BMW 230i vs Porsche 718

What's the difference?

The BMW 2 Series coupes and convertibles combine understated good looks with great dynamics and top-shelf quality. Extra equipment, especially the iDrive6 multimedia system, has brought it up to speed in terms of tech and value, while the M240i sets the compact performance benchmark. And if you really want to push the envelope, the M2 is right there at the top of the under $100k performance pyramid.

If this is to be the end of the 718 as we know it, then it is an end to be remembered. Porsche has produced something special in the Spyder RS, a sports car that can compete with the 911 on any stretch of road - which is something so few cars can claim. The focus on performance has driven the entire concept of the car, but all the elements work in harmony, with form and function coming together.

The biggest visual clue to the revised 2 Series is the circular design bi-LED headlights, now standard on the 2 Series entry 220i, and mid-range 230i models, while hexagonal adaptive LEDs are standard on the top-shelf M240i.

But BMW couldn't leave those little light-emitting diodes alone, with LED front fog lights joining one-piece L-shaped LED tail-lights across the range.

Luxury Line-equipped cars feature a subtly revised nose treatment with larger intakes and a reshaped 'kidney' grille. There are also four new alloy wheel designs – a 17-inch alloy fitted standard to the 220i Luxury Line, and three optional M alloys for M Sport models (all no-cost options on the M240i).

The 230i M Sport features black, high-gloss bars in its kidney grille, as well as a black chrome finish for the exhaust finishers.

On the inside, there's the addition of a 'Black Panel' digital instrument cluster, which remains matt with the ignition off, and lights up with sharp graphics, configurable across conventional speed and rev readouts, as well as gear position, engine-efficiency data, vehicle settings and nav guidance.

There are also high-gloss finishes across the centre stack and front console, and even greater attention to detail around panel joins, trim stitching and switchgear.

But the hero is the latest iDrive6 multimedia system, run through an 8.8-inch colour touchscreen (6.5-inch on 220i), providing access to live content, radio and audio, navigation and maps, phone functionality, and vehicle settings through a simple and customisable app-style interface. The iPhone really as inspired car companies.

The M2 boasts M-specific instrument display content and a go-fast red needle on the tachometer.

As the pinnacle of not only the current 718 range, but potentially the entire combustion engine era of the Boxster, Porsche has pulled out all the stops for the Spyder RS.

This includes major changes to the design, but none are purely for aesthetic reasons and instead are driven by the search for performance; and the fact they make the 718 look tougher, meaner and more purposeful than ever before is just a bonus.

It’s a comprehensive redesign that starts at the bumper with a new front lip spoiler to enhance downforce. Then there’s a pair of NACA ducts on the lightweight bonnet to improve brake cooling without compromising aerodynamic drag. The lightweight front fenders include wheel arch vents to stop any potential for front-end lift at high speeds.

And the fenders aren’t the only component that’s gone on a diet, there’s a lighter exhaust, lighter wheels, lighter bonnet, lighter roof, lighter door panels and even lighter carpets on the inside. All up, the Spyder RS tips the scales at 1400kg, which is 40kg lighter than a standard 718 Boxster.

If it’s still not light enough, you can opt for the optional 'Weissach Package' (which was fitted to our test car), which brings even lighter 20-inch forged magnesium wheels and carbon-fibre reinforced plastic for a range of parts including the front luggage compartment, rollover bars and ducktail spoiler on the Gurney flap – plus some cosmetic enhancements.

And we still haven’t even touched on the biggest design change yet - the rear half of the car. Starting with the roof, which Porsche actually calls a ‘sunshield’ and ‘weather guard’ because it’s a stripped down version of what the brand usually uses, to save weight and let the glorious engine noise into the cabin uninterrupted.

But it’s also necessary because the entire rear engine cover has been redesigned to accommodate the larger engine that Porsche has installed in the Spyder RS, a 4.0-litre six-cylinder instead of the usual turbocharged four-cylinder ‘boxer’ engines.

While the Spyder RS looks great with the roof/sunshield on or off, frankly the removal process is much too complicated and requires repeated viewings of a YouTube tutorial to still get it wrong.

While owners will (likely) eventually get the hang of it, it will always be a clunky and awkward process and that’s just the price of being so focused on performance, which you can accept or not.

Inside that ethos of performance over practicality continues, with sports seats, an Alcantara-wrapped steering wheel and even the previously mentioned lightweight carpet floor mats.

It’s a purposeful, rather than luxurious, cabin, but that perfectly suits the nature of the Spyder RS. Our test drive included several long stretches behind the wheel and at no stage did it feel uncomfortable or impractical, despite its stripped-down design.

