Atom 4

Ariel Motor Company declares the launch of the newest evolution of the Ariel Atom, now in its fourth era, the all-new Atom 4.

Designed by the in-house Ariel group, the Atom 4 continues the now iconic design, but is an completely new automotive from the ground-up.  Building on the training from previous generations, customer feedback, Ariel assembly technicians and vital R&D by Ariel in recent times, the Atom 4 preserves the important Ariel qualities however progresses the design and engineering additional into probably the most highly effective and in a position Atom yet.

Atom 4 options the newest Honda Sort R turbo engine giving 320bhp as normal, all-new chassis, suspension, steering and brakes, all-new bodywork with vital aerodynamic improvements, new seating and instrumentation together with a number of design improvements and modifications.  With an open design temporary to improve the automotive wherever potential, the Atom four represents one other massive step forward within the evolution of the Atom.

Stated Simon Saunders, Director of Ariel: “The Atom 4 is the biggest change to the car since we originally released it in 1999.  It really is an all-new car; in fact there are only three parts carried over from the last Atom – the clutch/brake pedals and the fuel cap.”

Atom four will continue to be made in low volume by Ariel at its manufacturing unit near Crewkerne, Somerset in quantities of round 100 automobiles per yr alongside the Ariel Nomad and Ariel Ace motorcycle.

Every automotive will probably be built, as they’re now, by one technician and to order for every particular person buyer.  Having earned its status as the ‘Savile Row of the Automotive World’ Ariel has a tailored strategy to building automobiles that isn’t potential at high quantity and displays the alternatives achievable solely in low quantity manufacturing.  Atom 4 will even be made, beneath licence, by Ariel North America based mostly in South Boston, Virginia serving North and South American markets.  The automobiles could have equivalent specifications, combining one of the best excessive and low quantity engineering, supplies and manufacturing values together with an choice listing and bespoke build system that provides every customer exactly the automotive they want.  From fun sports activities automotive to track weapon, the Atom 4 will ship.

The automotive will even be the primary Ariel car to bear full European Small Collection Sort Approval  (ESSTA) and ADR (Australian Design Rules) testing, to allow Atom 4 to be bought all through Europe and Australasia with a Certificates of Conformity from 2019.  Stated Tom Siebert, Director of Ariel Motor Firm: ‘Though we have had a small European presence over the years, there is an enormous demand for our vehicles in this market and elsewhere in the world.  British-built, low volume vehicles appeal on many different levels and Type Approval is key to our future commitment to service those markets effectively.  As well as our existing network of dealers, we will appoint new key agents in various countries, to make sure that as many potential customers have access to Atom 4 as possible’.


As one of many very oldest names in automotive history, Ariel was started in 1870 by James Starley, also inventor of the differential and rack-and-pinion steering, with an Odd (Penny-Farthing) bicycle.  As the first steel-framed manufacturing bicycle, the Ariel additionally featured steering and patented spoked wheels, revolutionising the early transport business.  With the speedy improvement of automobiles in the 1890s and early 1900s, Ariel superior by way of De Dion-engined tricycles and Quadricycles in addition to motorcycles in a fast-changing business.  As a producer of early Grand Prix automobiles Ariel was an entrant in the first-ever race at Brooklands in 1907, profitable at the second occasion the following weekend.

From the late 1900s, the company centred its consideration on motorbike production with occasional excursions into four wheel automobiles.  Greatest recognized for the ground-breaking Ariel Square four, a number of Worldwide Six Day Trial profitable HT5 and pressed metal body Arrow, the corporate turned one of many great names of the British motorbike business.  Ariel was revived in 1999 with the launch of the Ariel Atom, featuring the now famous exposed spaceframe powered by a Rover Okay Collection engine.

A serious redesign in 2003 included the introduction of the Honda Okay20A Sort R engine and noticed the start of Ariel’s relationship with Honda, which continued into the Ariel Ace motorcycle and Ariel Nomad.  A continuing improvement of the automotive saw the Atom three launched in 2007, with the Honda Okay20Z Sort R engine, and the Atom three.5 in 2013 with revised chassis and suspension.  Over 1800 Ariel Atoms have been made because the first manufacturing automobiles have been delivered in 2000, making Atom possession an unique however rising club.  As a forward-thinking firm Ariel will proceed to evolve the Atom, however the soul of the Atom will all the time be attainable, rewarding efficiency and sheer driving pleasure.


The idea of Atom four is an all-new tubular chassis, designed in-house by the Ariel engineering and design staff, with a lot learning coming from the Titanium Chassis R&D undertaking of 2014.  Featuring larger diameter fundamental and diagonal tubes than earlier Atoms, in addition to many detailed additions, each tube inside the chassis has been analysed and optimised to offer a light-weight but extraordinarily robust structure.  The torsional stiffness has been elevated by 15% compared to the earlier era Atom 3.5.

