Jaguar F-Type VS BMW M4

Yep, no surprise, the 2021 Jaguar F-Type R is a proper, rip-snorting, beast of a machine. Weighing in at just over 1.7 tonnes, with 423kW/700Nm to propel it forward, in terms of straight line acceleration, it's every bit the scalded cat.

Bury the right foot and it will storm from 0-100km/h in just 3.7 seconds, with furious aural accompaniment courtesy of the 4.0-litre supercharged V8 and sports exhaust system. Electrically-actuated bypass valves in the latter's rear silencer remain closed until they automatically open under load, and boy, do they open up.

Prospective F-Type R owners wishing to remain on good terms with their neighbours will be pleased to know there's a 'Quiet Start function', but once you're a few blocks clear the engine is capable of alerting the entire suburb to you presence, complete with raucous crackles and pops on the overrun.

All 700Nm of maximum torque is available from 3500rpm through to 5000rpm, and mid-range thrust is ferocious. If you have access to a long enough private road Jaguar claims this car will storm on to a (electronically-limited!) maximum velocity of 300km/h.

The eight-speed auto transmission has picked up several tweaks courtesy of the XE-based SV Project 8, and it's brilliant. A conventional torque-converter based unit, rather than a dual-clutch, it's dubbed 'Quickshift', and that it does. Manual flicks between ratios, using the wheel-mounted paddles, are rapid and positive.

Head for your favourite B-road, and it's the F-Type R's ability to put every bit of its power down, without fuss, that impresses next. Push into a series of tight corners and the car grips, settles, and simply surges from one bend to the next, the tricky AWD system seamlessly shuffling torque between the axles and individual wheels.

The standard electronic active diff, and torque vectoring (by braking) also help keep everything under control, turning backroad tryhards into apex hunting virtuosos.

Suspension is by (aluminium) double wishbones front and rear, with revised springs and anti-roll bars added in the 2019 upgrade. Continuously-variable dampers underpin the 'Adaptive Dynamics' system, learning your style and adjusting accordingly.

The electrically-assisted power steering combines great road feel with satisfying accuracy, and the car feels balanced yet agile and responsive in enthusiastic driving.

In a more relaxed mode the adaptive set-up detects rough road conditions and adjusts the suspension settings for greater ride comfort. According to Jaguar, the damper valves and control algorithms have been recalibrated to improve low-speed comfort and high-speed control, and I can vouch for their effectiveness.

Not long after steering this F-Type R I spent some time in the supercharged V6 F-Type P380 R-Dynamic, and this R is far more compliant.

Rubber is a specially-developed Pirelli P Zero (265/35 fr - 305/30 rr), and the supremely efficient brakes are ventilated 380mm at the front, and 376mm rear.

Marvellously.

Earlier, we said that the previous M4 (and some earlier M3 generations) never hit the dizzy heights the best like the E46 managed.

The reason why is bandwidth. Not WiFi bandwidth, but rather the newfound breadth of capability that the G83 model has acquired.

Yes, while even the slowest examples of previous M3s and M4s remained thrilling, with blisteringly potent acceleration accompanied by a soaring exhaust soundtrack, the post-E46 models seemed to become almost too obsessed with the pursuit of performance. Thunderous V8s and twin-turbo V6s are all good and well, especially when they provide explosive responses, but there’s more to sports cars than sheer bloody-minded speed.

More specifically, though the handling and roadholding were outstanding, the previous M4’s steering didn’t feel as connected or one with the driver, instead seeming a little remote and detached. Conversely, even with adaptive dampers on offer, the suspension (on Australian roads) lacked sufficient isolation from bumps and thumps, and so was never settled or calm. It was all too nervous and edgy, like a drug-addled athlete who’s indulged in too much partying.

Thankfully, the curse is broken with the latest iteration, even in the heaviest and slowest version like our M4 Convertible as tested, pushing out boundaries to thrilling effect once more.

With the newly-simplified and logically presented M performance modes only a push of a button away, the driver now no-longer has to concentrate on what setting they’re in, and instead just immerse themselves in the experience of accelerating, steering, cornering, braking and controlling this incredible sports convertible.

Tremendously strong in regular Road mode, the M4’s performance certainly lives up to the legend, stepping up into the supercar realm when Sport or Track are chosen, hunkering down as it thrusts towards the horizon with relentless speed and determination, accompanied by the gorgeous twin-turbo six’s revs as they soar towards the red line. The ultra-alert eight-speed auto’s operation is equally seamless, displaying uncanny intuition in its selection of the right ratio at exactly the right time.

These are all incremental improvements over what has come before. But what’s really changed is how rock-solid the BMW feels as it belts along at speed, magnetised to the motorway regardless of weather, its new AWD engineering keeping everything steady and planted. No more tetchiness to unnerve the driver.

Which makes the feel and fluency of the chassis even more remarkable, given that now all four wheels are driven. The very opposite of leaden or inert, the superbly weighted steering is instead light and alive in your palms, as you carve through corners with pin-point precision. Some might find it a bit too eager to change direction at first, but we reckon BMW has judged the balance just right. Its sheer agility is as life-affirming for driving enthusiasts as it is immersive. Bravo, BMW.

With so much grip and control, this is not to say that the driver can’t hang the M4’s tail out every-which-way, since the chassis set-up allows for progressive oversteer, even in Road mode, along with as much drifting as your courage allows where safe. As with the best sports cars, the M4 is as steerable from the seat of your pants as it is using the throttle.

Finally, there’s the M Adaptive chassis tune, that at long last broadens the M4’s repertoire from motorway grand tourer and rural-road blaster to city slicker and urban warrior, thanks to the suspension’s ability to better-absorb a much wider array of terrible road surfaces. Comfort now lives up to its name, with the ride – though still firm – no longer hard or crashy around town, ushering in a new level of civility that won’t fatigue or aggravate you or your occupants. We're so happy to report this progress.

One area where BMW might want to keep improving, though, is the abundance of road noise intrusion over certain coarse chip bitumen. While easily muffled by the sweet sounds of the twin-turbo six, banging audio system or dropping the roof, it now seems more obvious that the rest of the car has smartened up so much.

A small fly in an otherwise hugely satisfying ointment.
