BMW 320d vs BMW 128TI

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.

It might not be rear-wheel drive, but the 128ti is a thoroughly enjoyable BMW to steer, proving the 'f' in front-wheel drive can stand for fun. It’s a very good hot hatch.

And given how expensive mainstream hot hatches have become, the 128ti is a bargain, giving would-be Golf GTI, Focus ST and i30 N buyers a thing or two to think about.

After all, the 128ti is a premium hot hatch by virtue of the BMW badges it wears and the higher quality of its parts, but not its price. And for that reason, it cannot be ignored.

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 can count me among those who aren't fans of the 1 Series' version of BMW’s 'kidney' grille. It’s not just out of proportion, but arguably, misplaced.

In fact, it just spoils the front end, although I'm also not a fan of the bumper's 'smiling' centre air intake.

But, thankfully, that’s where my unfavourable opinion ends, as the angular headlights and hexagonal DRLs look the part, while the 128ti's red-trimmed side air intakes bring a sense of occasion.

And you better be a big fan of red trim, as the 128ti liberally applies it around the side, where the brake calipers have some presence behind the attractive 18-inch Y-spoke alloy wheels. And don’t forget the side skirt insert and 'ti' decal!

At the rear, aside from the obligatory '128ti' badge and the relatively subtle red-trimmed side air intakes, there isn’t much to separate the 128ti from a garden variety 1 Series, but that’s no bad thing as it's its best angle.

The sporty rear spoiler, sleek tail-lights, stupendous diffuser insert and scintillating dual exhaust tailpipes are gorgeous. And the 128ti is attractive in profile, thanks to its appealing silhouette and smoothly sculpted lines.

Inside, the 128ti stands out from the 1 Series crowd with the red stitching applied to the steering wheel, seats, armrests and dashboard, while the floor mats have – you guessed it – red piping.

The most interesting design flourish, though, is the red-stitched ti logo on the centre armrest. That's one way to make a statement, and it all combines to make the 128ti feel special.

And being a 1 Series is a leg-up in the first place, as high-quality materials are used throughout, in concert with a simple but effective design.

Mercifully, the centre stack features physical climate and audio controls, while the centre console has an appropriately sized gear selector and a rotary dial to control the multimedia system.

That's right, the 128ti has multiple input methods aside from the 10.25-inch central touchscreen and voice control, making it a relative breeze to operate, especially with Apple CarPlay and Android Auto support of the wireless variety.

That said, there's plenty of room for improvement for the 128ti's 10.25-inch digital instrument cluster, which lacks the breadth of functionality of its competitors.

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.

Measuring 4319mm long (with a 2670mm wheelbase), 1799mm wide and 1434mm tall, the 128ti is a small hatchback in every sense of the term, but it makes the most of its size.

The boot's cargo capacity is competitive, at 380L, although it can be increased to a more accommodating 1200L by stowing the 60/40 split-fold rear bench.

Either way, there's a decent load lip to contend with, but four tie-down points, two bag hooks and a side storage net are on hand for securing loose items.

In the second row, there's a welcome four centimetres of legroom behind my 184cm driving position as well as a centimetre or two of headroom, even with our test car’s optional panoramic sunroof.

Three adults can sit on the rear seats on short journeys, but they will have next-to-no shoulder-room, plus a large central tunnel (necessary for AWD 1 Series variants) to deal with.

Young children are accommodated, though, with two ISOFIX and three top-tether anchorage points available for fitting child seats.

Amenities-wise, those in the back have access to the storage nets on the front seat backrests, clothes hooks, the centre console's directional air vents and two USB-C ports.

The door bins can take a regular bottle each, but there isn't a fold-down armrest with cupholders.

Up front, the glove box is surprisingly large, while the driver-side cubby is not only decently sized, but two-tiered. The central storage bin is also solid, and has a USB-C port hidden inside.

Ahead of that are a 12V power outlet, a pair of cupholders, a USB-A port and a narrow, open cubby that should house a wireless smartphone charger (but doesn't). And yes, the door bins are ready to swallow a regular bottle apiece. So, pretty damn good overall.

Priced from a tempting $55,031, plus on-road costs, the 128ti finds itself right in the thick of the hot-hatch action, with its M135i xDrive big brother at least $10,539 dearer, while its most direct rival, the Golf GTI, is just $541 cheaper.

Of course, more affordable FWD hot hatches are available, and they're more potent than the 128ti and GTI, including the Ford Focus ST X ($51,990) and automatic Hyundai i30 N Premium ($52,000).

Either way, the 128ti stands out from the 1 Series crowd with its bespoke steering tune, lowered sports suspension (-10mm), black grille, unique two-tone 18-inch alloy wheels with 225/40 Michelin Pilot Sport 4 tyres, upgraded brakes with red calipers, and black side-mirror caps.

There's also red trim on the front and rear air intakes, and side skirts, with 'ti' decals positioned above the latter. The steering wheel, seats, armrests, dashboard and floor mats have similarly coloured accents.

Other standard equipment includes a body kit, dusk-sensing adaptive LED headlights, rain-sensing wipers, a tyre repair kit, power-folding side mirrors with heating and puddle lights, keyless entry and start, a 10.25-inch touchscreen multimedia system, satellite navigation, wireless Apple CarPlay and Android Auto support, digital radio and a six-speaker sound system.

