BMW 320d vs Mini Cooper

What's the difference?

Despite BMW's wholehearted embrace of the SUV its 3 Series is still a critically important model for the brand in Australia. And this new version certainly has the spec and tech to take the fight up to Merc's C-Class. And if you're in the happy position of making that choice, it's now a whole lot harder. For our money the 330i marks the sweet spot with extra performance, safety tech and standard features for only a fraction more than $3k over the 320d entry-point.

The new petrol Cooper range very gently evolves the upmarket Cool Britannia cliché BMW invented with the R50 back in 2001 and fostered with every iteration since.

More of the same, only slightly updated and just improved enough to justify trading the old one in. If this appeals to you, then go for it. This is the best petrol version yet. Probably.

But the Cooper’s real spark literally and metaphorically lies within the EV version.

Two very different Minis indeed.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

At just over 4.7m nose-to-tail the new 3 Series has crept 76mm in overall length but that dimension is still more than 200mm shy of its next-size-up 5 Series sibling.

Changes to the exterior design are more evolutionary than revolutionary. You're never going to mistake this car for anything other than a BMW 3 Series.

But even if the face is familiar, aerodynamic efficiency is outstanding. BMW admits its claimed Cd of 0.23 was achieved with a base model running on 17-inch wheels (not offered here), but even if bigger rims knock a few fractions off that number it's still an amazing result for a conventional four door sedan.

Big contributors are a full width front spoiler, 'air curtains' managing flow around each corner of the nose, almost complete sealing of the largest areas underneath the car, and a functional rear diffuser section.

The signature kidney grille has grown and is delivered as a single piece, with active shutters incorporated to manage cooling air flow through to the engine. Twin adaptive LED headlights (standard on all models) feature a sharp notch on their lower edge, a big clue for new model spotters.

Broad, carefully managed surfaces characterise the bonnet and flanks of the car, with a distinct character line just above door handle height enhancing its confident stance.

The slightly smoked L-shaped LED tail-lights sit proud of the body, and 18-inch alloys are standard on the 320d, stepping up to 19s on the 330i.

The interior has been redesigned with revised controls and new materials, including slick 'aluminium teragon' finish on the console and dash in the M Sport.

As you can see in our interior images, it's been tidied up and simplified considerably, although it will still be instantly recognised by current BMW drivers.

Highlights are a 12.3-inch configurable digital 'Live Cockpit Professional' instrument display (lifted directly from the X5), a new 10.25-inch media touchscreen and a standard (larger) head-up display.

You’ve got to hand it to BMW.

The new nose and triangular tail-light treatment on the 2013-vintage midsection look as if they were designed to all go together back in the day.

You could even mistake it for the previous Cooper EV, though side-by-side that’s less likely, since the latter ditches the upright windscreen for a more raked item, clamshell bonnet opening, horizontal bumper shutlines for shorter and more-angled ones, plastic wheel arch surrounds and pull-out door handles for flush units.

The wheels are further apart, the overhangs shorter and the lower-side surfacing broken up by an artful sheetmetal crease.

The overall length at 3876mm, width at 1744mm and height at 1432mm have increased by 55mm, 17mm and 18mm respectively over the old model, but the 2495mm wheelbase stays the same.

And that’s not all.

A longer wheelbase (+41mm) has helped increase overall cabin space and rear room specifically.

There's plenty of storage provided with a large lidded box between the front seats as well as two large size cupholders in a recessed section in front of the gear shift (which can be closed off with a roll-top style cover).

The glove box is large and there are big bins in the doors with separate holders for full-size bottles.

Rear legroom is generous. At 183cm, sitting behind my own driving position, there was plenty of fresh air between knees and seatback, with lots of foot room to boot.

Headroom was more marginal with a straight back leading to a bonce/roof interface. But there are adjustable rear vents, twin cupholders in a fold-down centre armrest, and big bottle holders in the doors. Multiple USB ports (Type A and Type C) and a 12-volt power outlet are provided front and rear.

The boot space offers up a 480-litre luggage capacity with a 40/20/40 split-folding rear seat increasing cargo flexibility. Local towing capacity is yet to be confirmed, but indicative (European) ratings for both models are 750kg for an unbraked trailer and 1600kg braked.

