PH samples Ariel's updated Atom 3.5 - it's more awesome than ever

Weíll set the record straight at the start. 3.5 doesnít refer to another ridiculously over-engined Atom akin to the firmís scary V8 - but rather a package of updates that sees the Atom 3 evolve into a fitter and more useable sports car. No, seriouslyÖ

LCD dash is new and will log data
LCD dash is new and will log data
That means the looks are tweaked, thereís a new LCD dash that will log your data on track and show what gear youíre in, some geometry changes that alter the steering Ė making it more forgiving on-road, without losing any of that track focus Ė and more bracing around the new engine and rear suspension mounts, meaning the Ďpoint-fiveí is 15 per cent stiffer torsionally than the 3.

Donít be soft
As I cruise along the A303 from Arielís Somerset base to meet snapper Tom near Stonehenge Iím watching the Atomís nearside front wheel track the surface through the chassisí exposed lattice work Ė the carís reaction to the image Iím seeing doesnít compute.

The wheel spikes up and down but the compliance in the dampers filters out any harshness. Granted, catís eyes can still give a clonk and grids can initiate a minute waggle from the rear (most likely to do with setup), but the plush feeling from each corner of the car on normal roads at normal speeds is accomplished to the point of being incongruous given the Atomís hardcore focus.

Donít think this has made the car soft though Ė itís still bristling with all the pent up aggression of a caged ferret.

Supercharged VTEC gains 10hp
Supercharged VTEC gains 10hp
The 3.5 uses the same supercharged 2.0-litre Honda VTEC motor as before, but the new car gets a 10hp boost to 310hp, courtesy of alterations to the mapping, plumping up the mid-range. It didnít need it, but itís got it. The engineís ferocious, and the 229lb ft of forced induction torque means instant acceleration in any gear thatíd embarrass a 911 owner. Itís here the gear display comes into its own too, as in third, fourth and fifth the motor produces a seemingly similar horizon-smashing bout of acceleration.

Throttle response is immediate, despite being fly-by-wire; what you ask for is exactly what you get. The engine has a massive appetite for revs and itís easy to run into the staccato pap-pap of the 8,600rpm limiter. The six-speed manual Honda Ďbox just adds to the feeling of relentless pace, too Ė each manual change snicked punctuates the onslaught and involves more than a paddle shift transmission ever could.

If youíre after the stats 0-60mph comes up in 2.7 seconds, 100mph in a superbike troubling 6.8 and top speed stands at 155mph. Believe those numbers Ė it simply atomises the road.

Atom retains customary agility

Accuracy assured
The steering changes havenít stripped the 520kg Atom of any of its agility. The 3.5 gets more toe out to help turn-in, and combined with 1.7 turns from lock-to-lock it means the steering is fast, accurate and stable.

Thereís understeer on turn-in and you can feel the comparatively light front end smudge the tyres across the Tarmac. Trail the brake on corner entry to keep weight over the front and you can coax the nose, then pick the throttle up and reverse the balance Ė making the Atomís natural weight distribution key the rear rubber into the road Ė and youíll be fired out the other side.

It sounds technical but itís intuitive; you just do it. The 290mm four-pot Alcon brakes all-round give a reassuringly solid feel and inspire confidence to brake late and deep despite lacking ABS.

Slides are manageable, but rare
Slides are manageable, but rare
If it does slip into a slide itís manageable, but even on slick, greasy roads and lightly treaded Yokohamas thereís plenty of grip. Get them hot on a dry track and not much this side of a slick-shod and wing-wearing racer will come past you all day.

Road and/or track
I played around with the suspension damping all day but returned to Ariel General Manager Tom Siebertís settings. For the road theyíre spot on and tread the perfect line between tautness, control and compliance.

You canít exactly call it practical but the Atom 3.5 is a better road car for the changes, without losing any of its single-minded focus to go faster and harder than whatever itís placed against.

Obedient on the cruise and with a motor thatís happy to pootle around at low revs the Atom 3.5 is as docile as you like, making a great car even greater Ė thatís because it hasnít lost its rabid character at the other end of the spectrum. Stoke it and it turns into the same unhinged piece of weaponry itís always been.