And then there’s a 10.25-inch digital instrument cluster, a 9.2-inch head-up display, dual-zone climate control, a sports steering wheel, power-adjustable front sports seats with memory functionality, an auto-dimming rearview mirror, black/red cloth and synthetic leather upholstery, 'Illuminated Boston' trim, ambient lighting and M seat belts.

Options include a $3000 'Enhancement Package' (metallic paintwork, panoramic sunroof and adaptive cruise control with stop and go functionality), which was fitted to our test vehicle for an 'as tested' price of $58,031.

Other key options include a $1077 'Convenience Package' (power tailgate, boot storage net and ski port), a $2000 'Executive Package' (alarm, rear privacy glass, 10-speaker hi-fi sound, gesture control and tyre pressure monitoring) and a $1023 'Comfort Package' (heated steering wheel, and front seats with lumbar support).

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.

The 128ti is motivated by a familiar 2.0-litre turbo-petrol four-cylinder engine, with its version producing a promising 180kW of power at 6500rpm and 380Nm of torque from 1500-4400rpm.

Disappointingly, Australian examples are detuned relative to their European counterparts, which are 15kW/20Nm more potent due to their market-specific set-up.

Either way, drive is sent to the front wheels via a dependable ZF eight-speed torque-converter automatic transmission (with paddle-shifters) and a determined Torsen limited-slip differential.

This combination helps the 128ti sprint from a standstill to 100km/h in a brisk 6.3 seconds while on the way to a not-in-Australia top speed of 243km/h.

For reference, competitor outputs are: M135i xDrive (225kW/450Nm), Golf GTI (180kW/370Nm), i30 N Premium (206kW/392Nm), and Focus ST X (206kW/420Nm).

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 128ti's fuel consumption on the combined cycle test (ADR 81/02) is a promising 6.8L/100km, while its carbon dioxide (CO2) emissions are 156g/km.

However, in real-world testing, I averaged a reasonable 8.4L/100km over an even combination of urban and highway driving. Without my heavy right foot, an even better return could be had.

For reference, the 128ti's 50L fuel tank takes more expensive 98 RON premium petrol at minimum. Its claimed driving range is 735km, but in my experience, I got 595km.

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, can a FWD BMW be fun to drive? As far as the 128ti is concerned, the answer is a resounding yes.

Yes, you get the feeling you’re being pulled rather than pushed, but the 128ti attacks corners with entertaining vigour.

Of course, the 2.0-litre turbo-petrol four-cylinder engine’s 180kW/380Nm outputs can easily overwhelm the front wheels off the line, and torque steer is a threat, particularly when pushing hard around bends, but they’re welcome characteristics.

After all, corner exits are improved by the 128ti’s Torsen limited-slip differential, which works hard to optimise grip when you need it most.

When going for the jugular, understeer still rears its ugly head, but wrestling the 128ti into shape is half the fun.

That said, body control isn't quite as strong as hoped. Turn in sharply and the 1445kg 128ti generates a surprising amount of roll.

It’s worth noting the lowered sports suspension goes without adaptive dampers, its fixed-rate set-up attempting to find the delicate balance between comfort and dynamic response.

All in all, the 128ti's ride is firm but well judged, with short, sharp imperfections the only real bother. Needless to say, it’s capable of being a daily driver, and so it should be.

As mentioned, the electric power steering has a unique calibration, and it's nice and direct, with a good amount of feel. But if you prefer more heft, simply engage 'Sport' mode.

Speaking of which, the Sport drive mode also releases the full potential of the engine and the eight-speed auto, sharpening up the throttle and raising the shift points.

The 128ti engine is a gem, offering up plenty of punch, especially throughout the mid-range, where torque is at its fattest and power is about to peak. The accompanying soundtrack also has some presence, even if it is artificially 'enhanced.'

But the smooth yet relatively quick shifting automatic transmission can take plenty of credit for the brisk performance on offer.

That said, the 128ti's first and second ratios are surprisingly short, so pay attention if you take matters into your own hands via the steering wheel’s paddle shifters.

The 128ti and the wider 1 Series range received a maximum five-star rating from independent Australian vehicle safety authority ANCAP in 2019.

Advanced driver-assist systems in the 128ti extend to autonomous emergency braking (AEB) with pedestrian and cyclist detection, lane-keep assist, cruise control, speed sign recognition, high-beam assist, driver attention alert, blind-spot monitoring, active rear cross-traffic alert, park assist, rear AEB, a reversing camera, front and rear parking sensors, and 'Reversing Assistant.'

That said, annoyingly, adaptive cruise control with stop and go functionality is part of the 128ti’s optional Enhancement Package fitted to our test vehicle, or as an individual option.

And tyre pressure monitoring is tied to its extra-cost Executive Package. Both should be standard.

Also included are six airbags (dual front, side and curtain), anti-skid brakes (ABS) and the usual electronic stability and traction control systems.

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 BMW models, the 128ti comes with a three-year/unlimited-kilometre warranty, which is two years off the five years/unlimited km premium benchmark set by Audi, Genesis, Jaguar/Land Rover, Lexus, Mercedes-Benz, and Volvo.

The 128ti also comes with three years of roadside assistance, while its service intervals are average, at every 12 months or 15,000km, whichever comes first.

Capped-price servicing packages are available, with three years/40,000km starting from $1350, while five years/80,000km kicks off at $1700. The latter, in particular, offers great value.
