Kia Ev4 vs Porsche 718

What's the difference?

An electric sedan is really shrinking the buyer pool, which is why Kia has such gentle expectations for the EV4 in Australia. But it's a lovely driving EV with plenty of perks, and the design alone will brighten up Australia's roadways. For my money, I'd either be going for the cheapest one that's sharp value with plenty of kit, or the flagship GT-Line that gets the big battery and the works in terms of equipment. The Earth for me sits in no-man's land.

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 slippery-looking unit that adorns this page is the EV4 sedan. There’s also a hatch, but it comes out of Europe, while this one comes out of Korea, and that would likely make the hatch far more expensive than this bad boy. It's under study, apparently, but yet to be confirmed.

Anyway, to steal a hackneyed football analogy, for mine this is a game of two halves. I actually really like the front end. It looks sleek and slippery and there’s a real presence from the swollen arches.

I am, however, a little less sold on this rear end, which looks sharp and blocky and almost like it has been bolted on. Also annoying is the fact that it looks like it should be a liftback, with the boot hinged up above the rear windscreen. But nope, it's hinged below it, so you still get a dinky little opening to squeeze your stuff through.

Kia's international designers are pushing the boat out at the moment, and they deserve credit for making things different. Whether it sinks or swims with the general public, though, will be the real test.

Inside, it's all pretty traditional Kia, with all three models sharing the twin 12.3-inch digital displays, along with the little climate panel in the middle. Kudos to Kia for keeping some physical buttons, too. I'm less sold on the use of some cheap, hard plastics, even in the top-spec cars.

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.

At 4730mm long, 1860mm wide and 1480mm tall, the EV4 sits between the Model 3 and the Seal in terms of its outright dimensions. Kia says the EV4's wheelbase and interior packaging has been designed to maximise backseat space, which I must admit, there is plenty of.

Sitting behind my own 175cm driving position, I had miles and miles of leg room, and enough head room, though there is some kind of optical illusion that occurs in the backseat of the EV4 – even though you definitely have enough space, the dark materials of the GT-Line still leaving me feeling a little claustrophobic somehow.

Something else not to be sneezed at is the inclusion of the household-style power plug in the back. My laptop died while I was taking notes on my test, and I plugged it straight in and powered it up. Super handy.

At the back, there is 490 litres of boot space, which is about middle ground. The Seal is more like 400 litres, but the Model 3 offers more.

Sadly the EV4 is yet another EV that does not have a spare wheel of any kind. Instead you have to make do with a tyre repair kit.

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.

All EV4 models are front-wheel drive, with a single front-mounted motor producing 150kW and 283Nm, fed through a single-speed gearbox. That’s enough, Kia says, to knock off the sprint to 100km/h in around 7.5 seconds. The Air is the fastest, at 7.4s, while the heavier Earth and GT-Line claim 7.8s. Top speed is a claimed 170km/h.

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.

Let’s talk about range for a moment, because it's bloody impressive. Not quite the best out there, but the furthest any electric Kia has ever travelled between charges.

There are two battery options, a 58.3kWh NCM battery in the Standard Range, and a 81.4kWh unit in Long Range models. The Standard will deliver 456kms in driving range, but the Long Range ups that to 612kms, both on the WLTP cycle. 

The EV4’s 400-volt architecture does slow down charging a little, though, with DC fast charging capped at 128kW. That means going from 10 to 80 per cent in around 30 mins when using the fastest chargers. If you’re using a 50kW charger, it’s up to almost an hour and 20 minutes for the bigger battery, which is a long coffee stop.

Plugged in at home, provided you have an 11kW wallbox, it’ll take just under five and a half hours, or just over seven hours, to go from 10 per cent to fully charged, so an overnight charge no matter the battery size.

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.

I learned something new and exciting (well, to me, at least. You might be very bored) from Kia's ride and handling guru on this launch. And that is that the tuning frequency for common city road imperfections, like bridge expanders, is actually the same as for the bigger, bouncier undulations you get on country roads. And so you can tune to prioritise one or the other, not both.

In real terms, it means a car that feels custom-built for the city, gliding over urban roads with mega comfort (which is exactly what the EV4 does), feels slightly less at home out of town, where there is more obvious movement in the cabin.

Bored yet? Ok, the point is that, while never uncomfortable, the EV4 feels right at home in the city, which is where it's expected to spend most of its time, but weirdly firmer on longer adventures. 

This really is easy, city EV motoring, done well. There's no alienating floatiness to the ride, no lifeless lightness to the steering, it's comfortable, quiet and – despite no headline-grabbing power figures – more than potent enough to get you up and moving.

There's nice weight to the steering, and though the front tyres gave up their grip a couple of times when pushed with some steering lock on, there isn't much in the way of aggressive body roll, and it all feels pretty confidence inspiring. 

The power is most effective from around 10km/h to 80km/h, before the urgency starts to fall away – it's slower to respond at freeway speeds – but that too just leans into its city credentials.

There's really not much to complain about here. It feels well sorted, and quite fun to drive. There is nothing that really stands out as spectacular about the drive experience, but nor is there anything to complain about. It's just really solid motoring, which isn't always guaranteed these days.

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.

Kia ownership proposition is simple, and pretty strong. You get a seven-year warranty no matter how far you travel, an eight-year warranty for the high-voltage systems, again no matter how far you travel, and capped-price servicing. Pre-paying your service costs will set you back $688 for three years, just over $1300 for five years, or just under $2000 for seven years.

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.
