BMW 4 Series vs Toyota Prius C

What's the difference?

The BMW M440i xDrive Gran Coupe manages to combine sleek design with a fun-to-drive personality and surprising practicality. It’s a rapid premium, four-door, five-seater offering extra flair, and in this part of the market, good value. But more than anything else it’s got a cracking in-line six under the bonnet.

It's as if the the future is firmly rooted in the past at Toyota. The Prius is still undoubtedly clever, frugal and easy to drive, but it is feeling so old in places that the bad had begun to weigh on the good. If you're a tech-head or have a right foot crafted from lead, then there's nothing to see here. But if the thought of saving money at the bowser sets your heart aflutter, then step right this way.

So, how does this four-door 4 Series differ from a four-door 3 Series? The answer is as plain as the nose on this car’s face.

BMW’s head of design, Adrian van Hooydonk, has been expanding the brand’s signature ‘kidney grille’ in every conceivable direction, and this is the much talked about interpretation adorning all 4 Series models (petrol, hybrid and electric) as well as the M3 sedan.

The new Gran Coupe is longer, wider, and taller than the outgoing model, and the track is broader, front and rear. The wheelbase has also been extended, now a whole 5.0mm longer than the 3 Series.

The DRLs and headlight main beams are LED with laser high beams, immense gills square up the edges of the front clip, while a vent and the strake attached to it stand the car apart. Plus, of course, the doors are frameless. 

One niggle, though. I’m not in love with the slender door handles. It’s hard to get a good grip on them, especially in the wet. 

Standard 19-inch alloy rims are shod with Pirelli P Zero rubber 245/40 fr / 255/40 rr), the roofline slopes distinctly towards the rear, a lip spoiler on the trailing edge of the tailgate is classic BMW, darkened LED tail-lights wrap around the rear corner, and a diffuser-type panel is flanked by large exhaust apertures.

Our car’s ‘Aventurine Red’ finish is a $3850 option, but to my eyes anyway it looks superb.

Exterior trim including the grille frame, front air intake inserts, mirror upper housing, model designation badges, and tailpipe are finished in ‘Cerium Grey’, which I reckon 99.9 per cent of people will see as black. 

The interior will be familiar territory for any current BMW owner, the 12.3-inch digital instrument screen sitting in a compact, hooded binnacle, and partnering with a 10.25-inch multimedia display standing proud of the dash above the broad centre stack. 

The seats are trimmed in top-shelf leather with blue contrast stitching, plus the grippy sports wheel is also wrapped in genuine hide.

BMW calls the finish on the main buttons and controls ‘Galvanic’ which translates to a slick silver metallic look and feel. Configurable ambient interior lighting is a nice touch, and the broad console enhances the driver-focused feel, with a sprinkling of carbon-fibre around the centre console and dash lifting the sense of occasion.

Overall, the interior feels clean and classy with an obvious attention to detail.  

The good news is that it doesn't look quite so quirky as the full-size Prius. The not-as-good news is that it's still no beauty-contest winner. Not helping matters was the fact our test vehicle was painted in a retina-burning yellow (they call it Hornet Yellow, and it's new for 2018) that looked almost nuclear.

Viewed front on, the blacked-out section of grille and bumper gives the littlest Prius a vaguely manta ray-shaped front-end, while the headlights climb both upwards and back into the body, lending a sense of sportiness to this very unsporty hybrid. From the back, the chunky bumper, vertical taillights and rear windscreen spoiler all add a little attitude to the design.

Inside, you'll find a small but premium-in-places space, with a gloss-black stereo surround that angles the main controls toward the driver, while the digital driver's binnacle is pushed toward the centre of the car, displaying speed, fuel and other key info above the stereo, rather than in front of the steering wheel.

At close to 4.8m long the 4 Series Gran Coupe is a sizeable machine. Up front, the feeling is airy and comfortable, and the rear is surprisingly spacious, especially in light of the car's sloping roofline.

At 183cm I have to fold myself tightly to fit under the low roof, but once inside I have enough room to sit behind the driver’s seat set for my position with more than enough legroom and adequate headroom. Put three full-size adults across the back row, though, and there will be breathing difficulties.

Kids will be fine, however, and individual vents with adjustable temp in the rear was a big plus during a particularly hot test week.

For storage there are generous door bins in the front with room for large bottles, a decent glove box, dual cupholders in the centre console, a reasonable lidded bin (which doubles as a centre armrest), and the wireless device charging bay (forward of the gearshift) makes a handy oddments space when not in use.

In the rear, again the doors feature pockets with room for (medium-size) bottles, there’s a fold down centre armrest with two cupholders, but thanks to the one-piece shells on our test car’s optional M Sport front seats there are no map pockets.

Power and connectivity runs to a USB-A socket and a 12V outlet in the front centre console, as well a USB-C port in the front storage bin, a pair of USB-Cs in the rear, and a 12V outlet in the boot.