The mixture of refined CAD (Pc Aided Design) and FEA (Finite Component Analysis) design work leading to a hand-made, bronze welded construction displays Ariel’s strategy to design and manufacture, combining new know-how with distinctive craftsmanship.

Stated Tom Ward, Ariel’s Chief Engineer: “Redesigning an icon can be quite intimidating and doing this with increasingly strict legislation plus Type Approval in mind is a big task for a small company like ours.  Our growing design and engineering team forms 25% of the Ariel workforce so we are committed to making Ariel absolute leaders in their field.”

The chassis provides more inside area and legroom than beforehand and has been designed and confirmed to properly exceed the demands of a full frontal 50kph barrier influence, seat belt and rear impression check.  Forming a driver/passenger safety cell the Atom chassis provides the very best degree of protection in its class. Chassis are handled to a three-stage ending means of phosphating, powder coating to color selection and powder coating lacquer.


On the coronary heart of the Atom 4 is the brand new Honda Sort R Okay20C 2.0L 4 cylinder direct injection, turbocharged engine. Constructing on the 15-year relationship with Honda UK with Honda power in Atom 2, Atom three and Ariel Ace motorcycles, Ariel has signed a brand new settlement for engine supply with Honda.  Stated Simon Saunders: “The Honda agreement is critical for us and our customers.  The Type R engines have proven themselves in Atoms over the years with dependable power and absolutely faultless reliability, even under race conditions, so there really is no better engine for the Atom.”

The 1996cc direct injection turbocharged engine, producing 320bhp as normal in the Atom – 10bhp greater than the previous supercharged Atom – provides the Atom four more power than any earlier commonplace mannequin.  An astonishing 420Nm of torque is an enormous 75% improve over a regular Atom three.5 and a 35% improve over a supercharged Atom three.5.

Mapped by Ariel utilizing an MBE ECU (Digital Control Unit) developed specifically for the automotive will permit the Atom 4 to satisfy Euro Vl emissions requirements, a essential issue of the EUSSTA testing.  Optionally available Launch and Traction Management is a brand new function inbuilt to the electronics of Atom four, derived from the Atom V8.  Atom 4 also options the power to adjust and optimise turbo increase levels for various street and monitor circumstances.

An all-new exhaust system, again designed to satisfy EUSSTA standards as well as race monitor noise levels, contains a ceramic honeycomb, excessive palladium/rhodium content catalytic converter, 3”/75mm diameter stainless system right into a twin outlet, eight.four”/215mm stainless silencer.  A excessive move single outlet system is an choice as is a de-cat system to be used on the monitor

A larger capability gasoline tank sits on the left-hand aspect of the automotive, enhancing range on street and on monitor, giving a street range of some 300 miles.

Suspension and Steering

Retaining the inboard, pushrod operated damper system the Atom 4 features all new suspension geometry.  Based mostly on 18 years of continuous improvement from Ariel and design enter from suspension guru Richard Hurdwell, the brand new geometry consists of revised inboard and outboard points plus anti-squat and anti-dive to scale back unnecessary body roll and weight transfer, retaining as a lot tyre contact as potential at all times.  All new Bilstein dampers sit inboard operated by pushrods by way of new geometry bellcranks, with an elective semi-active Ohlins package deal beneath improvement for manufacturing.

Revised steering rack and geometry give the new Atom accessibility for every type of drivers beneath all driving circumstances, with the choice of a fast rack for track-focussed automobiles. “It’s important that the Atom not only handles superbly but has ultimate driveability,” stated Sam Evans, engineer in control of Atom suspension improvement. “On Atom 4 we have gone to enormous lengths to ensure the car is as easy to drive on the road as it is fast on a race track.”

An improved turning circle has additionally been achieved with the new suspension and steering rack geometry to assist town driving and parking.

Wheels and Tyres

Shifting up in measurement the Atom four sits on 7Jx16” front wheels and 9Jx17” rear wheels.  Multi-spoke alloy wheels are normal fitment however, in a primary for Ariel, the Atom four has the choice of full carbon wheels.  These symbolize a weight saving of almost 50% over an alloy wheel and a complete discount of over 16 kilos. The wheels, made to Ariel specification by BST in Johannesburg (who also make the carbon wheels for the Ariel Ace), significantly scale back unsprung weight collectively with new aluminium uprights, which alone give a 50% weight saving over the previous automotive.

Tyres are 195/50R16 front and 255/40ZR17 rear. In a new exclusive partnership with Avon Tyres the Atom will probably be fitted with excessive performance Avon ZZR tyres.  With current modifications in tyre regulation and noise it will be important that the very best performing tyres can be found to the Atom.  The mixture of latest suspension and bigger section Avon tyres contribute to the Atom 4 having extra mechanical grip than any earlier Atom.  Not only is straight line performance improved for the Atom four but cornering velocity moves to a different degree additionally.


