BMW Z4 vs Lotus Emira

What's the difference?

The Z4 didn’t make me feel like Peirce Brosnan’s 007. It’s way too serious – a proper gritty reboot. Maybe it’s meant for Daniel Craig. Either way, its brave design makes it one of the best-looking BMWs of recent memory, and it’s a tech- and comfort-fest that the Bavarian automaker should be proud of. I just wish it was a smidge more fun behind the wheel.

If this really is the final petrol-powered Lotus sports car then it’s a sad day for fans of the brand and its history. But it’s also worthy of celebration because they have made a car that is genuinely impressive.

It may not be perfect, and it will have to fight hard to lure buyers away from Porsche, BMW and co. but for anyone who enjoys a dynamic, engaging and incredibly fun sports car the Emira should be on your short-list.

Alternatively, if you’ve always dreamed of buying a traditional Lotus sports car and haven’t got around to it until now, this is your last chance so don’t wait too long.

The Z4 is a sight to behold. It’s brave, especially for a BMW, it even betrays the brand’s strongest styling pillars, making its own way with its more horizontal grille design, flat body and curved out rear.

It’s more than that, though. In black, this car looks sinister, brooding. The more you look at it, the more you notice tiny details - the scooped-out sides, or the way the entire rear seems to flick up into the integrated spoiler. I couldn’t get enough of staring at it – it manages to look even better with the roof down.

That’s probably when it hit me. To my eyes, at least, this is the most stunning BMW in years. Sure, the X7 is a sight to behold due to its sheer dimensions and borderline offensive grille, but the Z4 is the opposite. It’s subtle, it hides its details away in its silhouette.

It’s designer, Calvin Luk (an Australian no less), was inspired at least in part by the Z8 – another Brosnan bond car – and you can see the Fisker design reflected in the Z4’s low, flat grille and almost bulbous rear.

Inside, sadly, the Z4’s strong design doesn’t quite play out. There’s no wily Fisker touches here, just a standard set of BMW switchgear. While it all works well, it just dumbs down the Z4’s character.

The big, chunky steering wheel in particular is a let-down. It’s the same wheel that sits in the brand’s X5 SUV, and it feels right there, but not here in a convertible where you’re so close to the ground. A smaller wheel would not only suit this car better, it would make it feel just a smidge more alive. I miss the three-spoke M sport wheel from previous-generation BMW cars.

I do like the dash, which is seemly carved from rhomboid shapes - a theme that rolls into the doors, screens, and vents elegantly. I’m normally not a fan of gloss plastics and chrome touches, but in the Z4 they’re all tastefully applied.

The seats, too, are lovely. I’m not sure about the contrast bright-red leather our car came with, but they’re nice and close to the ground and have excellent trim that you seem to sink into just enough to be comfortable and sporty all at once.

It’s a slick place to be, I just wish it felt less like you were at the helm of an SUV and more like you were driving something that looks this damn good.

As mentioned earlier, the Emira is meant to be a bridge between Lotus’ past and its future - combining elements of its previous sports cars while also laying the visual tone for future models.

The design does a good job of that, because there’s clearly a link to the Exige and Evora of the recent past, but it also takes heavy influence from the limited-run Evija hypercar.

In turn, this new design language will spread out across the all-new electric models, including the Eletre SUV and Emeya sports sedan.

The styling does a good job of making the Emira look and feel like a premium sports car, without the need for any flashy wings or similar. It’s a simple, compact but stylish sports car.

This trend carries over to the cabin, with the more premium finish with the carpets, leather and good quality switchgear, as well as the digital instrument display and 10.2-inch multimedia touchscreen. Gone are the days of a Lotus having a minimalist, exposed aluminium interior with only the bare necessities. This is a proper premium sports car.

The Z4 is a convertible, so it’s naturally compromised on space. As far as convertibles go though, you’ll be hard pressed to find one you can fit more stuff into.

The Z4 is wide - the same width, in fact, as a 5 Series - and this carries into the cabin. There are only two seats, but those seats are wide, and occupants will find themselves with luxurious amounts of airspace for their arms, as well as excellent leather-trimmed and padded surfaces for landing elbows on.

Legroom is also great, as the seats have a surprising amount of rail-travel on them, so that even taller folk won’t struggle to fit their limbs in.

A genuinely impressive characteristic of the Z4 is much head room there it is. Despite its low-slung looks from the outside, the roof towers over my 182cm tall head when I’m inside, so this isn’t one of those convertibles that feels like braking too hard might simply decapitate those above six-foot tall.

