO2 emissions have fallen to 178 g/km – a drop of 7.3 per cent compared to the vehicle’s predecessor.

As a result, owners of the model will qualify for band I road tax, while business users will also see an improvement in their benefit-in-kind rate.

The vehicle is due to arrive in showrooms up and down the UK in September.

Meanwhile, motorists who cannot afford to trade in their current auto right now may find they can keep it running smoothly for many years to come by replacing worn parts with BMW car spares bought online.

Drivers who always replace their worn BMW car parts to make sure their motor is running as efficiently as possible may be impressed by the latest model from the manufacturer.

According to the company, the 316d ES saloon sets a benchmark when it comes to fuel economy and green credentials in the high performance sector.

Due to arrive in UK showrooms in September, the model is capable of achieving 62.8 mpg on the combined cycle.

In addition, it boasts CO2 emissions of 118 g/km, meaning it qualifies for road tax of £35 per year.

Priced at £23,330, the vehicle features a range of standard equipment, including front fog lights, multi-function leather steering wheel and air conditioning.

However, people who cannot afford to shell out for a brand new vehicle at the moment may find they can keep their current auto running smoothly by replacing worn parts.

Motorists may well find they can buy a range of cheap BMW car spares online.

BMW owners "love" their motors, it has been claimed.

Which? made this statement after awarding the company the title of Best Car Manufacturer in its 2009 honours.

Chief executive of the consumer champion Peter Vicary-Smith commented: "BMW drivers seem to love their cars, with 87 per cent in our survey describing themselves as very satisfied with the ownership experience."

He stated the group’s EfficientDynamics technology also means its vehicles are now "incredibly fuel-efficient".

The latest Dow Jones Sustainability Index recently named the manufacturer as the world’s most sustainable auto company.

Mr Vicary-Smith also pointed out the firm’s cars always excel in road tests.

The triumphant company’s UK managing director Tim Abbott expressed delight at winning the award, stating it was particularly gratifying that its customers rate the firm so highly.

Meanwhile, motorists may find by replacing worn BMW car parts, they can keep their pride and joy running smoothly for many years to come.
