Ariel Motor Company broadcasts 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 totally new automotive from the ground-up. Constructing on the training from previous generations, buyer feedback, Ariel assembly technicians and vital R&D by Ariel in recent times, the Atom 4 preserves the essential Ariel qualities however progresses the design and engineering additional into probably the most powerful and in a position Atom but.
Atom 4 features 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 enhancements and modifications. With an open design temporary to enhance the automotive wherever attainable, the Atom 4 represents one other massive step ahead in 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 4 will proceed to be made in low quantity 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.
Each automotive will probably be built, as they’re now, by one technician and to order for each particular person customer. Having earned its fame as the ‘Savile Row of the Automotive World’ Ariel has a tailored strategy to building automobiles that isn’t attainable at excessive quantity and displays the opportunities achievable only in low quantity production. Atom 4 may also be made, beneath licence, by Ariel North America based mostly in South Boston, Virginia serving North and South American markets. The automobiles may have equivalent specifications, combining one of the best excessive and low quantity engineering, supplies and production values together with an choice listing and bespoke construct system that provides each customer precisely the automotive they need. From fun sports activities automotive to track weapon, the Atom 4 will ship.
The automotive will even be the first 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 Certificate 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 historical past, Ariel was began in 1870 by James Starley, also inventor of the differential and rack-and-pinion steering, with an Unusual (Penny-Farthing) bicycle. As the first steel-framed production 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 advanced by means 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 on the second event the following weekend. From the late 1900s, the company centred its consideration on motorbike manufacturing with occasional excursions into 4 wheel automobiles. Greatest recognized for the ground-breaking Ariel Square 4, multiple International Six Day Trial profitable HT5 and pressed steel frame Arrow, the company turned one of the great names of the British motorbike business. Ariel was revived in 1999 with the launch of the Ariel Atom, that includes the now well-known uncovered spaceframe powered by a Rover Okay Collection engine. A serious redesign in 2003 included the introduction of the Honda Okay20A Sort R engine and saw the start of Ariel’s relationship with Honda, which continued into the Ariel Ace motorcycle and Ariel Nomad. A continuing improvement of the automotive noticed the Atom three launched in 2007, with the Honda Okay20Z Sort R engine, and the Atom 3.5 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 ownership an exclusive but rising membership. 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 4 is an all-new tubular chassis, designed in-house by the Ariel engineering and design workforce, with a lot studying coming from the Titanium Chassis R&D challenge of 2014. Featuring larger diameter foremost and diagonal tubes than previous Atoms, as well as many detailed additions, every tube inside the chassis has been analysed and optimised to provide a light-weight but extraordinarily robust construction. 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 Aspect Analysis) design work leading to a hand-made, bronze welded construction displays Ariel’s strategy to design and manufacture, combining new know-how with exceptional 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 previously and has been designed and proven to nicely exceed the calls for of a full frontal 50kph barrier influence, seat belt and rear influence check. Forming a driver/passenger security cell the Atom chassis presents the very best diploma of protection in its class. Chassis are handled to a three-stage finishing means of phosphating, powder coating to colour selection and powder coating lacquer.
At the heart of the Atom 4 is the brand new Honda Sort R Okay20C 2.0L 4 cylinder direct injection, turbocharged engine. Building on the 15-year relationship with Honda UK with Honda energy in Atom 2, Atom three and Ariel Ace motorcycles, Ariel has signed a brand new agreement 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 earlier supercharged Atom – provides the Atom 4 extra energy than any previous normal model. An astonishing 420Nm of torque is an enormous 75% improve over a regular Atom three.5 and a 35% improve over a supercharged Atom 3.5.
Mapped by Ariel utilizing an MBE ECU (Electronic Control Unit) developed specifically for the automotive will permit the Atom 4 to satisfy Euro Vl emissions requirements, a essential factor of the EUSSTA testing. Non-compulsory Launch and Traction Management is a new function inbuilt to the electronics of Atom 4, derived from the Atom V8. Atom 4 also features the power to regulate and optimise turbo increase ranges for various street and monitor circumstances.
An all-new exhaust system, once more designed to satisfy EUSSTA requirements in addition to race monitor noise ranges, includes a ceramic honeycomb, high palladium/rhodium content catalytic converter, 3”/75mm diameter stainless system right into a twin outlet, eight.4”/215mm stainless silencer. A excessive movement single outlet system is an choice as is a de-cat system to be used on the monitor.
A bigger capability gasoline tank sits on the left-hand aspect of the automotive, enhancing vary 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 options all new suspension geometry. Based mostly on 18 years of continual improvement from Ariel and design enter from suspension guru Richard Hurdwell, the new geometry consists of revised inboard and outboard points plus anti-squat and anti-dive to scale back pointless body roll and weight transfer, preserving as a lot tyre contact as attainable 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 underneath improvement for manufacturing.