Surprisingly, at a little over 4.4 metres long, the 2 Series (Coupe) is around 10cm longer than its 1 Series hatch stablemate (M240i +15cm), but aligns with its just under 1.8m width, and 1.4m height.

It seats four, with plenty of room up front and multiple storage options, including two cupholders in the console with an oddments tray behind, a 12-volt outlet, a lidded storage box between the seats with USB connection, a reasonably sized glove box, and segmented bins in the doors big enough for large water bottles.

While it was coupes only on the launch drive, we know the convertible has a pair of cupholders in the back, but not so in the coupe, and while headroom in the soft-top is okay (especially with the roof down) it's a squeeze in the hardtop.

More a 2+2 than a full four-seater, getting into the rear is an athletic exercise, and once installed, leg and headroom for this 183cm tester is tight. That said, kids up to teenager-size would be fine.

Boot volume is 390 litres (a 3 Series Coupe is 480 litres), with run-flat tyres on the 220i and 230i meaning there's no spare (or repair kit) under the floor, but the performance-focused M240i and M2, pack a 'BMW Mobility Kit' (compressor and tyre sealant to cover minor damage) in line with their high-performance (non-run-flat rubber).

A 60/40 split-folding rear backrest liberates extra load space, and a 'Through Loading System' with luggage compartment dividing net, and 40/20/40 split-folding rear seat is optionally available (220i & M2 Pure - $350 / 230i - $385 / M240i & M2 - $500).

And if you're keen on towing the 220i can pull 680kg of unbraked trailer, and 1500kg braked, with the minimum number stepping up to 715kg for the 230i. The M240i and M2 are no-tow zones.

One area where the 718 range is starting to show its age quite dramatically is the in-car technology. While Porsche’s native system is relatively user-friendly, the lack of wireless Apple CarPlay or Android Auto in any capacity is deeply out-dated; and was frustrating for this Android using reviewer.

Given the age of the current 718 platform, and the impending arrival of the new model, it’s understandable that the multimedia system didn’t get an overhaul, but for a $350K car it does feel a bit behind the times.

In practical terms the Spyder RS is a bit of a struggle if you plan to go away with it. We managed to get a small suitcase and backpack in the under bonnet storage, but that was at capacity. While the addition of the larger engine removes any meaningful rear storage space.

The bad news is, the Spyder RS costs just over $200,000 more than the entry-level 718 Boxster, which is not a small sum of money. The good news is, for that $200K, Porsche has overhauled the 718 from nose-to-tail and enhanced it in nearly every aspect.

There’s a raft of mechanical changes that we’ll get to later on, to help justify the $334,200, plus on-road costs, asking price, but from a specification perspective there are some notable inclusions. 

For starters it comes with the 'Porsche Communication Management' (PCM) multimedia system, which includes in-built navigation and Bluetooth connectivity, as well as a 110-watt sound system.

But Australian delivered cars get an even higher level of standard equipment than other countries, with LED headlights including 'Porsche Dynamic Light System' (PDLS), cruise control, digital radio, rear 'ParkAssist' with reversing camera, 'Light Design Package', tyre fit set and windscreen with grey top tint, plus a no-cost optional Bose Surround Sound System all included.

It may be $200K more than 718 but compared to a 911, it actually makes a pretty compelling value argument. A 911 Cabriolet Carrera S starts at $342,700 (plus on-road costs), making that Spyder RS $8500 cheaper and a genuine alternative to its ‘big brother’.

Then, when you compare it against similar mid-engine European sports cars, such as the Maserati MC20 (from $510,000) or McLaren Artura (from $477,310) the Porsche looks like a bargain; relatively speaking, of course.

The 220i is powered by a 2.0-litre 'TwinScroll' turbo-petrol four, featuring 'Valvetronic' variable valve control and 'Double-VANOS' variable camshaft control, and developing 135kW at 5000rpm, and 270Nm between 1350-4600rpm.

Using a retuned version of the same engine (lower compression ratio, more turbo boost), the 230i pumps out a solid 185kW at 5200rpm, and a grunty 350Nm from just 1450-4800rpm.

The same (8HP50) eight-speed auto transmission is used across the board, pushing drive to the rear wheels only.

Then, the M240i is powered by a 3.0-litre, six-cylinder, turbo-petrol, pushing out no less than 250kW at 5500rpm, and a thumping 500Nm between 1520-4500rpm.

The same (8HP50) eight-speed auto transmission is used across the board, pushing drive to the rear wheels only, and happily, a six-speed manual gearbox is a no-cost option on the M240i.

