The wall

  • Car poster sizes, and how to pick one.

    Five poster sizes, from A4 to 70 by 100 centimetres. The right one depends on the wall and the viewing distance rather than on the picture, and it is the decision people most often get…

  • How to frame a car print.

    A frame is not decoration, it is a decision about how much attention the picture gets. The good news with car art is that the artwork's own ground colour makes most of the choice for…

  • The wall

    Size, frame and room. What each format does to the same picture, and which one the wall in question actually wants.

The gift

  • They already bought it, in the spec they wanted.

    A serious enthusiast is genuinely difficult to buy for, and not because the shops are empty. It's because everything a shop sells for this hobby is a tool or a consumable, and they've…

  • In December, timing is the hard part.

    Choosing a car gift is a solved problem the rest of the year. In December the thing that actually goes wrong is the calendar, because nothing here exists until somebody orders it and the…

  • The gift

    Buying it for somebody else: what a car obsessive already owns, and what they do not.

The car

  • How many cars from each year are still licensed?

    The DVLA publishes the licensed car fleet by year of first registration. As of the end of December 2025, 13,785 cars first registered in 1973 still hold a licence - and 245 from 1923.…

  • Car questions, answered.

    Straight answers to the car questions people actually type into a search bar. Where a term has a real engineering definition, you get it with the source it came from. Where it does not,…

  • What is horsepower?

    Horsepower is a unit of power, meaning a measure of how fast work is done. One horsepower is 550 foot-pounds per second, which is about 745.7 watts.

  • What does BHP mean?

    BHP stands for brake horsepower: power measured at the engine's own crankshaft, before the gearbox, driveshafts and tyres take their share of it.

  • What is torque in a car?

    Torque is turning force. In a car it is the twisting effort the engine makes at its crankshaft, quoted in pound-feet in the UK or newton-metres elsewhere.

  • What is the difference between torque and horsepower?

    Torque is a force that twists. Horsepower is a rate at which work gets done. Engine speed is what connects them, and it is why the two peak at different points.

  • What does 0-60 mph mean?

    0-60 mph is the number of seconds a car takes to reach sixty miles an hour from a standing start. It is a stopwatch figure, not a certified one.

  • What is engine displacement?

    Displacement is the total volume all of an engine's pistons sweep through in one stroke, quoted in litres or cubic centimetres. It is a measure of size.

  • How does a turbocharger work?

    A turbocharger puts a turbine in the exhaust stream and bolts it to a compressor. The escaping gas spins one, and the other forces extra air into the engine.

  • What does naturally aspirated mean?

    A naturally aspirated engine breathes on its own. Each piston moving down creates a vacuum, and atmospheric pressure alone fills the cylinder behind it.

  • What is a hot hatch?

    A hot hatch is an ordinary small hatchback given a much stronger engine and a firmer, sharper chassis. Nobody certifies the label, which is why the arguments never end.

  • What is a supercar?

    A supercar is an extreme performance car, expensive and built in small numbers. There is no threshold of power, price or speed that officially makes one.

  • What is a JDM car?

    JDM stands for Japanese Domestic Market. Literally it describes where a car, part or specification was built to be sold: inside Japan, rather than exported.

  • What does GT mean on a car?

    GT is short for gran turismo, Italian for grand tourer: a car built to cross long distances quickly and comfortably rather than to lap a circuit.

  • The car

    What the numbers on the spec sheet actually measure, how the engine breathes, and which of these words mean anything at all.

The art

  • The art

    The picture itself. One of the twenty-eight already drawn, your own car repainted from a photograph, or that photograph printed as it is.

By car

  • Supercar Posters

    Supercar posters are usually photographs - which means licensing, which means the same dozen press shots on every site. Ours go the other way: original supercar art in the spirit of the…

  • Muscle Car Posters

    Muscle car posters should sound like they look: big-displacement, unsubtle, a little chrome-edged. The V8 is the heart of the genre, so we drew the heart itself - V8 Anatomy is an…

  • Rally Posters

    Rally is the discipline where cars leave the ground and posters earn their drama. Our rally-adjacent pieces chase that energy: The Hairpin catches a vintage racer mid-drift on a…

  • Endurance Racing Posters

    Endurance racing is the romantic discipline - twenty-four hours, headlamps at dusk, the long game. Endurance is our flagship tribute: a long-bonneted sixties prototype on an endless…

  • Hot Hatch Prints

    The hot hatch is the people's performance car - shopping trolley silhouette, motorsport heart - and it deserves wall art with the same wit. Our nineties-flavoured pieces carry the…

  • Classic American Car Prints

    Classic American car prints trade on a specific dream: empty highway, big sky, chrome catching the golden hour. Route Nowhere is that dream painted - a fifties cruiser on cracked desert…

  • British Classic Car Prints

    British classic car culture is roadster culture: low doors, long louvred bonnets, weather optional. 1930: The Roadster opens our Silhouette Era set with exactly that shape - swept wings…

  • Roadster Prints

    The roadster is the purest car shape there is - two seats, no roof, nothing it does not need - and it draws beautifully. It opens our Silhouette Era set as 1930: The Roadster, one…

  • Classic Car Posters

    A classic car poster should feel like the era it celebrates, not a stock photo of another car. Ours are original art drawn in the spirit of the golden age - Pit Lane, 1955 captures the…

  • Car Posters for Bedrooms

    Car posters for a bedroom have to pass a harder test than garage art: you fall asleep looking at them. Loud photography dates fast; original art lasts. The Night Drives series was…

  • Car Posters for Boys' Rooms

    Car posters for a boy's room usually mean a cheap multipack that peels off the wall in six months - fast to fade, faster to outgrow. Original art goes the other way: a print they choose…

  • Car Prints for the Office

    Car prints for an office have a diplomatic mission: signal the passion without undermining the professionalism. Photography of someone else's supercar fails that test; original art…

  • Man Cave Wall Art

    Man cave wall art carries the whole room's identity - it is the difference between a den with a sofa and a place with a point of view. The Garage series was painted for these walls: The…

  • Car Art for the Living Room

    Living room car art has to earn a place among the furniture, not shout over it. Canvas suits the room - no glass glare, a soft gallery edge - so The Workshop and Riviera Run sit as…
