New vs used: Jaguar F-Type and Audi R8 head-to-head

Both have double wishbones all round and engines that are longitudinally oriented, of all-aluminium construction, equipped with variable cam timing and displace around 500cc per cylinder, but that’s where the conformity ends.

The Jag’s front-mounted Ingenium four-pot is force-fed its oxygen and drives the rear wheels alone via an eight-speed automatic gearbox – you can’t have it any other way on the 2.0 F-Type. Its 296bhp is dwarfed by the R8’s 424bhp, and it takes 5.4sec to reach 60mph; the Audi is already at 62mph after 4.6sec.

Thanks to the Jaguar’s twin-scroll turbo, twist is a closer call at 295lb ft against 317lb ft. Yet just as the F-Type’s maximum torque band ends at 4500rpm, the naturally aspirated R8’s is only just beginning, and the B7 RS4-sourced V8’s redline sits way up at 8000rpm – a full 1700rpm higher than in the Jaguar.

The R8’s four-wheel-drive system is rear biased, but could the F-Type’s absolute dependence on its back axle and 110kg weight advantage provide a dynamic edge in the face of its power deficit? Even Neckarsulm acknowledges as much these days, Herr Winkelmann describing the recently revealed lightweight, rear-drive R8 V10 RWS as “made for purists”.

We’ve gone for a stick-shift R8 on the basis that the automated-manual six-speed R-tronic available in 2011 would age the driving experience terribly versus the F-Type’s thoroughly modern eight-speed ZF torque converter. (The seven-speed S-tronic dual-clutch ’box didn’t enter the R8 until its 2012 facelift.)

It’s the Audi’s aluminium troublestirrer that forms its interior’s centrepiece. Chunky, gnarled and cold, it juts proudly out of the equally striking open aluminium gate like an oversized honey dipper by Krups. Its quality and flamboyance aren’t really echoed elsewhere, though.

Yes, the red leather seats are softly upholstered, handsome and supportive but, like the steering column, they adjust manually, there are lots of plastic surfaces and the switchgear doesn’t have the lithic heft of Audi’s current range. While this particular car’s living quarters are absolutely immaculate, their design is a decade old and goes to show how interior quality standards – and expectations – have risen since 2007. Despite numerous optional extras including sat-nav and parking sensors, the Audi misses out on the Jag’s DAB, cruise control, rain and dusk sensors too.

The F-Type’s cabin feels slightly cosier but it’s plusher too, with stitched hide on parts of the fascia where the R8 manages with softtouch plastic, electric adjustment to seats and steering column and hard plastics more discreetly applied. The seats are nicely finished in leather and Alcantara-like ‘suedecloth’ – they’re firm but enveloping and nestle a little lower than the R8’s.

Then there’s the 8in touchscreen with sat-nav – it’s too deeply set into the dash but is understandably more feature-packed and graphically sophisticated than the Audi’s dial-controlled 6.5in MMI system. Likewise, the F-Type’s supplementary colour 5in TFT in the instrument binnacle trumps the R8’s little mono display. Switchgear is of broadly comparable quality between the two.

When it comes to stowing your lifestyle accoutrements, there are more hiding places in the Jag, and its liftback boot reveals a long, 300-litre space that gains 108 litres with the parcel shelf removed; the Audi’s front boot swallows only 100 litres, but at least it’s usefully deep.

So, what about this highly strung little engine in the Jag? A warm-up growl sets its stall out at ignition and low-speed manoeuvres bring a fair bit of engine noise and exhaust bellow, whether or not you have the muffler baffles open.

Below 2000rpm, there’s little action to be had, but then you get a steady and sturdy delivery of thrust most of the way to 6200rpm, the augmented induction noise turning positively racy without ever troubling the hairs on your nape. Off-throttle crackles spit from the exhaust, rising to an ack-ack barrage in Dynamic mode.

There’s palpable turbo lag, but not of the binary severity you might once have feared from an engine offering 148bhp per litre; it’s perfectly manageable. The eightspeed auto ’box governs itself well, choosing gears sensibly in normal mode and keeping revs usefully high in Sport. The override paddles echo the ZF’s electronically controlled slickness with their unmechanical, microswitchy feel.

Even in the transmission’s most heightened setting, downshifts are subject to a short delay, though upshifts are unrelentingly rapid. It will let you rev to 7000rpm, but there’s little point; between B-road corners you have all the pep you need further down, though the engine’s modest capacity is revealed when looking for an extra surge between fast sweepers.

The same can’t be said of the R8, which always has plenty to give – all you have to do is let it rev. A pleasant start-up woofle grows into a more authentic growl than in the Jag, gaining in aggression and intensity as the tacho rises.

The V8 pulls without protest from idle but really kicks above 4000rpm and is still giving as the needle passes 7000rpm. All the while, you can hear and feel how much more action the engine’s internals are seeing, and how much physically closer they are to you than in the F-Type.

The aluminium gearstick’s action feels as enjoyably mechanical as it looks, and sounds like a hammer striking a steel pin as you drive it home. Yet each shift is resolutely a two-stage action that will not be rushed, exacerbating the inter-gear delay the R8 suffers versus the automatic F-Type.

On our test route’s tight twisters, that proved a little obstructive but was somewhat offset by the pleasure of instant throttle response that allowed an indulgent heel and toe with the slightest brush of the right-hand pedal.

Jaguar claims to have added ‘tactility and feedback’ to the 2.0-litre F-Type’s steering but, again, it’s the R8 that offers the greater interaction. Its hydraulically assisted helm is heavier than the Jaguar’s EPAS but offers much more feel and, despite its weight handicap, the Audi also has tighter body control and responds more sharply.

The R8 devours corners with an aggression and level of grip beyond the ken of the F-Type, and there’s enjoyment to be had in that.

But the rear-driven Jag’s handling is more vivacious on our snaking test route, where its fine cornering balance can be urged into a playful shimmy of the tail where the Audi just pounds on ruthlessly. And here, the F-Type’s more pronounced body movements are no barrier to fun; in fact, managing the weight transfer is part of it. The Audi’s chassis is objectively more impressive, but the Jaguar’s is more amenable.

Given their agility, both cars ride well on 19in wheels, rounding off sharper bumps competently. They can jostle a bit on rougher surfaces but, providing you avoid ‘Sport’ on the Audi’s optional two-mode adaptive dampers, neither becomes disruptive.

The F-Type’s engine is quieter at a steady cruise, but the R8 incurs less road and wind noise; you could happily take on a long motorway slog in either.

And if that slog led home, it’s the Audi I’d choose. It has the haughtier chassis and fewer luxury touches than the genuinely competitive entry-level F-Type but, over the piece, the R8 offers its driver more stimulation, more of the time. It’s one of the used performance car bargains of our time.

JAGUAR'S GISTORY OF FOUR-POT PERFORMANCE CARS

The Ingenium engine in the F-Type is far from the first high-performance four-cylinder from Jaguar.

While the groundbreaking XK120 sports car employed sixpot power, there were once plans for a 2.0-litre alternative with two fewer cylinders, called the XK100. Like the 3.4-litre XK6 straight six, the four had an iron block but an aluminium head and pistons and was good for 105bhp, but the project was dropped due to poor refinement.

Installed in an MG-based ‘special’, a tuned version of the engine helped Lt Col Goldie Gardner break the 2.0-litre speed record in 1948 when he managed 176.7mph at Jabbeke in Belgium.
