BMW 5 Series vs Audi A6

When choosing a company car, Benefit In Kind is king. Models looking to become a common sight in the corporate car park need competitive tax bills, and that means low emissions and reasonable prices.

Yet there’s more to executive car success than cost-cutting: any class contender also needs to be desirable, good to drive and well equipped – and this is where the Audi A6 scores so highly.

The stylish saloon is beautifully built, spacious and features plenty of standard kit. What’s more, it has excellent straight-line speed and a very composed chassis, while it’s as refined as any other car in the class.

Yet the 520d ED isn’t short of premium appeal and its rear-wheel-drive chassis delivers even more driver thrills. It also boasts a roomy interior, a decent haul of kit and is as solidly built as its rival. The only downside is the blunted performance that results from the car’s various eco-friendly tweaks.

But for most drivers, this will be a small price to pay for the significant Benefit In Kind savings on offer. Impressively low CO2 emissions mean the BMW costs company users less to tax than a smaller Audi A4, let alone the A6. Factor in its better fuel economy and the 5 Series takes a comfortable victory in this encounter.

Winner
BMW 520d ED ★★★★★
As an ultra-efficient executive saloon, the 520d EfficientDynamics is a tough act to beat. It shares the imposing looks, classy cabin and sharp driving dynamics of the standard 520d, while adding impressively low running costs. It’s a superb package that’s only let down by slightly underwhelming performance.

2nd
Audi A6 2.0 TDI SE ★★★★★
Make no mistake, the Audi A6 is still a hugely capable and desirable executive car. It’s neatly styled, features a class-leading cabin and comes brimming with equipment as standard. What’s more, it’s refined and good to drive. But if it wants to regain its place at the top of the class, the A6 needs to deliver lower CO2 emissions and better fuel economy.
