Audi A3 1.9 TDI SE

Joining the range alongside the more expensive 2.0-litre TDI, the 1.9 is the entry-level diesel model. With a power output of only 104bhp, this is not a quick car, with a 0-62mph time of 11.4 seconds - that's 1.9 seconds slower than the 2.0-litre model - and it can feel underpowered and lacking in refinement. On the plus side, Audi claims a combined economy figure of 53.3mpg, and on a lengthy motorway cruise we averaged nearly 60mpg.

What's more, Euro IV compliant emissions mean that there are tax breaks for company car users. However, the bad news is the 1.9 TDI doesn't offer the value for money buyers might expect. At ΂£18,730, this SE version is ΂£1,200 more than the cheapest 2.0 TDI, and only ΂£800 less than the equivalent spec, higher-capacity diesel.
