Ferrari 488 VS BMW Z4

We had the rare opportunity of driving the 488 Spider on road and track with Ferrari Australasia handing us the keys for a rural run from Sydney to Bathurst, followed by some private bonding time on the roads around town, then a batch of unrestricted hot laps on the Mount Panorama circuit in the lead up to this year’s 12 Hour race (which the scuderia won in emphatic style with the 488 GT3).

On the freeway, cruising at 110km/h with roof open, the 488 Spider is civilised and comfortable. In fact, Ferrari claims normal conversation at speeds over 200km/h isn’t a problem. Top tip (no pun intended) is to keep the side glass and small electric rear window raised to minimise turbulence. With the roof up, the 488 Spider is every bit as quiet and refined at the fixed roof GTB.

Even with the multi-mode Manettino in its regular ‘Sport’ setting and the seven-speed ‘F1’ dual-clutch gearbox in auto, all it takes is a gentle crank of the right ankle to despatch pesky road users with the temerity to impede the 488’s progress.

On the quiet, open and twisting roads around the outskirts of Bathurst we may have flicked the switch to ‘Race’, slipped the gearbox into manual and given the 488 Spider a nudge. In some sweeping corners on Mount Panorama we might have even tested Einstein’s theory that matter bends the fabric of space and time. In short, we were able to get a good feel for the car’s dynamic abilities, and they are monumental.

Relative to the 458, power is up a lazy 17 per cent (492 v 418kW), and turbo-fed torque leaps a staggering 41 per cent (760 v 540Nm), while kerb weight is trimmed by 10kg (1525 v 1535kg).

The result is 0-100km/h in 3.0 seconds (-0.4sec), 0-400m in 10.5 (-0.9sec), and a maximum velocity of 325km/h (+5km/h).

If you must know, given fuel efficiency and emissions performance was the key driver behind Ferrari’s move to a turbo powerplant, all this is balanced by claimed 11.4L/100km combined economy (down from 11.8 for the 458).

A full blown launch in this car is like lighting the wick on an Atlas rocket, with a seemingly never-ending surge of thrust pinning your back to the seat, and each pull of the column-mounted carbon gear paddle delivering a seamless and near instantaneous shift. Ferrari claims the 488’seven-speed ‘box shifts up 30 per cent quicker, and down 40 per cent faster than the 458’s.

The lofty summit of the twin turbo’s torque mountain arrives at just 3000rpm, and once you’re up there it’s a table top rather than a peak, with more than 700Nm still on call at close to 7000rpm.

Maximum power arrives at 8000 (perilously close to the V8’s 8200rpm rev ceiling), and the delivery of all this brute force is impressively refined and linear. To improve throttle response, the compact turbos incorporate ball-bearing-mounted shafts (rather than the more common sleeve bearing type), while the compressor wheels are made from TiAl, a low-density titanium-aluminium alloy. As a result, turbo lag simply isn’t in the 488’s vocabulary.

And what about the sound? On its way to 9000rpm the 458 Italia atmo V8’s rising fortissimo howl is one of the world’s greatest mechanical symphonies.

Maranello’s exhaust engineers allegedly spent years fine-tuning the 488’s aural output, developing equal length tubes in the manifold to optimise harmonics before gas flow reaches the turbos, to get as close as possible to the high-pitch wail of a naturally aspirated Ferrari V8. 

All we can say is the 488’s sound is amazing, immediately turning heads on contact... but it ain’t no 458.

Using the 488 Spider’s incredible dynamic ability to translate forward momentum into lateral g’s is one of life great pleasures.

Supporting the double wishbone front and multi-link rear suspension set-up is a host of high-tech widgets including the tricky E-Diff3, F1-Trac (stability control), High-Performance ABS with Ferrari Pre-Fill, FrS SCM-E (magnetorheological shock absorbers), and SSC (side-slip control).

Combine that with the active aero quietly turning the car into a four-wheel suction cup, plus ultra-high performance Pirelli P Zero rubber, and you have amazing grip (the front end especially, is incredible), perfect balance and stunning corner speed.

Our Mount Panorama blat confirmed the 488 Spider remains poised and throttle steerable through corners and curves at ludicrous speeds.

Chasing gears into the top of the ‘box up mountain straight made the lights on the upper rim of the steering wheel look like a fireworks display. The Spider transmitted its every move across the top of the circuit through the lightweight seat, and the very fast blast into The Chase at the bottom of Conrod Straight was other-worldly. Set the car up on entry, keep squeezing the throttle, grease in just a fraction of steering lock, and it just blazes through like a high-speed hovercraft, at 250km/h-plus.

More time back outside Bathurst confirms feel from the electro-hydraulic rack and pinion steering is brilliant in the real world, although we did notice the column and wheel shaking in our hands over bumpy backroads.

The quick fix there is a flick of the ‘bumpy road’ button on the steering wheel. First seen on the 430 Scuderia (after then Ferrari F1 hero Michael Schumacher pushed for its development), the system de-links the shock absorbers from the Manettino setting, providing extra suspension compliance without sacrificing engine and transmission response. Brilliant.

Stopping power comes courtesy of a ‘Brembo Extreme Design’ system derived from the LaFerrari hypercar, which means standard carbon-ceramic rotors (398mm front, 360mm rear) clamped by massive calipers - six piston front, four piston rear (our car’s were black, for $2700, thank you). After multiple stops from warp speed to walking pace on the circuit they remained firm, progressive, and hugely effective.

A car that looks this good better live up to the promise behind the wheel, right?

For the most part, the 30i does, but it’s a victim of its own performance credentials and luxuriousness.

See, a drop-top should be fun-packed, you should feel close to the road, connected. Sadly, a combination Z4’s excellent suspension and not-so-excellent SUV-like interior separates you too much from the surface below.

An advantage, of course, is the refinement on offer. The Z4 is easily one of the quietest, most refined convertibles I’ve ever driven, but it’s a little too insulated.

I can’t help but feel like it’s all business and no pleasure. It feels a little more like I should be cruising to work on the autobahn and a little less like I should be flinging it around corners on a tight B-road.

It feels almost wrong to drive it in a T-shirt. It’s serious and doesn’t want you to mess around, it wants you to wear a suit and tie.

This grand-tourer style feel is one that will keep a lot of buyers in the premium space happy, but I’m of the opinion that BMW will have that segment well and truly covered by the new 8 Series. If the budget allows.

Regardless, the 30i’s four-cyl engine feels like any six-cylinder would have a few years ago. It’s got a surge to it in the straights that’s quite satisfying, and it responds via the exhaust with an angry tone that makes it feel a little more alive, especially with the roof down.

This feeling was all helped along by our car’s M active differential which simply won’t let the fat tyres at the rear slide unless you’ve got high-speeds and loads of tarmac to play with – for better or worse.

The Z4 also has ‘variable sport steering’ which reacts to the car’s speed and position of the wheels to adjust the input ratio. It’s good when you’re at speed, but the weight and response of the steering can make the Z4 feel bigger than it actually is at lower speeds. 

The suspension is firm, and can be a little bouncy over rough surfaces, but seems well suited to the Z4’s chassis.

Other than those notable characteristics you’ll find that the Z4 is wonderfully tuned in terms of its inputs, everything is slick and smooth, suited perfectly for long meandering drives.
