It's the first day in a new week. You've probably just rocked up at your desk, powered on your computer and taken a long, deep sigh.

Sounds like you have a case of the Mondays.

Fear not! If you've got an iPhone sitting temptingly on your desk, set it to work downloading these car-related apps for a few minutes entertainment on your next coffee break.

Car City iPhone app

Car City

Working for "the man"? This game might appeal then. It puts you in charge of a car company and your aim is to create, test and market a range of cars. Early moves are assisted by your secretary until you get used to all the features of your factory.

There's not a lot of choice early on, but you soon earn money and experience points to let you upgrade your car and factory, eventually moving on from your Beetle-esque first model to bigger and better things. The test drive option is a little bit of fun but not really comparable to other iPhone racing games. Overall though, it's a bit of escapism from the drudgery of a desk job.

We love this one. Sometimes the simple things can entertain the most - and this app has a really simple, clean interface with the chance to listen to dozens of hot cars starting up, idling and revving. Some of the sounds have been recorded better than others, but this sort of app is a must for gearheads.

Since we're a bit cheap we only downloaded the free version of this app, but a full version with far more car sounds is available for only $1 in the App Store.

Beetle Generator iPhone app

We're massive fans of an online car customizing tool called Bug Selecta, so naturally Beetle Generator suits us down to the ground. It lets you customize an early or late Volkswagen Bug with paint colors, different wheels, ride heights and more and save the resulting creation in your pictures folder.

There's not as much choice as you'll find in an online customizing tool but it brings out our creative side perfectly. At only one buck you can't go too far wrong.

Car Wallpapers iPhone app

Car Wallpapers iPhone app

10,000+ Car Wallpapers

Still got the standard bubbly background on your iPhone? That's soooo last month. What you need is a free app that lets you select from thousands of car and bike backgrounds. This is what 10,000+ Car Wallpapers gives you.

As we type, the current version, 1.3, offers retina-display compatibility so all the wallpapers should look great on your iPhone 4 and the app is updated every day with more images. Even if you don't set any of them as wallpapers, it's a great database of car images.

2010 VW GTI App Store Launch

2010 VW GTI App Store Launch

Real Racing GTI

We couldn't end this list without a racing game. Real Racing GTI is a free demo version of Real Racing 1, focusing on the 2010 Volkswagen GTI. There are six available to race, time trial, quick race and GTI Cup racing options and fantastic retina display graphics.

It's fun to race too. The car accelerates by itself but braking and steering are all yours. Braking uses a ghosted pedal near the bottom of the screen and steering is handled by tilting your iPhone left and right. It's good fun and perfect for a few minutes entertainment.