Speaking of which, lift the tailgate and with the rear seat upright we were able to fit all three of our suitcases or the beefy CarsGuide pram into the healthy 470-litre (VDA) boot space.

Lower the 40/20/40 split-folding rear seat down and 1290 litres of volume is at your disposal. Plus there are handy bag hooks and tie-down anchors to help secure loose loads.

You can also tow a braked trailer up to 1.8 tonnes (750kg unbraked), but don’t bother looking for a spare of any description, a repair/inflator kit is your only option.

Not very. This is a Yaris-based city car, let's not forget.

That said, it never feels cramped up front, with enough shoulder and headroom to ensure you feel separated from your fellow passengers, where you'll also find two cupholders, and an infuriating USB connection housed in the touchscreen - so your cord dangles from the dash when connected.

Climb into the back, and you'll find yourself in a pretty snug space. Sitting behind my own (5ft-8inch) driving position, it's only the scalloped back of the driver's seat that affords me any clear air between my knees and the seat in front, and the space behind my head and the roof lining is minuscule, too. But again, we're talking city car space here, so you can't expect to lounge about back there.

The ambience in the backseat leaves a little to be desired, though. The door trim pushes into the passenger space, and the plastics used in the rear are rock hard. There's a single cupholder to share, and a seat-back pocket on the rear of the passenger seat, but that's it; there's no vents, USB or power sources. There's no bottle-room in the rear doors, either.

An easy-access boot space will swallow 260 litres with the 60:40 rear seats in place. And there are two ISOFIX attachment points, one in each window seat in the back.

We've just spent a week behind the wheel of the Prius c i-Tech; the top model in the two-variant range, sitting above a cheaper model known simply as the Prius c.

At $26,540, it ain't cheap for a city car (and it's $4k more than the most-expensive Yaris on which it is based; more worryingly, it's only $1500 cheaper than an Audi A1), and the standard features list is more a novella than War and Peace.

Outside, you'll find 15-inch alloy wheels, remote unlocking, LED headlights and front fog lamps, while inside you'll leather-look seats (they're actually vinyl), sat-nav and climate-control.

Tech is covered by an  (old-school feeling) 6.1-inch touchscreen that pairs with a six-speaker stereo, but there's no Apple CarPlay or Android Auto.

Under the bonnet is BMW’s (B58) all-alloy 3.0-litre twin-scroll turbo intercooled, in-line six-cylinder engine, driving all four wheels via an eight-speed automatic transmission and electronically controlled clutch pack, as well as an electronic limited-slip differential at the rear.

It features high-pressure direct-injection and BMW’s ‘Valvetronic’ system managing air flow to the intake side, to produce 285kW at a relatively high 5800-6500rpm. But the big punch is 500Nm of peak torque from just 1900rpm all the way to 5000rpm.

The M440i is also a mild-hybrid with a 48-volt starter motor-generator and supplementary battery able to give an 8.0kW kick at low engine speeds.

Under that little hood lives a 1.5-litre, four-cylinder petrol engine good for 54kW, which pairs with a 45kW electric motor. Toyota lists combined outputs at 74kW at 4800rpm and 111Nm at 4000rpm.

That hybrid setup partners with a CVT automatic, pumping power to the front wheels.

BMW’s official fuel economy figure for the M440i xDrive Gran Coupe, on the ADR 81/02 - urban, extra-urban cycle, is 8.2L/100km, the 3.0-litre turbo six-cylinder emitting 187g/km of C02 in the process.

Stop/start is standard, and we saw an average of 11.1L/100km over city, B-road and freeway running during a week with the car.

With the 59-litre tank brimmed (with minimum 95RON premium unleaded) that real-world test number translates to a range of around 530km.  

If that last section didn't impress, this one surely will. The little Prius c will sip a claimed 3.9L/100km on the combined cycle.

That's very low, and the fact it accepts cheaper 91RON fuel makes it a very affordable car to run. Except... the onboard computers revealed a slightly less-impressive 5.1L/100km after my time with the car.

Emissions are a claimed 90g/km of CO2, which is very good.

BMW says the M440i xDrive Gran Coupe will accelerate from 0-100km/h in 4.7sec, and I reckon the threshold for a properly quick car is sub-five seconds.

The 3.0-litre turbo six develops its peak power of 285kW between a relatively lofty 5800-6500rpm, but the big number is a solid 500Nm punch of pulling power delivered between 1900-5000rpm.

Squeeze the throttle pedal pretty much anywhere in the rev range and the response is glorious. Rapid acceleration accompanied by raucous engine noise and rorty exhaust note (albeit with some synthetic support). Various pops and bangs in the Sport settings add extra entertainment.. 