The full-house M2's 3.0-litre turbo six produces 272kW at 6500rpm, and 465Nm from just 1400-5650rpm (500Nm from 1450-4750rpm on overboost), driving the rear wheels through a seven-speed dual-clutch auto, although a six speed-manual is a no-cost option (and standard on the M2 Pure).

The key stat for the engine is the cylinder count. Gone are the four cylinders and instead it’s a return to Porsche’s iconic flat-six.

Specifically, the same 4.0-litre six that Porsche uses in its 911 GT3, which is a lot of engine to squeeze into the middle of this lightened sports convertible.

In order to keep the 718 in its place (beneath the 911), Porsche has slightly detuned the engine, so it makes 368kW/450Nm (compared to 375kW/460Nm in the 911 GT3), but the German brand has never worried about a kilowatt contest and instead prefers to focus on driveability and the other elements that make a drive great.

To that end the combination of air-intakes next to the headrests and the lightweight stainless steel exhaust (which gets titanium tips on the Weissach Package) helps the Spyder RS sound like a Carrera Cup racing car when you really wind it up to its 9000rpm redline.

Not that the performance isn’t spectacular, though, with Porsche claiming it takes the Spyder RS just 3.4 seconds to run 0-100km/h, only 10.9 seconds to get from 0-200km/h and will hit a top speed of 308km/h.

The engine is paired to a seven-speed dual-clutch auto transmission (or PDK in Porsche-speak) that the company claims has “short-ratios”, but with peak power not hitting until 8400rpm and peak torque from 6750rpm, you don’t have to rush the ratio changes.

Claimed fuel consumption for the 220i Coupe, on the combined (ADR 81/02 - urban, extra-urban) cycle, is 5.9L/100km, emitting 135g/km of C02 in the process. The 220i Convertible rates 6.1L/100km (140g/km).

The 230i Coupe is line-ball with that at 5.9L/100km (134g/km), and the the 230i Convertible at 6.2L/100km (142g/km).

The price of performance starts to bite with the M240i consuming 7.1L/100km (163g/km) in coupe form, and 7.4L/100km (169g/km) as a convertible.

Then, as you might expect, the M2 is thirstiest of all, the dual-clutch auto consuming 7.9L/100km (185g/km), while the six-speed manual version slurps 8.5L/100km (199g/km).

Auto start-stop is standard, fuel tank capacity is 52 litres across the board, and although technically these engines can run on anything from 91-98RON unleaded, BMW recommends 95RON premium as a minimum.

Porsche says the 4.0-litre engine in the Spyder RS uses 13.0L/100km, which is a big number for what is a relatively small car. But that engine is highly-tuned and built for performance not efficiency, so it’s something owners will need to accept.

Our test drive included some long highway stretches, as well as some spirited driving and urban commuting, so a good mix across all conditions, and we saw consistent returns around the 15-16L/100km range.

It has a 64-litre tank, which means a theoretical driving range of around 490km, assuming you can hit the official claim.

Four 2 Series variants were offered for the launch drive program, a 230i Coupe (which BMW nominates as the most popular model in the range), M240i Coupe, M2, and M2 Pure.

Claimed 0-100km/h acceleration of 5.6sec for the 230i M Sport Coupe is quick, with the convertible stopping the clocks three tenths later.

Peak torque of 350Nm is plenty, and with that number available from 1450-4800rpm the mid-spec 2 Series is an entertaining drive.

It's M Sport (strut front, five-link rear) suspension keeps the body well buttoned down in quick going, while the beefier M brakes provide strong and progressive stopping power.

Even a firm squeeze of the throttle can't side-step some hesitation as the turbo spools up before right foot pressure translates into forward momentum, but despite the sporty tune, ride quality is good (even riding on notoriously harsh 18-inch run-flat rubber), while response and road feel from the variable-ratio steering are excellent.

The eight-speed auto is beautifully slick, with manual changes, via wheel-mounted paddles, sharp and positive.

Add the grippy leather sports wheel, snug sports front seats, and racy cloth/Alcantara trim (leather in the convertible), and you have a comfortable, nicely balanced and fun-to-drive package.

Accelerating from 0-100km/h in 4.6sec (convertible 4.7sec), the M240i effortlessly achieves 'genuinely rapid' status. Yes, it's fast, but never furious, in the sense that even under the pressure of enthusiastic peddling it remains civilised and composed.

Maximum torque of 500Nm is not to be sneezed at, and when you realise that mountainous maximum is actually a flat-top plateau stretching from only 1520rpm up to 4500rpm, satisfying urge is never far away. And the flexible 3.0-litre turbo-six is an aural treat as it howls its way towards a 7000rpm rev ceiling.

