BMW 5 Series vs Mercedes E Can the new Mk7 BMW 5 Series regain the class crown from Mercedes and Jaguar? The pace is hot at the top of the executive saloon sector.
BMW knows it, which is why it's gone to town with the development of its all new, seventh generation 5 Series.A glut of new premium saloons arrived last year, including the Mercedes E Class, which hit the market with a range of advanced technology, autonomous driver aids, more space than ever and a slick cabin. It's our current executive champion, and the car BMW will have to beat.However, the 5 Series has traditionally offered a dynamic edge over its rivals, too, so while it will face some stiff competition from the E Class on everyday issues such as versatility, safety and tech, if it wants to reign as the best handling saloon in the sector, it will have to outpace the agile Jaguar XF.Here we test the three cars at the centre of the class, all in efficient 2.0 litre diesel form and sportier trim levels, to determine which is the greatest all rounder in what will undoubtedly be one of the hardest fought and most important road tests of 2017.The executive saloon sector is fiercely competitive, with cars such as the VolvoS90 and Mercedes E Class changing the game recently. It's the latter car this new 5 Series will have to beat. BMW now offers it with four wheel drivefor the first time on right hand drive models, oakley sonnenbrille and here we test the 41,025 520d xDrive M Sport.BMW has fitted the 520d with the 187bhp 2.0 litre turbodiesel engine that features across much of its range. On test it offered truly impressive performance, sprinting from 0 60mph in 7.4 seconds and delivering pace to rival out and out sports cars such as the Mazda MX 5 and Toyota GT86.Its speed off the line was helped by its xDrive four wheel drive system, which offers great traction. However, giving away some power to the Mercedes, it was one tenth slower over the benchmark sprint.With 400Nm of torque, it was on par with the lighter, 430Nm XF for in gear acceleration, while its superior traction and sharper shifting gearbox meant it was faster than the Jaguar through the gears.The transmission locks up oakley frames only quicker so the BMW gets off the line better than either of its rivals, and the engine is also the most refined of the three.This refinement extends to the ride. While you do feel a few pattering motions over the worst surfaces, riding on optional 19 inch wheels (with 18 inch rims as standard) bumps don't send a quiver through the chassis like in the E Class. In Comfort the 5 Series works with the road rather than reacting to it.In Sport mode, the damping doesn't feel too much firmer until you enter a corner. Then you notice the tauter body control and greater resistance to roll, with the 5 Series staying fairly flat. Our car was fitted with the 985 Variable Damper Control, which is well worth the extra outlay. The steering is nicely weighted and the rate of response judged just so, meaning the BMW rarely loses its composed feel.Testers' notes: "The 2,000 xDrive system adds security in slippery conditions, but the two wheel drive version is more efficient, matching its rivals' Benefit in Kind rates of 22 per cent."The Mercedes E Class is our current class favourite, thanks to its blend of upmarket appeal and wallet friendly running costs. It comes in just two trim levels and features a nine speed auto gearbox. Here, we test the sporty AMG Line version in popular E 220 d guise, which costs 39,170.With 191bhp, the Mercedes' 2.0 litre diesel is fractionally the most powerful engine here, but its 400Nm torque output trails the Jaguar's by 30Nm. Still, despite similar on paper figures, the E Class held a narrow oakley online shop advantage in the 0 60mph sprint; its time of 7.3 seconds was a tenth faster than the 520d's.The tables were turned during our in gear assessments, where the E 220 d was consistently slower than both its competitors in this test although admittedly the margins were small. The Mercedes is refined, too. Work the four cylinder hard and you still hear a diesel grumble from under the bonnet, but it's not as gruff as the Jaguar's.On the motorway the nine speed auto makes for low cruising revs of just 1,300rpm, but the trade off is constant downchanges after even light throttle applications. On the plus side, the slippery shape also means there's virtually no wind noise in the cabin.Our car was fitted with the standard coil springs and adaptive damper suspension, which does a better job of soaking up bumps than the firmer Jaguar, but trails the BMW for ultimate comfort. While it deals with big bumps well, broken tarmac and potholes send the occasional shake and shudder through the floor of the cabin.The E Class isn't as agile as its rivals here, and its quick steering lacks feedback, but you can't fault its grip and composure. Sport+ mode sharpens the throttle and adds weight to the steering, but the car is at its best while cruising in its normal setting.Testers' notes: "There are lots of personalisation options, including alloy wheels, paint finishes and trim although the 645 black and pinstripe panels on our car won't be to all tastes."For a brief period, Jaguar's XF reigned supreme at the where to buy oakley sunglasses cheap top of the executive saloon sector. Then the E Class came along and knocked it off its perch last year. So can it still hold its own, or have Jaguar's rivals moved the game on and out of the XF's reach? To find out, we test the 36,850 R Sport 2.0d auto, although our pictures show a Portfolio model.Given the poor conditions during our performance tests, it was no surprise that the rear drive Jag couldn't match the four wheel drive 5 Series' 0 60mph time, taking 9.3 seconds. However, its in gear performance was on par due to the XF's superior 430Nm of torque and lower 1,595kg kerbweight.The eight speed Jaguar was actually faster than the more powerful BMW from 50 to 70mph in top, taking 15 seconds exactly, while there were only a few tenths' difference in the other gears.However, when you use the transmission you'll find it isn't as slick as the BMW's eight speed auto. The two cars share the same ZF sourced gearbox, with bespoke programming for each model.The Jaguar doesn't pull away quite as urgently as the BMW and feels more lethargic as a result. While its changes are nicely managed, in manual mode they're not as snappy or as smooth as in the 5 Series.It's a similar story when it comes to the ride. Our test car was fitted with the 1,020 optional Adaptive Dynamics system that alters parameters such as suspension damping and throttle response.Even in Normal mode it can't match the 5 Series or E Class for comfort, with more vertical body movement over rougher roads. In Sport it's firmer still, but at least the Jaguar feels agile.
Its steering is very fast, which can give it a nervous feel at first. The suspension sometimes struggles to keep up with the speed of direction changes and control the car's mass, but it's direct and, once you get used to it, feels alert. However, it does have a tendency to follow cambers and ruts in the road.