Standard rubber is run-flat so there's no spare of any description.

The previous Mini 3DR featured a messy and quite overbearing dashboard design from 2013 that’s aged about as well as Robin Thicke’s videos from that year.

In contrast, the new model's is far simpler and less protruding, dramatically boosting the sense of space and light.

That said, all four occupants still sit low, with an upright windscreen ahead and beside high window sills. There’s an oversized, circular screen in the middle of a pared-back dash and a neat row of toggle switches below. It’s still pure Mini in theme.

As before, there’s enough space for even the tallest people up front, reflecting the British icon’s German packaging, with plenty of head and legroom, as well as ample width. It’s only when you jump from the EV to the petrol Cooper that you realise this feels noticeably narrower.

All Coopers regardless of fuel share the 240mm (9.4-inch) central OLED display. It might seem like visual overload at first glance, with so much going on, but after a brief period of familiarisation, the touchscreen becomes a cinch to decipher and navigate. The colour-coded driving modes, pleasingly slick screen swipe action and ultra-crisp graphics are especially noteworthy.

Revel, too, in the twist engine starter and toggle gear selector actions, that also save space and are super natural to operate. This is button-lite dashboard de-cluttering done right.

As with the previous model, the Mini’s driving position has you sitting upright, but it’s comfortable enough on the S’ sports seats we sampled this on, and everything is within reach. There’s sufficient storage. The ambient mood lighting is fun. And kudos for the deployment of animal-free materials. In fact, the Cooper’s fresh textures are quite remarkable.

We’re less fond of the glass roof with no sunlight block; there are blind spots due to the thick side pillars; and some of the lower-placed plastics do not seem $60K’s worth in a supermini this expensive.

Rear-seat access isn’t graceful, with a narrow aperture to squeeze past and a slow-moving electric seat to wait for, but that should surprise nobody given this car’s size. There’s enough space for two adults and not much else really. It’s pretty basic back there.

And even further back, Mini quotes just 210 litres VDA of luggage capacity, rising to 725L with the twin backrests dropped.

Don’t forget, though, that no spare wheel exists. Just an ever-fiddly tyre repair kit.

Meanwhile, at the other end of the Cooper…

For the duration of the original BMC/BLMC/Leyland/Austin/Rover era, the Mini was often the cheapest new car around. We’re talking bare bones motoring here, for the people.

Obviously, BMW bothers with no such democratic notion today.

The new Cooper comes in two models differentiated by engine size – the C with a 115kW 1.5-litre three-cylinder turbo and S with a 150kW 2.0-litre four-cylinder turbo. Both are carryover units, and automatic only, sadly. 

Which helps explain why the base C Core starts from a steep $41,990 (all prices are before on-road costs). Much the same car cost $10K less just five years ago.

The Core includes climate control air-conditioning, an OLED circular touchscreen, a head-up display, a reverse camera, parking sensors, wireless Apple CarPlay/Android Auto, DAB+ digital radio, a smartphone charger, ambient lighting, a heated steering wheel, 17-inch alloy wheels and a basic cruise control set-up.

You’ll need to step up to the $44,990 Cooper C Classic for adaptive cruise control, a surround-view monitor, interior camera, 'augmented reality' satellite navigation, front seat warmers, seven rather than four colour choices, 18-inch alloys, a glass roof and more.

'Sun Protection Glazing' for the latter, along with a Harmon/Kardon premium audio system, John Cooper Works (JCW) sports seats with electric adjustment and memory, fancier interior materials and a broader palette of options are part of the Cooper C Flavoured package from $47,990. 

Meanwhile, the more-powerful Cooper S auto bypasses Core and kicks off with the Classic from $49,990, Favoured from $52,990 and the JCW Sport from $54,990.

The latter includes a JCW body/interior styling, steering wheel and stripes, along with adaptive suspension, paddle shifters and uprated brakes.

Going for the 5DR Cooper equivalents adds $2000 to the price.

All up, then, with drive-away pricing, the Cooper before options is priced between $47,000 and $63,000.

Obvious rivals are the Audi A1, Fiat/Abarth 500, Citroen C3 and even Suzuki Swift Sport, though alternatives with a retro bent and driver focus might also be in BMW’s crosshairs, including the Toyota GR86, Subaru BRZ, Mazda MX-5, Ford Mustang and Nissan Z.

