There are some cars which have the power to completely captivate all of those around them just by their mere presence. No sound. No fanfare. Car people just know when there’s something special around. Heads turn, a crowd gathers. Jaws hang open. I know of few cars that have this power more than the astonishing Napier-Railton, a car which is 80 years old. I think this is one of the most beautiful, imposing cars ever made. And then you hear the 24-litre aero engine running: grown men weep, children gasp, angels sing. The aero engine at the heart of the Napier-Railton is the sound of a thousand storms. It’s the sound of… victory.
I defy anyone to witness this car in the flesh and dismiss it as an irrelevant automotive anachronism. So it’s positively medieval in the technology it uses. So it’s not the product of some fashionable tuning house (though actually in period it was…). It’s not a well-known name. It’s old; most likely far older than anyone reading this.
But just look at the next picture and I think you’ll understand.
Four wheels off the ground at the Brooklands oval as the car hits the bump on the bridge over the River Wey and already pulling over 130mph, John Cobb hangs on to his two-ton leviathan as he approaches the Railway Straight, where the car will accelerate to almost 170mph.
Just 17 drivers lapped the 2.8-mile Brooklands oval at more than 130mph, earning one of the circuit’s coveted 130mph badges. Cobb went even further, setting the fastest ever lap of the banked Outer Circuit in the Napier-Railton at an average speed of 143.44mph in 1935. It’s a record that will never be beaten: here we have a car that has outlasted the track it became so famous on.
The Napier-Railton is everything you could ever want in an automobile, as long as it’s not comfort, a CD player or a bad body kit. It was an endurance racer. A dragster. A Time Attack specialist. A Land Speed Record holder. And it won everything. Built over the winter of 1932 the Napier-Railton quickly became recognised as the ultimate Brooklands racing car, the most historic and revered racer in the circuit’s 32 year history and the perfect encapsulation of the spirit of that era.
The car is intimidatingly large at almost five metres long and has a wheelbase over three metres, but has a streamlined body, raked and curvaceous, that belies its age and sets the car apart from the more angular, upright contemporaries. Sheer power and speed look like they’ve melted the Napier-Railton and raked the whole thing backwards, accentuating the impression of speed even when it’s standing still. Like any good modern car in fact. This is the Bugatti Veyron of its day.
Contrary to the suggestion given by its size and weight, this was a well-developed, advanced racing car. It steered easily and was tractable to drive; braking was good, despite the limitations of the drums. Even people who are lucky enough to drive the Napier-Railton today comment on how docile the car is: almost impossible to stall with its galaxy of torque, and voluptuous in turns.
The architect of the Napier-Railton was John Rhodes Cobb, Brooklands’ ‘Gentle Giant’, who had lived near Brooklands as a teenager and cycled down there to watch the racing. After making his career as a successful fur-broker he had the funds to pursue his childhood passion, and in 1925 drove a 10-litre FIAT to victory – in his first ever race. He subsequently raced Parry Thomas’ famous 27-litre ‘Babs’ Special, before buying a V12 Delage in 1928. Wins became the norm, but as the years went on the competitors raised the bar – and none more so than ‘Tim’ Birkin.
Sir Henry ‘Tim’ Birkin had raised the Brooklands lap record to a 137mph average in his Blower Bentley, out of the reach of Cobb’s Delage. With his sights set on that speed and also on taking the World 24 Hour record, Cobb commissioned Reid Railton to design him a new car, with money no object.
From Railton’s pen flowed the Napier-Railton, and Brooklands-based manufacturing specialists Thomson & Taylor were engaged to build it. T&T had fabricated Malcolm Campbell’s Bluebird Land Speed Record machines, and were also Alfa and Railton maintenance specialists.
Enormous capacity aero-engined racers had dominated the record books at Brooklands after the First World War, so the the chosen powerplant was a Napier Lion Type E89 Series XIA 12-cylinder ‘broad-arrow’ aero engine. The design dated from 1919, but was chosen for its power and rugged reliability – it was based on a unit used by the Royal Air Force in the ’20s.
