Style guides are essential for magazines, newspapers, websites and anywhere else where text is regularly published. The idea of the style guide is to record commonly mis-spelled words and names, notes on usage of words and phrases, spelling and punctuation choices and so on. Often there is more than one way of spelling a word or presenting, say, an abbreviation or trade name, so the style guide gives guidance on the style the publication prefers.

Most of the style guides available online – like the well-known Guardian Style – are for newspapers and magazines with a wide-ranging remit. For specialist titles it's useful to have a style guide which concentrates on specialist words, so what follows is an automotive style guide which I'll add to and update from time to time. If you have any additions or corrections please let me know.

A

abbreviations
as a general rule, use capitals if the letters are pronounced separately (BMW, EBD) but not if the abbreviation is pronounced as a word (Avus, Vtec)

ABS
a Bosch trade name, but its use as a generic for anti-lock braking system is now so widespread there is little point distinguishing between Bosch and non-Bosch systems

Airikkala, Pentti
(1945-2009) British Rally Champion 1979 and left-foot braking evangelist

Alfa Romeo
no hyphen, except for very early cars Aston Martin no hyphen, except in its very earliest days

Austin-Healey
hyphenated

Avus
German race track

Bilstein
dampers

Blydenstein, Bill
(-2007) Vauxhall tuning expert and former racing driver

brake, braking
when referring to vehicle retardation

Brawn, Ross
motorsport engineer and team principal

Button, Jenson
not Jensen; 2009 F1 World Champion

C

caliper
not calliper

carburettor
but note the SU company always used 'carburetter'

Carello
lamp manufacturer

Carillo
con-rod manufacturer

Citroën
not Citreon, and note the position of the umlaut

concours
a competition where old cars are judged for condition and originality

concourse
part of a railway station

Cortina Lotus
the Lotus-engined Mk2 Cortina - see Lotus Cortina

D

DaimlerChrysler

damper
do not use 'shock absorber', because the term is misleading - they don't absorb shock, they damp spring movement

Dell'Orto
Italian carburettors

Donington Park
note single n; do not refer to the circuit as Castle Donington, which is the village nearby

F

fascia
not facia

Fiat X1/9

Fibreglass
is a trade name and should not be used as a generic - use GFRP or glass fibre

front-wheel drive

G

GFRP
glass fibre reinforced plastic, commonly (but imprecisely) called glass fibre

glass fibre
two words

Goodrich
tyre manufacturer; BF Goodrich is part of the Michelin group

Goodridge
reinforced hose manufacturer

Grand Prix

GTi
for Golfs before September 1993

GTI
for Golfs September 1993 onwards

H

hybrid engine
is nonsense. A hybrid is something made up of two or more things, and the point about a hybrid vehicle is that it has two or more 'engines' - usually a petrol or diesel engine and an electric motor.

I

Isky
valve spring manufacturer

Issigonis, Alec
(1906-1988) not Alex; BMC chief engineer, responsible for the Mini

J

Jensen

L

early models carried a hyphen, but for consistency refer to the company and all its products without one

Lotus Cortina
Mk1 Lotus-engined Cortina; see Cortina Lotus

M

MacPherson strut
suspension system named after Earle MacPherson. Consists of a strut and a wishbone, so don't say 'MacPherson strut and wishbone'.

Mercedes-Benz
hyphenated; note that the parent company is Daimler-Benz, so use this name with care

Michelotti, Giovanni
(1921-80) Italian car designer

Mikuni
carburettors

Mini
not MINI, even for the BMW Minis

Minilite
note not all Minilite-style wheels are made by this company

model names
The general rule is to use what the manufacturer used, but this is complicated if the manufacturer was itself inconsistent – Jaguar, for example, has used E-type, E Type and 'E' type across its advertising, brochures and car badges. So there's a norm among enthusiasts of the marque/model, use that. If not, choose the simplest form that clearly identifies the car.

O

Odor, Jan
founder of Janspeed

Odor, Kieth
(1962-95) son of Jan, racing driver killed in a touring car race at Avus