In terms of storage areas you get some long but shallow trenches in the doors, a bay with connection ports and a Qi wireless charging pad under the air-conditioning controls, a glovebox (hey, not all convertibles have them) and a trick centre console that houses two deep cupholders inside.

There’s also a netted shelf behind the seats that could fit small bags, and given the length of the cabin, you could even fit laptops and the like behind the seats provided you haven’t used the full extent of the seat’s rearward movement.

The boot is deep, wide and long for a drop-top, and offers a total of 281-litres which is more than some popular hatchbacks. It even offers tie-down points and netting either side. To top it off, the fabric roof folds away into its own compartment, so the boot space is unaffected if you choose to drop the lid.

For a convertible – the Z4 is a practicality wizard.

While it’s a more luxurious Lotus, it remains a compact and impractical sports car - and that’s very much on brand. In terms of storage inside the cabin, there are two cupholders and a small lidded console box, but the size of the cabin means everything is quite narrow and feels a little tight for space.

There is a decent sized, although not very deep, shelf behind the seats, so you can put smaller, softer items there and hope they don’t slide around too much.

In terms of actual luggage space, there isn’t much. There’s a small boot behind the engine, and while deep, it’s pretty narrow so you’ll only get soft bags in there if you plan on taking your Emira on a road trip.

In terms of size and price, the Emira lines up almost directly against the Porsche 718 Cayman, which is a formidable adversary, but also the likes of the BMW M4. Notably, it’s significantly cheaper than anything offered by the likes of Ferrari, Maserati and McLaren.

The MY24 Emira range begins at $155,900, before on-road costs, for the entry-level model but stretches up to just over $206,000 for the i4 First Edition we’re driving here.

The Emira has been designed as a more premium and luxurious sports car compared to the stripped down and basic models of the recent past, such as the Elise and Exige, so it gets a range of items not previously seen on many Lotus models - such as carpeted floors and the choice of either Nappa leather or Alcantara trim.

Also included are LED headlights, climate control, keyless ignition, cruise control, rear parking sensors, a premium sound system and a 12.3-inch digital dashboard.

It's worth noting the MY25 Emira line-up was detailed earlier this month. You can read all about it, including pricing and specification, here.

Welcome to the age of ridiculously powered four-cylinder turbo engines. Despite a capacity of just 2.0-litres, the engine in the Z4 30i produces a whopping 190kW/400Nm.

That’s probably enough for a car this size. I’m keen to drive the six-cylinder, but surprisingly it seems to offer diminishing returns for extra cylinders offering a 60kW/100Nm power boost for an extra $20,000. Perhaps a six-cylinder is the way to go in a BMW, and given this car’s other seriously sporty attributes, it might be the only way to make it a bit more… fun. More on that in the driving section.

All Z4s are rear-wheel drive, using an eight-speed torque converter automatic. Sorry, no option for a manual this time around.

The MY24 Emria first arrived in Australia with the same Toyota-built 3.5-litre V6 engine Lotus had used in recent years in the likes of the Exige and Evora. However, this new AMG-built four-cylinder provides a fresh choice.

Importantly, while built by Mercedes-AMG, the tuning and calibration is unique to Lotus (but we’ll discuss that in detail later).

That means the 2.0-litre unit is tuned to make 268kW/430Nm, which is less potent than AMG offers in its 310kW/500Nm A45 hot hatch, although a more potent version of the four-pot Emira has been confirmed for MY25.

The engine is paired with an eight-speed dual-clutch auto transmission, which you can either leave in automatic mode or change gear manually using the F1-style paddles on the steering wheel.

It’s claimed that the Z4 will drink just 6.5 litres per 100 kilometres on the official combined cycle test, but I found that sticking my foot in occasionally resulted in a slightly more realistic sounding figure of 8.4L/100km.

That’s still a great fuel consumption number for a car like this, and perhaps one of the strongest benefits of having just four cylinders.

A discerning vehicle, the Z4 will drink nothing less than the best-quality 98RON unleaded to fill its 52-litre tank.

Given the Emira is a sports car, the four-cylinder turbo is tuned for performance over economy and that’s reflected in an 10.1L/100km return on the combined (urban/extra-urban) cycle. That’s not too bad for a sports car, but is relatively thirsty given the engine capacity and the overall size of the car.