The standard 'Adaptive M Suspension' offers settings from 'Comfort' through to 'Sport+', but even in the most forgiving mode the car remains taut and communicative.

The 18-inch rims, shod with Michelin Pilot Super Sport rubber (225/40 front / 245/35 rear) don't upset the ride as much as you'd expect, although coarse-chip surfaces send rumble through to the cabin.

In terms of ergonomics and general function, the new iDrive6 system is simple and intuitive to use, the current BMW dash and console layout is a model of efficiency, but the two-stage (depress small button on stubby lever, then shift) process to select drive or reverse can be a frustratingly hit-and-miss affair if you need to get going quickly.

Then, the M2 is all business, with a properly focused feel, and the ability to accelerate from 0-100km/h in a claimed 4.5sec for the six-speed manual, and just 4.3sec for the seven-speed dual-clutch. Try not to smile as that g-force shoves you back in your seat. You won't succeed.

Although peak power arrives at a relatively high 6500rpm, maximum torque of 465Nm (500Nm for limited periods on overboost) is ready for action across a broad spread from 1400-5650rpm, so the M2 has adrenalin flowing through its veins at all times.

An electronically controlled 'Active M Differential' manages torque distribution across the rear axle to optimise power down, with the ability to send anywhere from zero to 100 percent of drive to either back wheel.

The 'M Servotronic' steering, switchable through comfort and sport modes, is feelsome and linear in its response, the mega 'M Compound Brake' package (borrowed from big-brother M4) is professional grade, and while the seven-speed dual-clutch may shift faster, snicking up and down the manual's six ratios is a rare pleasure.

Rolling on 19-inch, ultra-high-performance Michelin semi-slick rubber (255/35 front / 275/35 rear) the M2 is never going to waft like a limousine, but if you're signing on for this kind of performance and dynamic ability, some ride harshness over less than perfect surfaces goes with the territory.

I’m only giving it a nine out of 10 because perfection is hard for any car to achieve, but the 718 Spyder RS goes as close as any car I’ve driven. This is a masterpiece of modern sports car design, pushing the 718 closer to the 911 than ever before, which is something Porsche has clearly tried to avoid so as to not tarnish the image of its flagship.

But with the 911’s 4.0-litre flat-six in the middle of the 718, plus its more compact dimensions, the lightweight nature of the Spyder RS and the raft of chassis and handling enhancements, this really does leave you questioning ‘do I really need a 911?’

The steering is fantastically direct, the chassis responds to every input with precision and feedback and the braking is strong and consistent. Which helps because that engine is so good it launches you with ferocity and a glorious noise (as good as anything on the market today) whenever you squeeze down on the accelerator.

The highest praise I can give the Spyder RS is not that it was a dream to drive on winding, challenging roads, but that it was just as enjoyable on a trip to the shops or cruising down the freeway. Any drive in this car is a genuine pleasure.

This is another area where the 718 is showing its vintage, with very little in the way of active safety features. There’s the required stability control, as well as airbags for driver and passenger, plus the previously mentioned reversing camera. But that’s it, there’s no autonomous emergency braking, no lane-keeping assist or even adaptive cruise control.

While that may sound shocking to some, there’s never a moment where you feel unsafe in the 718. It feels incredibly stable and responsive on the road, as the onus falls back upon the driver to pay attention and make smart choices.

There’s no ANCAP rating for the 718, or any Porsche, so it is a question of putting your faith into Porsche’s in-house safety measures.

BMW uses 'condition-based' servicing, with the car effectively telling you when it's time to visit the workshop, but the 'BMW Service Inclusive' program offers distance and time options to fix maintenance costs (on a 'Basic' or 'Plus' plan) for up to 10 years/200,00km.

For example, a five year/80,000km service package for the 2 Series costs $1340 for the Basic option (oil service/top-up, annual vehicle check, microfilter, air filter, fuel filter, brake fluid, spark plugs), and $3550 for the Plus pack (adds brake pads and discs, wipers rubbers, and clutch disc and plate).

The standard BMW warranty covers three years/unlimited km.

It’s difficult to give the Spyder RS a clear score here because Porsche is cagey on the details. The public dealer websites indicate annual oil maintenance is required, with additional servicing every two years or 15,000km. 

How much that will cost is unclear, as despite the rest of the 718 range having publicly available prices, there were no such details for the Spyder RS (or even its Cayman sibling, the GT4 RS).

For reference, the 'standard' 718 requires oil maintenance ($895) for the first annual service and an inspection ($1500) the year after. Those costs continue to alternate annually out to eight years/120,000km.