The all-new commonplace braking system increases in measurement, because of the larger power of Atom four, with 278mm vented discs and forged two-piston caliper on the front with 253mm discs on the rear and built-in hand brake caliper.   An optionally available upgrade is to a full AP Racing configuration of 290mm vented discs front and rear with alloy 4 piston calipers.  Quite a lot of brake pads can be found dependent on using the automotive.  An all-aluminium pedal field with brake, clutch and throttle pedal is supplemented by the optionally available cockpit adjustable brake bias. Goodridge stainless hose for both brake and clutch hydraulic techniques is commonplace fitment.


The Atom four options an all-new look and whereas recognisably an Atom, each panel on the automotive is new.  One of many elementary design rules on Atom four was aerodynamic enchancment, control of airflow and general stability of the automotive.  Working in partnership with TotalSim, CFD (Computational Fluid Dynamics) specialists in Brackley, and in protecting with the original Ariel ‘Form Follows Function’ philosophy, major aerodynamic improvements have been made in each space of the automotive.  Drag has been lowered, downforce elevated and mass stream price to radiator, intercooler and air intakes drastically increased.  A shift in aero-balance has been achieved to offer neutral handling and extra precise control at the limit.

Instantly noticeable is the disappearance of the acquainted central Atom roll hoop, now enclosed underneath the air consumption bodywork, which itself has been gotten smaller. This has tremendously improved air passing over the rear bodywork and controls air velocity going by means of the ram-air system. Equally, the brand new nose cone has smaller openings and inner ducting to scale back drag and decelerate air velocity, maximising effectivity by means of the front mounted radiator.  The intercooler mounted behind the tub, in a low strain space, keeps the unit close to the engine and can also be provided with air from underneath the automotive, optimising cooling efficiency.

The trademark Atom ‘aero screen’ has been additional refined and now reaches all the best way across the automotive, decreasing ‘helmet lift’ for the occupants, directing air to the engine consumption and, with simply this aero fence, generating 100 Newtons of downforce.  The mudguards on all four wheels also function an aero gadget to offer downforce on to tyres negating any carry from mudguards.

Ralph Tayler-Webb, Chief Designer at Ariel stated: “The aerodynamics on the Atom 4 have been an epic journey with literally hundreds, if not thousands, of iterations backwards and forwards between us and TotalSim.  Keeping the Atom true to its roots but making such big strides with the aero has been a long haul, but it has paid off.  Atom 4 is a highly-sophisticated design that has improved the performance in many different ways and on a number of levels.”

Bodywork can be obtainable in full carbon for most of the body elements, reinforcing the ‘Less = More’ Ariel philosophy of performance via light-weight.

Exterior and Inside

All exterior lighting has been revised with LED indicators, cease/tail/fog and reverse lights, daytime operating lamps and high efficiency halogen headlights to evolve to EUSSTA laws.  Ambient mild sensors permit auto mild functionality.

Further space for storing has been included beneath the removable entrance body cowl, extending the cubby field, together with entry to the brand new hydraulic system. Individually adjustable single seats exchange the dual seat unit of previous Atoms and a comprehensive research into ergonomics has subtly repositioned pedals, steering wheel and instruments.  Already a cushty area for most drivers, an further 50mm of cabin length and 20mm width has been added to accommodate the very widest vary of users.

The brand new change cluster, once more designed to EUSSTA requirements, options all controls inside finger attain of the 310mm suede steering wheel together with lighting, indicators, adjustable traction and launch controls.  The central devices, with full colour TFT (Thin-Film-Transistor) display made for the Atom four by AIM, could be scrolled via a number of menus for street, monitor or set up use. The devices also have gear position and shift lights as commonplace plus provision for actual time race monitor data-logging.  Utilizing the AIM PDM (Energy Distribution Management) system, communicating instantly with the ECU by way of CAN (Controller Space Network), the car wiring harness and fuse box have been simplified and subsequently light-weighted.

Performance and Worth

Atom 4 is the quickest normal Atom produced up to now. With the dramatic improve in torque, as well as 320bhp as commonplace, each standing begin and in gear acceleration occasions are the fastest yet for a standard Atom: 0-60mph in 2.eight seconds, Zero-100mph in 6.eight seconds retain the Atom’s big killing efficiency.

Atom 4 shall be priced at £39,975 together with VAT in the UK (£33,312.50 ex VAT).   Stated Tom Siebert: “We need to maintain the Atom as an reasonably priced but final efficiency automotive.  The price of the Atom 4 compares with a supercharged Atom three.5, however it has extra power and a better specification as normal.  Over the 18 years that we have now been making the Atom it has proved itself with terribly low operating costs and phenomenal reliability, even when used arduous on monitor.

“This coupled with truly remarkable residuals makes the Atom not only cost effective to own but almost depreciation free. But our main aim for our customers is our company motto – SERIOUS FUN. There isn’t enough of that in motoring any more, so we’re determined to keep it. If that’s what you want, Atom 4 will deliver.”

Atom 4 production will begin in late 2018, for Spring 2019 deliveries.