Revised steering rack and geometry give the brand new Atom accessibility for every type of drivers beneath all driving circumstances, with the choice of a quick 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 brand new suspension and steering rack geometry to assist town driving and parking.
Wheels and Tyres
Shifting up in measurement the Atom 4 sits on 7Jx16” entrance wheels and 9Jx17” rear wheels. Multi-spoke alloy wheels are commonplace fitment however, in a primary for Ariel, the Atom 4 has the choice of full carbon wheels. These characterize 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 additionally make the carbon wheels for the Ariel Ace), considerably scale back unsprung weight together with new aluminium uprights, which alone give a 50% weight saving over the previous automotive.
Tyres are 195/50R16 entrance and 255/40ZR17 rear. In a new unique partnership with Avon Tyres the Atom will probably be fitted with high performance Avon ZZR tyres. With current modifications in tyre regulation and noise it will be significant that the very best performing tyres can be found to the Atom. The mixture of latest suspension and larger section Avon tyres contribute to the Atom 4 having extra mechanical grip than any earlier Atom. Not only is straight line efficiency improved for the Atom 4 but cornering velocity strikes to a different degree additionally.
The all-new commonplace braking system will increase in measurement, because of the larger energy of Atom 4, with 278mm vented discs and forged two-piston caliper on the entrance with 253mm discs on the rear and built-in hand brake caliper. An elective improve 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 are available depending 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 normal fitment.
The Atom 4 options an all-new look and while recognisably an Atom, every panel on the automotive is new. One of many elementary design rules on Atom 4 was aerodynamic enchancment, management of airflow and general stability of the automotive. Working in partnership with TotalSim, CFD (Computational Fluid Dynamics) specialists in Brackley, and in line with the original Ariel ‘Form Follows Function’ philosophy, major aerodynamic improvements have been made in each area of the automotive. Drag has been decreased, downforce elevated and mass stream fee to radiator, intercooler and air intakes tremendously elevated. A shift in aero-balance has been achieved to provide impartial dealing with and more exact control on the restrict.
Instantly noticeable is the disappearance of the acquainted central Atom roll hoop, now enclosed underneath the air consumption bodywork, which itself has been contracted. This has drastically improved air passing over the rear bodywork and controls air velocity going by way of the ram-air system. Similarly, the brand new nose cone has smaller openings and inner ducting to scale back drag and decelerate air velocity, maximising efficiency by means of the entrance 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 effectivity.
The trademark Atom ‘aero screen’ has been further refined and now reaches all the best way throughout the automotive, decreasing ‘helmet lift’ for the occupants, directing air to the engine intake and, with simply this aero fence, generating 100 Newtons of downforce. The mudguards on all four wheels additionally function an aero system to provide 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 will probably be obtainable in full carbon for most of the body elements, reinforcing the ‘Less = More’ Ariel philosophy of performance by means of lightweight.
Exterior and Interior
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 performance.
Further space for storing has been included underneath the removable entrance physique cover, extending the cubby box, together with entry to the brand new hydraulic system. Individually adjustable single seats exchange the twin seat unit of earlier Atoms and a complete research into ergonomics has subtly repositioned pedals, steering wheel and instruments. Already a cushty area for many drivers, an further 50mm of cabin length and 20mm width has been added to accommodate the very widest range of users.
The brand new change cluster, again designed to EUSSTA requirements, options all controls within finger attain of the 310mm suede steering wheel together with lighting, indicators, adjustable traction and launch controls. The central instruments, with full color TFT (Skinny-Film-Transistor) display made for the Atom 4 by AIM, might be scrolled by way of a number of menus for street, monitor or set up use. The devices even have gear place and shift lights as commonplace plus provision for actual time race monitor data-logging. Utilizing the AIM PDM (Energy Distribution Administration) system, speaking 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.
Efficiency 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, both standing start and in gear acceleration occasions are the quickest but for a standard Atom: Zero-60mph in 2.8 seconds, Zero-100mph in 6.8 seconds retain the Atom’s big killing efficiency.
Atom 4 can be priced at £39,975 including VAT within the UK (£33,312.50 ex VAT). Stated Tom Siebert: “We need to hold the Atom as an reasonably priced but ultimate efficiency automotive. The price of the Atom 4 compares with a supercharged Atom 3.5, however it has more energy and a better specification as normal. Over the 18 years that we’ve been making the Atom it has proved itself with extraordinarily low operating costs and phenomenal reliability, even when used onerous 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.
