Mercedes E-Class vs Jaguar XF vs Audi A6

Despite the ever increasing popularity of upmarket SUVs and crossovers, sales of premium executive saloons are still going strong. 

So the arrival of an all-new Mercedes E-Class to the market is big news. While its predecessor was solidly built, it lacked that wow factor. However, with its hi-tech kit and styling cues from the brand’s S-Class limousine, this latest car promises to set a new class benchmark. 

Under the sleek lines are totally overhauled engines, which, in combination with the slippery aerodynamics and nine-speed automatic gearbox, make the Mercedes one of the most efficient models in the class. At launch, there’s a choice of SE and sporty AMG Line trim levels, and it’s the latter we test here in £38,430 220d guise. 

But before Mercedes can start uncorking the champagne, the E-Class has to see off a pair of extremely talented rivals in the form of the Jaguar XF and Audi A6.

The Jaguar is our current class champ, thanks to its desirable blend of handsome styling, cosseting interior, composed driving dynamics and low running costs. 

The A6 is getting on a bit, but it scooped Executive Car honours at our 2015 New Car Awards, and blends an unrivalled image with impeccable quality. So which of our captains of industry will come out on top?

Head to head

Technology

34

These cars are packed with hi-tech additions, but the E-Class leads the way for gadgets. A highlight is the £1,695 Driving Assistance Plus, which includes the clever Drive Pilot. This neat piece of kit combines with the adaptive cruise to allow virtually hands-free progress on the motorway. It will even brake and accelerate the car in traffic.

Badge appeal

34

Our contenders ooze upmarket appeal, so it’s no surprise they’re closely matched on residuals. The Mercedes leads the way, retaining 45.7 per cent of its new value after three years according to our experts, while the A6 brings up the rear on 43.6 per cent. All three are fairly good.

Emissions

The Audi emits the least CO2 here, at 110g/km. However, if you’re looking to lower your Benefit in Kind bills, then the Mercedes E 220d in SE guise is the best bet. It emits just 102g/km, dropping it into the 20 per cent tax bracket.

Verdict

First place: Mercedes E-Class

34

Mercedes has hit the ground running with the E-Class. The newcomer is more stylish than its predecessor and features an interior that sets new standards for quality and design. Refinement is also top notch, while the S-Class-inspired technology makes it safer and easier to live with. It’s not quite as fun to drive as the XF, but it’s close enough in a class where comfort and composure count.

Second place: Jaguar XF

34

The margins are extremely tight, but the XF tastes defeat for the first time. Sleek looks, agile handling and a generous kit list make the Jag a desirable choice. It’s also a cost-effective company car and offers plenty of space. Yet it can’t match the Mercedes for refinement and cutting-edge kit, while the cabin just falls short in terms of class and quality. 

Third place: Audi A6

34

Third place is no disgrace for the A6. Despite its advancing years, it still looks good, drives well and makes plenty of financial sense for business users. And while the cabin is starting to show its age, there’s no doubting the quality of the finish and materials. However, it lacks the latest tech of its rivals, while the S tronic gearbox isn’t well suited to UK roads.

The BMW is six years old, but it shows no signs of slowing down. Its balanced rear-wheel-drive chassis still sets the handling benchmark, plus the 520d is beautifully built. Its cabin is just a bit cramped and it’s not as efficient as the best.

Lexus GS 300h F Sport

Price: £40,995Engine: 2.5-litre 4cyl/electric, 220bhp

The impeccably finished Lexus goes its own way with an efficient petrol-electric powerplant. It can’t match its rivals here for driver engagement and the F Sport model is expensive, but the GS is loaded with kit and cheap to run for business users.