The 320d is powered by a 2.0-litre four-cylinder twin-turbo-diesel, featuring common-rail direct-injection and variable inlet timing. It produces 140kW at 4000rpm and 400Nm between 1750-2500rpm.

The turbo's multi-stage design incorporates a small, high-pressure, fixed-vane turbocharger as well as a larger, low-pressure, variable-vane turbo to maximise response, performance and efficiency.

A 2.0-litre single turbo-petrol four-cylinder engine sits under the 330i's bonnet incorporating direct-injection, as well as variable valve and cam timing. Peak outputs are 190kW from 5000-6500rpm and 400Nm between 1550-4400rpm.

Mark the date because this is the first time the BMW 3 Series has been offered in Australia without a manual gearbox option. Both launch models send drive to the rear wheels via an eight-speed automatic (with wheel-mounted shift paddles) only.

Compared to the previous model, the new one brings more performance to the table.

The Cooper C uses BMW’s 1.5-litre three-cylinder turbo petrol engine, and pumps out 115kW of power at 6500rpm and 230Nm of torque from 1500rpm to 4600rpm. Previously it was 100kW and 220kW.

With a power-to-weight ratio of 91.3kW per tonne, it’s enough for a zero to 100km/h time of 7.7 seconds (previously 8.1s), on the way to a 225km/h top speed.

Mounted transversely, it drives the front wheels via a seven-speed dual-clutch transmission (DCT).

It’s still difficult to imagine Mini buyers not outraged by the manual’s disappearance. But don’t worry. There’s always the Suzuki Swift.

Stepping up to the Cooper S, you’ll find a 2.0-litre four-cylinder turbo-petrol unit delivering a useful 150kW at 6500rpm and 300Nm between 1450rpm and 4500rpm. It was 141kW/280Nm in the old version.

Boasting 117kW/tonne, this one needs just 6.6s to 100km/h and can achieve a 242km/h V-max.

Now known as the FAAR platform, it is an evolution of BMW’s UKL (Untere Klasse, German for ‘lower class’) modular architecture that debuted in the previous model.

Suspension is via MacPherson-style struts up front and a multi-link independent rear end.

Despite each car's performance potential claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is commendably low.

BMW says the 320d delivers excellent diesel fuel economy, consuming a miserly 4.5L/100km, emitting 119g/km of CO2 in the process, with the 330i's fuel consumption figure coming in at 6.4L/100km and 147g/km.

You'll need minimum 95 RON premium unleaded in the 330i, with both petrol and diesel requiring 59 litres to fill the tank to full capacity.

The new Coopers enjoy a drink more than before. By almost half a litre per 100km more, in fact.

Rated at Euro6 and running on 95 RON premium unleaded petrol, the Cooper C averages 6.0L/100km (F56: 5.6), while the more-powerful Cooper S ups that to 6.3L/100km (F56: 5.8).

In terms of carbon dioxide emissions averages, this translates to 137 and 145 grams per kilometre, respectively. With a 44L fuel tank, the potential range-average is up to around 730km.

First, the performance figures. BMW claims the 320d will accelerate from 0-100km/h in 6.8sec, which is agreeably quick, while the 330i knocks that down to 5.8sec, which is properly fast.

Both engines deliver the same 400Nm of maximum torque at low rpm; 1750-2500rpm for the 320d, and a broader 1550-4400rpm spread for the 330i. Mid-range acceleration is strong and satisfyingly linear in each, the 330i that bit more urgent at the top end.

The eight-speed auto is velvety smooth, with the wheel-mounted shift paddles on hand for rapid 'manual' changes. Engine noise is muted at low revs but nice and rorty under pressure.

A stated aim in the development of this 3 Series was "dynamic engagement", and the standard strut front, multi-link rear suspension has been tuned to reinforce the driving part of the brand's long-standing 'ultimate driving machine' promise.

The standard suspension includes tricky two-stage dampers front and rear, but with all cars at the local launch fitted with the optional active damper system we'll have to wait to report on its quality (or otherwise).