Despite its huge displacement of 24 litres, the aluminium block and cast head are relatively compact and allowed the bare aluminium body to be far lower than the previous generation of aero-engined monsters – almost streamlined in fact.
The engine was in a W12 configuration, with three banks of four cylinders. The outer banks are installed at 60 degrees to the central bank, which resulted in the elaborate triple exhaust system. Double overhead camshafts connect to each bank, with four valves and two spark plugs per cylinder.
Stock, the engine would produce 502bhp, but Cobb had his unit modified and on the test bench it was able to develop 564hp. As with all racers of the time, the block was front longitudinally mounted. The cavernous capacity is matched to a disarmingly low rev limit of just 3,000rpm, meaning there are acres of torque: 1,184lb ft is estimated, with the optimum power of 530bhp delivered at around 2,500rpm.
A pair of thick leather straps keep the big vented bonnet panels in place.
Ignition is provided by twin Watts magnetos, controlled by, of all things, basically a light-switch housing. Getting the engine turning over was something even more simple: pushing. This meant – and still means – that getting the Napier-Railton firing requires several mechanics putting their backs against the two-tonne machine.
Once rolling, the rear wheels are driven through a bespoke Moss three-speed crash gearbox with no reverse, cantilever mounted, running through a Borg & Beck single-plate dry clutch.
To keep the beast of an engine running requires a whole lot of fluid. The Napier-Railton originally mounted a 65-gallon petrol tank that took 10 minutes to fill.
Oil tank capacity is 15 gallons (the engine itself utilised dry sump lubrication) of Castrol GP50 and the cooling system requires 12 gallons of 25 percent Bluecol antifreeze solution.
The bonnet has several caps dotted over it for the various filler tanks, which are themselves little pieces of metalwork art.
Wooden rods are stored in the cockpit for checking petrol and oil levels.
These are simply retracted out of their brackets and dipped into the relevant tanks, using the marked scale as a measure.
By the time the Napier-Railton was being designed, the rigours of racing around Brooklands were well known: the new car would be based on a heavy duty ladder chassis with a pair of underslung live axles, and variable-rate hydraulic dampers at the rear adjustable from the cockpit. Twin cantilever leaf springs sat outboard either side at the rear, delivering a meaty four-bar set-up necessary to cope with Brooklands’ notorious bumps.
The front springs were semi-elliptical with outboard friction dampers, which were also installed inboard the rear. The mechanicals are extremely sturdy, which was absolutely required for the extreme operating conditions of the car, but at the same time have a beautiful, sculptural quality.
It’s the same all around the suspension parts of the car: it’s like an exhibition of Steam Punk flourishes…
…matched with hardcore post-Victorian industrial design.
Andre Hartford Shock Absorbers were de rigueur at the time, an early form of damper. They worked by the friction created from the stack of disks inside the unit held together by a spring and bolt – an external dial showed the approximate setting in use.
As we’ve already seen, keeping in contact with the track was always a major issue, despite the damping. On the odd occasion when there was rubber on concrete, it was through bespoke tyres developed by Dunlop; treadless rubber in various sizes for 20×7.5-inch to 35×6-inch sizes were used, depending on conditions and the type of event. The car currently runs on modern Blockley rubber: 21×6.75/7. Blockley was founded about a decade ago by historics racer Julian Mazjub specifically to create authentic rubber for pre-war cars.
The cockpit was a hostile place. Refined, comfortable, calm – none of these words would be appropriate. The Napier-Railton would reach a top speed of 168mph down the Railway Straight. Cobb would be precariously perched in the car – maybe ‘on’ would be more appropriate, although with the fared bodywork around the cockpit and small air-deflecting windscreen he was more embedded in the car than most of his competitors in theirs. On driving around Brooklands, he said it was like “Seeing how far one can lean out of a window without falling out, and therefore somewhat risky”. That’s some understatement, especially in mind of the open side of the car, lack of belts and armchair of a seat.
