A new 2.0-litre turbocharged petrol engine joins the refreshed BMW Z4 line-up

A new entry-level sDrive18i has joined the BMW Z4 line-up as part of a series of mid-life changes to the roadster. The car has made its first public outing this afternoon at the Detroit motor show.

Power for the model comes from a turbocharged 2.0-litre engine producing 154bhp and 177lb ft. That is enough to propel the six-speed manual sDrive18i from 0-62mph in 7.9sec and on to 137mph. Combined fuel economy is rated at 41.5mpg, with CO2 emissions of 159g/km.

An optional eight-speed automatic is also offered.

The engines in the other Z4 models - sDrive20i, sDrive28i, sDrive35i and sDrive35is - continue unchanged.

Cosmetically, the changes to the facelifted roadster are minor, the revised LED headlights being the stand-out change. New alloy wheel options are offered, while there are minor exterior trim detailing changes.

Other changes include the option of a new Design Pure Traction styling pack, which adds contrasting black and orange trim to the cabin. The interior also features new gloss black trim for the air vent and iDrive surrounds as standard. Leather trim is also standard for the sDrive28i models and above, with a Fineline Anthracite wood finish available as an option.

The M Sport package - comprising bespoke suspension settings, alloy wheels and exterior and interior trim - is again offered, with a more focused version of this pack available on the sDrive35is range-topper.

The revised Z4 is due to reach the UK in April.

Our Verdict

BMW Z4
The BMW Z4 has more comfort and added practicality, but has it gone soft?

The BMW Z4 is a fine-looking two-seat roadster with indifferent driving dynamics

154/177 from a 2 litre turbo?  Shurely shome mishtake?

bmw has a habit of selling detuned engines, that is probably the 18i

I agree with the detuning it allows them to retain the classic numbering but with less engines  in various states of tune.

The only thing that seems odd here is why bother adding a turbo it when the standard 2.0 litre is round the 185 horses? You may as well detune without the turbo.

What is a Turbo.  Merely a method of making Fuel / Air ratios in the combustion chamber more efficient.  Lowering Carbon emissions and getting more bang from your precious Buck.

The 1.6-litre twin turbocharged engine in the 114i develops a paultry 100bhp, so I wouldn't be at all surprised if BMW is serving up some gutless outputs from a 2.0-litre turbo as well.

Oh, and as for the facelift, it still looks like it did in 2009 or whenever it came out.

Let's hope it's matched by an "entry-level" price.

You would have thought it would have been a better option looking at those figures to slot the 1.6 twin scroll turbo in from the Mini. Having more tq/power and most likely better economy.

I don't know I wouldn't be surprised if this achieves real world economy much closer to the claimed mpg figures than most other cars. It'll probably produce it's best at low to medium revs, which if I'm being honest will probably suit the majority of buyers, it's not as if most drivers of this kind of vehicle are serious driving enthusiasts.

Why do BMW not fit their 2.0 diesel to this car?

It would increse sales and probably be the biggest selling version throughout Europe.

I know it was a big improvement on the looks of the original Z4 (and let's face it, that wasn't hard), but the current Z4 doesn't seem to be ageing that well.  I was hoping for a more substantial facelift after reading the headline.

Those angles and lines, both internally and externally, are all over the place.  It's really really close to being a great-looking car, but let down by the surface treatments - which could be said about pretty much any BMW since Bangle started.  His successors are gradually finding their way back to reality, but they're not quite there yet.

    The Citroen C3 Aircross has got funky looks and a charming interior, but it's another small SUV, and another dynamic miss. Numb steering is just one thing keeping it from class best