This car's centre-of-gravity is 10mm lower than the model it replaces, which may not sound like much, but in engineering terms, absolutely is. In concert with a perfect 50:50 front-to-rear weight distribution, and wider tracks front and rear, it helps deliver an overall planted feel and predictable cornering balance.

The electro-mechanically assisted steering is accurate and linear with good road feel, which is not always the case in recent Beamers.

The launch fleet was also rolling on 19-inch rims (standard on 330i, optional on 320d) shod with Bridgestone Turanza run-flat rubber (225/40f - 255/35r) and despite that type of tyre's reputation for harsh characteristics and a moderate level of road noise, ride comfort on the typically coarse rural roads we covered in the Victorian high country was impressive.

Braking on both models is by ventilated disc front and rear, and even in spirited cornering maintained their power and efficiency. The M Sport brake package fitted to the 330i dials things up with four-piston alloy calipers (sourced from Brembo) up front.

The standard sports steering wheel is fat and grippy, the sports front seats combine firm location with long-distance comfort and overall noise levels are low. Overall, this is a super-impressive touring car.

So far, similarities in design, packaging, dashboard presentation and suspension layout suggest that the electric Cooper and petrol Cooper would be like fraternal twins from behind the wheel.

But in reality, the petrol-powered Mini feels much the same as the previous model, whilst the EV is more akin to what we secretly wish the fantasy Tesla Model 1 would be like. From the future.

Now, we never had a chance to drive the Cooper C, but the closely-related (though larger and heavier) Countryman C sibling – complete with the same powertrain – proved to be a willing and feisty performer once on the go, after what seemed like protracted turbo and DCT lag.

Why the hell can’t Mini just offer manuals again?

The Cooper S, meanwhile, completely lived up to brand expectations, with the familiar, revvy snarl of BMW’s sophisticated 2.0-litre four-pot turbo providing punchy of throttle response and effortless cruising capability, though there’s still some initial acceleration hesitation.

Thankfully, the Mini’s steering is always alert, offering precision and agility by the bucketful, backed up a chassis that seems permanently glued to the road – even in the wet and wintry conditions we had to endure.

Yet, other than a ride quality that seemed better than any previous-gen Mini we’ve ever encountered and so genuinely surprised us, the Cooper S seemed a little… stale compared to the glorious SE EV we had just (reluctantly) surrendered.

A bit like having a favourite dish as leftovers for two nights in a row, it felt a bit passé in 2024, even when surrounded by that dazzling OLED dash and glitzy ambient lighting.

In every important metric – performance, handling, roadholding, ride quality, packaging and (particularly) refinement – the battery-powered Cooper is the more vibrant and alive option. And truer to the vision of the original’s creator, Alec Issigonis, as a result.

There are no crash-test ratings for the 2024 Cooper at the time of publishing.

The previous F56 managed four out of five stars with ANCAP. 

On the driver-assist tech front are AEB, lane departure warning, lane keep assist, blind-spot monitoring, rear cross-traffic alert with braking, rear-collision prevention, driver-attention monitor, tyre-pressure monitor, auto high beams and an exit warning.

However, at the time of publishing, no AEB operating parameter data was available.

Other safety features include adaptive cruise control with automatic speed-limit assistance from Classic-grade and up, anti-lock brakes, electronic stability and traction controls and nine airbags (front/side/head and interaction centre-front airbags).

A pair of child seat tether latches and twin ISOFIX latches are fitted within the rear seats.

BMW offers a three year/unlimited km warranty, which is drifting off the pace now with the majority of mainstream brands stepping up to five-year cover, with some at seven.

On the upside, bodywork is covered for 12 years, the paint for three, and 24-hour roadside assistance is complimentary for three years.

Servicing is condition based, so the car tells you when maintenance is required, and BMW offers a range of service packages in 'Basic' and 'Plus' grades up to 10 years/200,000km.

Like all Minis, the Cooper comes with a five-year/unlimited kilometre warranty and five years of roadside assistance.

There are no set service intervals, as the car’s onboard computer will alert the driver based on condition and wear/tear. That said, we recommend going every 12 months or 10,000km, just to be on the safe side.

Mini also promotes several prepaid service plans on its Australian website. According to BMW, “… both new and used Mini owners can upgrade to a MINI Service Inclusive plan for 5-years/80,000km (whichever comes first).”