Getting up to nearly 170mph was one thing – stopping was another. Thankfully, for the most part, where Cobb was going he wouldn’t need front brakes. 16″ drums were originally fitted to the rears only, controlled by a foot brake, with a hand brake connected directly to the transmission via expanding shoes in a drum behind the gearbox.
As soon as the car drove out of the Brooklands workshop in 1933 it was clear that it was something special – as long as Dunlop could produce the requisite rubber that could withstand the forces. In the Napier-Railton’s first event in August 1933, Cobb set a new standing start lap record of 120.59mph and a flying lap of 123.28mph, winning the race by 2.6 seconds. His next outing took the speed to 137.2mph, a new Class A record. Cobb took the car to the Montlhéry oval near Paris for his first attempt on the 24 Hour record: tyre trouble interrupted that run, but he still broke the 200-mile speed record (126.44mph average) and a multitude of other lower distance records.
In 1934 the Napier-Railton returned to Monthlhéry: this time Cobb’s run was ruined by the small matter of the Napier going over the edge of the banking… But back in one piece and back at Brooklands Cobb clocked up 143.67mph in the Class A standing-start mile record and upped the lap record once again, taking the lap record from Birkin after setting a 139.71mph lap. Next was a trip to the Utah Salt Flats in 1935: the Napier-Railton took the World 24 Hour record and for good measure also took every other record between one and 23 hours.
Returning home again, Cobb won the 500 mile race, setting a new speed record of 121.28mph in the process which remained the fastest average speed for a 500 mile race until the 1949 Indianapolis 500. He then set his Napier-Railton to crushing every other record at the track: fastest short and fastest long distance races; fastest standing start lap of 120.59mph… But the Outer Circuit lap was still the ultimate target, and four times he upped the average speed.
On the 7th October 1935 Cobb made another speed run on a damp track: his Dunlop tyres lasted only two laps, but he somehow set a lap of 143.44mph, with a top speed of 151.97mph showing the Napier’s barely abated speed despite the treacherous conditions. It was a lap that would never be beaten.
Contemporary video is naturally scarce, but this clip gives some context to what that speed meant: Brooklands was insanely bumpy even when new, with no barriers and a hilariously dangerous mismatch of car sizes competing against each other. And we worry about prototypes and GT cars nowadays…
The Napier-Railton wouldn’t go faster at Brooklands, but in 1936 it returned to Bonneville and maintained a 168.59mph average over a 100 mile run. The following year Cobb gave the Napier its last race outing at Brooklands in the final 500 run there and won, before turning his attention to the Land Speed Record. He would become the fastest man on earth in 1939 when he shattered the LSR in his Brooklands-built Railton-Special, reaching 326.7mph at Bonneville, and in 1947 he went faster still, hitting 398.82mph
But the Napier-Railton lived on: its fame meant that it was still a darling for the public, and it appeared on film even as late as 1949 in the Ava Gardner film Pandora And The Flying Dutchman. After Cobb’s death in 1952 during an attempt on the World Water Speed Record at Loch Ness, the Napier-Railton was sold on and used to test aircraft braking parachutes at Dunsfold aerodrome for the RAF in the 1950s: Dunlop callipered disk brakes were fitted to the rear wheels, which it still has now.
After its military service ended the Napier-Railton returned to private hands and was again raced in the 1950s, but displayed at the National Motor Museum in Beaulieu in-between times. During a restoration in the 1970s it was confirmed that it had the same original engine from 1933; it was sold twice more in the ’80s (owners included the chairman of Aston Martin) and ended up in Germany, before being restored again in 1997 and loaned to the Brooklands Museum and run at the Goodwood Festival Of Speed.
In 1998 it was offered to the Museum and purchased with help from a group of benefactors that included Rowan Atkinson, Ron Dennis, The Earl Of March and Tom Walkinshaw, and since then the Napier-Railton has been at home. Where it belongs. It’s still regularly run out, both at Brooklands and at events round the UK, and continues to draw admiration and love from all who see it. It’s a magical car: a living, relevant piece of automotive history.

Just saw this, with a police escort, leading a host of classic cars down The Mall in front of Buckingham Palace. Wonderful sight.
