Accent remains an expensive proposition, at $36,490 for a diesel sedan. That's a lot for a small car, although it's not actually that small. Accent sits in a slightly awkward spot, the four-door being quite a bit larger than the model it's supposed to sit underneath, the soon-to-be-replaced i30. The Accent is 125mm longer than an i30 hatchback and boasts a cavernous 465-litre boot.
Diesel is a no-brainer if you've any interest in enjoying the drive. It's also a rare thing: there are few small sedans with diesel engines on the market.
However, I fear it doesn't make much sense in money terms: dowdy though it may be, the petrol/auto combination is still quite thrifty at 6.4 litres per 100km. The diesel is better still, but by less than a litre per 100km.
The premium for diesel power is very high: $4500 over the equivalent petrol Accent sedan. Crunch those numbers and with Road User Charges (RUC) in the frame, you'll have to do over 600,000km to recoup the price.
The Accent diesel can be enjoyable to drive. But it's not that enjoyable.
The bottom line:
Grunty diesel power addresses the Accent's powertrain problems, but highlights a whole new issue: economics. Fuel economy is too close to the petrol; the price premium too large for it to make sense.
