Mercedes-Benz S-Class VS Lotus Exige

In former times, as the Germans say, a ‘450' on the boot indicated V8 power. In the W116 S-Class era it was one of the world's most evocative badges when ‘SEL' was also attached.

As mentioned earlier, though, it's the M256 3.0-litre turbo-petrol with a 48-volt ‘mild hybrid' electrical system that's doing the driving, to all four wheels. The real V8 W223 will probably surface later this year or in early 2022 with the S580L flagship. Bring it on.

This is not to say that S450 isn't good enough. With that electrified assistance, the blown straight six is smooth and swift off the line and rapid as the auto seamlessly steps up through all nine gears. Because it's so hushed and refined, it doesn't feel 5.1s to 100 clicks quick, but watching the speedo says otherwise – acceleration is assertive and strong right up way past the legal speed limit.

All that's missing is the burbling soundtrack of a classic Benz bent-eight. Oh well. Outstanding economy is a price we're literally willing to pay in lieu.

Even more impressive is the S450's ability to hustle along mountain roads like an overgrown sports sedan.

Now, for Australia, all S-Classes are fitted standard with an adaptive ‘Airmatic' air-suspension set-up, including air springs and self-levelling tech. In Comfort up to 60km/h, the ride height can be raised by 30mm, or lowered by 10mm under the standard 130mm baseline in Sport at any velocity, while in Sport+ it falls another 17mm.

With that in mind, yes, the standard air suspension performs a magnificent job smothering out most surface imperfections around town. Yet its real other party trick is to tighten up the chassis when corners get interesting and Sport mode is selected. Aided by progressively weighted and reassuringly responsive steering, the Mercedes tips into turns with precision and poise, slicing through with virtually no discernible body lean or understeer.

Now, we're not talking a leisurely drive on rural highways here, but Healesville's famous Chum Creek Road, where even a Porsche Cayman would feel like it's had a strenuous dynamic workout. The S-Class can be hurried along with confidence and finesse, displaying outstanding handling and roadholding for a 5.2-metre long limo. And the fact that the ride quality only suffers marginally when the red horns are out is all the more remarkable.

Back in the cut-and-thrust of inner-city peak-hour traffic, the Benz in Comfort mode continued to reveal its driver-orientated yet passenger-focused twin-personalities, zipping in and out of gaps while remaining comfy and composed inside.

Only when parking in tight spots are you truly aware that the W223 is longer than a Mazda CX-9. The optional four-wheel-steering system is claimed to slash the turning circle to A-Class hatchback levels. 10.9 metres is the claim.

The 2021 S-Class never ceases to amaze and delight.

It's rare to find a car that is such an improbable mix of furious fun and infuriating annoyance. The Lotus is rattly, noisy, hugely firm to the point of punishing, with seats that offer encouragement but not support.

It is the opposite of comfortable and so hard to see out of that driving it around town, in any sort of traffic, feels borderline dangerous. There’s also the distinct sensation that you’re so low and so little that all those people in their SUVs won't see you.

Throw in the fact that it's so painfully, stupidly difficult to get in and out of and it's definitely not the sort of car you take if you're heading to the shops. I got so sick of its hard-edged annoyances at one stage that I became too grumpy to even take people for joy rides in it. I just couldn’t be bothered with the hassle, but then an inner-city suburb with high kerbs and even higher speed humps is not the Exige's natural environment.

Making it even more of a challenge around town, at low speeds or in parking situations is the steering, which isn't so much heavy as wilfully obtuse. Doing a three-point turn is the equivalent of 20 minutes of bench pressing your own body weight. At least.

Out on a winding bit of country road, however, the steering becomes one of the best things about the car, because its pure, unassisted weighting feels so alive in your hands. There’s a sense of actually wrestling, or finessing it around corners that makes you feel a bit Ayrton Senna.

Indeed, the whole car comes alive, and starts to make some kind of sense, once you're on a smooth, perfect piece of tarmac. It is fast, noisy, thrilling, utterly and overtly involving, stiff of chassis and firm of ride, with brakes capable of pulling you up with indecent haste. It’s also, thanks to its low centre of gravity and mid-engined layout, beautifully balanced.

The gearbox is a thrill a minute, as is the engine, particularly once you explore the upper rev ranges, at which point the scenery really does become a scary blur out the ridiculously small windscreen.

Sure, you can't see anything behind you other than the engine, but what a lovely sight that is, and nothing is going to catch you anyway.

It does feel edgy, of course, and sharp, and it’s not as easy or refined to drive as some cheaper sports cars; an MX-5 makes for a far more pleasant companion. But this is an extreme Exige, a machine built by and for genuine enthusiasts.

And, above all, for the sort of people who will take it to a race track, which is where it both looks and feels completely at home.

Unfortunately, on public roads, it would be annoying more often than it would be thrilling, but the truly hardcore Lotus aficionados would never admit such a thing.