This car reminds me of the Silver Arrow D-type from Auto Union (http://www.youtube.com/watch?feature=player_embedded&v=Hsz84DZsyCg#!). Also a speed monster http://automotive.lilithezine.com/Audi-R8-Auto-Union.html. But I wouldn´t dare compare these two in any sort of way. The Napier Railton car is in a class of its own. A true icon. By the way, I love your site. I am for the most part a motorcycle fan and I live far, far away from U.S. and Bonneville, but now after checking this site out, I will make it my one true purpose in life to visit Bonneville Speed Week at least once.
this car is incredible!! i wish i was around to see it in its prime! just puts a smile on my face whenever i saw a picture...i miss these old beasts, they should make modern ones using aircraft engines!!
You always give us information in detail. Thanks for the information.
Hands down the best article on Speedhunters! Well done Mr Moore, top class stuff indeed. Thanks very much for sharing this amazing car with us in such detail, I could not stop reading till I got to the end...
Brilliant article about an amazing car.
It's too young and powered internal combustion to be steam punk though, Diesel punk definitely!
one of the BEST SpeedHunter drops yet! writing, pictures, history, all top notch! i love seeing, hearing, and reading about classic racers and endurance cars of the past. these cars and the men who drove them were Extraordinary. akin to dragons and dragon tamers.
can you imagine?! 165+ mph with no seatbelts no safety equipment, with a fire spitting (often literally) ultra large displacement monster yanking you along under the hood; and on skinny bias-ply tires no less, and pathetic brakes! those guys had balls of steel!
I remember my Dad taking me to the Brooklands museum when I was younger, purely to see this car. Absolute madness on wheels, love it! Great article Jonathan.
Grown men weep. Damn right because its beautiful . Also they were probably weeping at the cost of filling this bad boy up. 65 gallons ouch! i see the price of speed has always been expensive. This car had alot of tech to. The one thing that i find funny is that these cars were metal masterpieces but the hoods are held down by waist belts. The cows must have been tougher too back in the day.LOL. This is another Great Article.
Only on Speedhunters will you find TAS 2013 coverage back-to-back with a full feature on an 80-year old racer. Thanks, SH.
2 things, WTF!!! Did that say this car 398mph? That must of been scary! And isnt dunsfold aerodrome where they now film top gear? Great feature by the way!
This has to be one of the coolest story (of many cool ones) that I've ever read on this site! Thanks for the history lesson!
Everything about this car is awesome, the photos are great, and most of the article is well written. But please don't call a masterpiece of historic automobiles 'steampunk' as if it's part of some cheap 21st century sci-fi genre popularized at comic conventions! For shame.
I'm still a fan of Brutus, but this is a badass car. I never really read or see too much information about these crazy cars and the even crazier drivers, it's cool to see a whole story about one. And that video, some of those cars that were being passed looked like toys compared to (this?) or similar vehicles. Either way, awesome.
Oh wow. That must have been quite a sight: cabs, buses... and the Napier-Railton! I wish I'd seen it!
@judymboroki Why are you advertising tow hitches on here? Go away.
@roeby Ah no, Cobb had a dedicated LSR car built which was like a UFO, also designed by Reid Railton. And yes, Dunsfold is home to Top Gear!
@inspector_exacto Yea they were fearless but i think anyone of us car guys if we were in that era would have jumped in that without thinking twice. I know i would.
@inspector_exacto They really were – the stories from that era are incredible. Such fearless nonchalance... But then, after WWI an almost medieval attitude to life seems to have taken hold.
It's like its being called something, when that something was an artistic imitation of this beast. Oh the irony! Maybe you're trying to appeal to a younger demographic by using modern slang, but trust us, this stands apart, no need to pander.
As a side note, this is my favorite feature in quite a while.
@AceAndrew2 @gliebau Often it's a case that a title using a slang term will get more interest, guys like yourself obviously appreciate just what this is. Sometimes to draw a new audience in to the subject matter, you often have to offer something which can be related too first. I simply love the thing :)