The eight-speed auto gets some electric support from the mild-hybrid system to fill the torque gap on up shifts, and the result is a conventional torque-converter transmission that behaves like a dual-clutch.

Shifts are seamless in general driving, and satisfyingly quick in a more aggressive mode, the wheel-mounted paddles dialing up the fun in manual changes. 

Suspension is double wishbone front and multi-link rear with the standard ‘Adaptive M Suspension’ built around an adaptive damper set-up.

The change between the ‘Comfort’ setting to the ‘Sport’ or ‘Sport+’ calibration is close to instant and makes a discernible difference, especially in terms of ride comfort.

I found the best ‘Individual Sport’ arrangement to be damping in Comfort, with the steering engine and transmission in Sport. The car flows so beautifully through corners with urgent response from the powertrain.

By all means dial up the suspension if you’re having a real crack, but the car feels superbly balanced, stable and predictable in Comfort (front to rear weight distribution is 50:50).

The electrically-assisted variable-ratio steering is nicely weighted with good road feel, and the grippy sports steering wheel is a nice point of contact.

The xDrive AWD system’s default setting is rear-biased, although it will push most of the drive forward when required. But the RWD feel is unmistakable. 

The M440i weighs in at around 1.9 tonnes but feels lighter and more nimble than that figure would typically indicate.  

A standard electronically-controlled M Sport limited-slip differential puts the power down confidently. I have a favourite LSD test corner on my regular evaluation drive, a sharply twisting and rising left-hander.

Rolling into it in a low gear before planting the throttle mid-corner, the car simply hunkers down without a hint of fuss (or traction loss) as it rockets out the other side.

Optional M Sport front seats ($2000) provide comfort and firm location in equal measure and in terms of ergonomics BMW knows how to focus on the driver and set-up an efficient environment. Key controls are perfectly positioned and simple to operate.

I have an issue with the ‘Lane Departure Warning’ function, however, which is too quick to intervene and overly intrusive when it does so. I turned the ‘Steering Intervention’ function off. You can dial down steering wheel vibration warnings, too.

The standard M Sport brakes feature big vented rotors front and rear, with fixed four-piston front calipers doing the bulk of the work. They’re strong but don’t bite or release too aggressively. It’s easy to grease in a smooth application. 

In much the same way that you don't buy an exotic performance car for its ability to run to the shops, you're unlikely to be buying the Prius for its ability to set your pulse racing.

But happily, it doesn't feel wobbly or disconnected, either. It's aided by being such a small package, and when you're not wafting silently about in electric mode, and you've coaxed that little petrol engine into life, it serves up more than enough poke to navigate the city, and even to leave the slow-reactors in your rear-view mirror at traffic lights.

The ride is good, too, feeling connected to the road below without feeling uncomfortable, although the little Prius does tend to track with the corrugations in the road, leaving you to wrestle it back into line. That's a job made easier by light and surprisingly direct steering, which feels tailor-made for the city.

Finally, the leather-look seats are comfortable, even over long distances, the razor-thin A-pillars make forward vision easy and it's a very simple thing to drive and manoeuvre  into parking spaces. And all of those are good things.

Not so good? Well, the entire drive experiences feels a little beige and emotionless, it can get noisy and there are parts of the cabin that feel downright cheap. Worst of all, though, is that for a car that once heralded the future, it's feeling very, very dated.

But there are some amazing quirks attached to driving an (almost) electric car, including the delivery of eco awards for using the least amount of fuel (they were awarded for 2.6, 3.2 and 3.6L/100km over as much as 25km - none of which occurred during my tenure). The hardest thing to get used to was the absolute silence served up in electric mode. I counted four seperate occasions when I walked away from the car with it still turned on.

Every Prius c arrives with seven airbags, along with a reversing camera and... wait, that can't be it, can it? Oh... Forget AEB, lane-departure warning and the like, this future-focused Prius has a safety package firmly rooted in the past.

It was awarded the maximum five-star ANCAP safety rating, but was tested back in 2014.

The M440i Gran Coupe is covered by BMW’s three-year/unlimited km warranty (including paintwork), as well as 12-year/unlimited km anti-corrosion (perforation) cover. 

That’s off the premium market pace now with Genesis, Jaguar, and Mercedes-Benz at five years/unlimited km and Lexus set to join them from January 1st, 2022. 

That said, roadside assistance is provided for the duration of the main warranty, but it’s worth noting “rattles and squeaks” are only covered for one year.

Service is condition-based, the car telling you when maintenance is required, and a range of service packages are available. The basic plan covering a 4 Series for five years/80,000km comes in at $1750. 

Toyota offers a three-year/100,000km warranty, while the batteries are covered for eight years or 160,000km. The car's six-month service intervals might sting a little, though, but with each service capped at $140 for the first three years, even taking two trips to the dealership a year isn't too expensive. Just annoying.