The Emira is equipped with a 60-litre fuel tank, so it has a driving range of approximately 594km.

A car that looks this good better live up to the promise behind the wheel, right?

For the most part, the 30i does, but it’s a victim of its own performance credentials and luxuriousness.

See, a drop-top should be fun-packed, you should feel close to the road, connected. Sadly, a combination Z4’s excellent suspension and not-so-excellent SUV-like interior separates you too much from the surface below.

An advantage, of course, is the refinement on offer. The Z4 is easily one of the quietest, most refined convertibles I’ve ever driven, but it’s a little too insulated.

I can’t help but feel like it’s all business and no pleasure. It feels a little more like I should be cruising to work on the autobahn and a little less like I should be flinging it around corners on a tight B-road.

It feels almost wrong to drive it in a T-shirt. It’s serious and doesn’t want you to mess around, it wants you to wear a suit and tie.

This grand-tourer style feel is one that will keep a lot of buyers in the premium space happy, but I’m of the opinion that BMW will have that segment well and truly covered by the new 8 Series. If the budget allows.

Regardless, the 30i’s four-cyl engine feels like any six-cylinder would have a few years ago. It’s got a surge to it in the straights that’s quite satisfying, and it responds via the exhaust with an angry tone that makes it feel a little more alive, especially with the roof down.

This feeling was all helped along by our car’s M active differential which simply won’t let the fat tyres at the rear slide unless you’ve got high-speeds and loads of tarmac to play with – for better or worse.

The Z4 also has ‘variable sport steering’ which reacts to the car’s speed and position of the wheels to adjust the input ratio. It’s good when you’re at speed, but the weight and response of the steering can make the Z4 feel bigger than it actually is at lower speeds. 

The suspension is firm, and can be a little bouncy over rough surfaces, but seems well suited to the Z4’s chassis.

Other than those notable characteristics you’ll find that the Z4 is wonderfully tuned in terms of its inputs, everything is slick and smooth, suited perfectly for long meandering drives.

Just to be clear right up front, the score for this section is heavily biased towards the car's dynamic attributes, because frankly the Emira can be hard to live with at times.

At urban speeds the powertrain feels like a dog straining at its leash, which can result in some awkward moments.

For example, there were multiple instances where the gearbox refused to change out of second gear when exiting a roundabout, letting the engine rev quite hard and likely annoying my neighbours.

Some of the gear changes can be clunky too, not slotting as sweetly as they should on a sports car costing in excess of $200K.

However, you forget all that when you get the Emira onto a stretch of twisty, winding open road (preferably smooth tarmac) and move it from the 'Tour' to 'Sports' mode. The car comes alive, revving hard, shifting with precision and feeling like a puppy running through a field in pure ecstasy.

Like the great cars to come before it from Lotus, the Emira is in its element carving through corners. The steering is incredibly accurate, direct and responsive - as good as any sports car I’ve driven in recent memory. The chassis responds to those inputs with immediacy, too, feeling nimble, agile and engaging.

This is Lotus at its best.

Sports cars are not typically beacons of safety, not that they’re dangerous but the priority is speed, not complex and often weighty safety technology. It’s part of the reason these types of cars are rarely crash tested by the authorities, as is the case of the Emira.

But this more modern and luxury focused Lotus comes with a raft of safety items including adaptive cruise control, an anti-collision system (Lotus-speak for AEB), fatigue alert, road sign information, a vehicle speed limiter, lane departure warning, rear cross-traffic alert and lane change assist.

If recent quotes are anything to go by BMW is set to stick by its lacklustre three-year unlimited kilometre warranty, as it says its customers simply aren’t interested in five years (or longer) when it comes to warranty coverage.

It’s a shame, as even Volkswagen has upped its warranty to five years, and Mercedes has considered a 10-year coverage plan in the past.

In terms of servicing, there are two fixed-price plans available – the suspiciously cheap ‘Basic’ plan which comes at a cost of $1373 for five years (or $274.60 per year) and the more realistic-sounding ‘Plus’ which costs $3934 over five years (or $786.80 per year).

Like every other BMW, the Z4’s computer tells you when its service time: how often it needs maintenance will depend on how often – and how hard – you drive it.

Lotus Australia offers a three year warranty, which is in line with Porsche's cover, so that’s competitive in the sports car market. 

However, the brand does not offer capped price servicing, so you’ll need to discuss with your local dealer how much regular maintenance will cost you. The service intervals are every 12 months/15,000km.
