Introduction

BMW knows a thing or two about roadsters and this improved second generation Z4 proved to be one of its best. It may not be the sharpest car in its class from this era to drive, but on the right day, in the right mood on the right road, you may not care, providing you’re a fan of metal-folding roofs. The engines are efficient and willing, the looks are still stunning and the feeling you get behind the wheel still makes you feel twenty years younger.

History

Thinking of a used BMW Z4? We’d point you to the MK2 model – and in particular to the facelifted post-2013 version we’re going to look at here. Back at its original launch in 2009, the Munich maker set itself quite a challenge with this second generation version of its well-regarded roadster. After all, the company’s marketing stance as builder of ‘the ultimate driving machine’ seemed unlikely to be underlined by equipping its affordable roadster for the first time with a heavy folding metal roof.

Yet that’s exactly what we got in a car that in its segment sits somewhere between the elegant cruiser that is Mercedes’ SLK and the sporting appeal of a Porsche Boxster. In this facelifted post-2013 form, it became smarter, faster and more efficient, plus there was a lower-powered entry-level sDrive 18i variant to make it slightly more affordable.

That metal-folding roof tells you a lot about BMW’s target market for this model. If it had been gunning primarily for Boxster buyers, then the Bavarians might have been able to resist the fashionable demand for automotive metal tops that flip down like Swiss army knives. As it was, they felt that the Z4 simply had to have one to properly compete. And as usual, their design team did the best possible job with the tools available. By early 2013 though, newer rivals were stealing the limelight in the roadster sector, hence the introduction of this updated model. It sold until early 2017.

What To Look For

The overwhelming majority of Z4 buyers in our ownership survey seemed to be extremely happy with their cars. However, inevitably, there were a few issues. One buyer complained of a faulty rear diff, a faulty dual mass flywheel and noisy hydraulic lifters. Another found that a broken roof bracket prevented roof operation. And yet another had initial problems with paint finish and various rattles. There were also scattered reports of minor electrical faults. Look out for all these things on your test drive.

Like all modern BMWs, rather than specifying preselected service intervals, the car’s on-board diagnostics indicate when a service is due. It’s therefore important to discover when the last service took place and ask to see documentary evidence of this. Make sure the folding hard top mechanism functions exactly as it should and don't be afraid to be utterly pedantic when running through all of the electrical functions. Check the alloy wheels for kerbing damage and make sure the alarm and immobiliser system are functioning properly. Some owners will have specified their Z4s to the nines from BMW’s options list and will want to claw back what they’ve spent. Don’t entertain any of it.

On the Road

This may be a fashionable roadster but it isn’t a car for ladies who lunch. Slip into the low-slung seat and drop the roof and your eyes are virtually on a level with the long, vented bonnet. It certainly feels like the real deal, especially if you’ve a growly six cylinder engine plumbed in up-front.

The chances are though, that you won’t have. Sporting BMWs may have been inseparably associated with six cylinder engines down the years but most of the powerplants on offer in this improved MK2 model Z4 line-up squirt fuel into the quartet of cylinders boasted by a TwinPower Turbo 2.0-litre unit that was offered in three states of tune. The 184bhp sDrive 20i and 245bhp sDrive 28i variants were carried over from the original version of this MK2 model, but in an attempt to snare customers who might otherwise have to settle for cheaper segment rivals like the Mazda MX-5 or the MINI Roadster, BMW introduced a more affordable Z4 starter-variant for this facelifted design, in the form of the 156bhp sDrive 18i.

If at this point, you’re expecting us to suggest that less is more, then we’re afraid you’re going to be disappointed. When spec changes are taken into account, the sDrive 18i will save you very little over the sDrive 20i that 80% of Z4 customers choose, it’s no more frugal to run, there’s less pulling power on offer and its 7.9s 0-62mph sprint time is a second slower. Arguably the sweet spot in the range though, is occupied by the ultimate four cylinder model, the sDrive 28i, which fires you past the 62mph benchmark in 5.7s on the way to a top speed that has to be reined in at 155mph. The two 3.0-litre in-line twin turbo six cylinder models are similarly restricted, the 306bhp sDrive 35i and the 340bhp sDrive 35is, respectively able to demolish the 0-62mph sprint in 5.2s and 4.8s. There was never a diesel option.

If you’ve found a Z4 whose original owner paid extra for the Adaptive M Sport Suspension set-up, the Drive Performance Control settings can also alter the suspension settings – and therefore the ride comfort. If you’ve got this option, then you’ll find that an extra ‘Sport +’ setting is added to the system which lowers the car by 10mm, firming things up still further for racetrack use and offering 10% more driver leeway before the stability control cuts in.

Overall

BMW has been building roadsters for over 80 years – and that showed with this improved second generation Z4. It was model that matured extremely well, slowly and methodically developing into an all-rounder that's now tough to beat as a used buy if you’re looking for a car of this kind from this era. In fact, we can’t help feeling that this is probably the ideal car of its kind for most potential buyers. True, it isn’t the driver’s machine that, say, a Porsche Boxster can be but it gets close enough for many likely customers to start prioritising the lower pricing and security-minded metal folding roof that come with this BMW.

What it all means is that though the Z4 might not be the first car you look at when choosing a sports roadster, look at it you must. It's just too good not to.
