| CRUISING: The Holden Astra CDTi features two variants that are economical to run. |
|
Let me admit my bias upfront – I’ve always been a fan of the Holden Astra.
The mid-size European five-door hatch is well made, roomy, reliable, attractive and a pleasure to drive.
The accolades continue with the marketing of two 1.9-litre diesel-engined variants.
The first is a more powerful version equipped with a twin overhead cam/four-valve engine that generates 110kW connected to a sweet-shifting six-speed box.
The second is a less powerful two-valve engine with 88kW on tap, mated to a six-speed automatic.
Yes, both engines have a noticeable chatter at idle and there is a slight lag on take-off, but owners will have a smile at the fuel pump.
Around town, I achieved about 6.5-7 litres per 100km on both vehicles. On the open road, according to the trip computer, I achieved about 5 litres per 100km on the manual and about 6 litres per 100km on the auto.
In line with their power differences, both models have different suspension tweaks – the manual has distinctly sporty settings while the auto soaks up the bumps in a more refined manner.
However, both models exhibit excellent road-holding and it’s only during “press-on” motoring that the manual’s superior manners are noticed.
The beautifully-weighted steering, combined with a healthy amount of rubber on the road to handle the extra torque from the diesel, makes driving in the twisties a cinch.
Safety is well catered for with first-class brakes, six air bags, ABS and electronic stability control.
Inside, extra room is available through split rear-seating.
Although the interior is rather basic and the sound system could be improved, both Astras are very comfortable on a long trip.
Cruise control is standard but a quick check with the driver’s manual helps familiarisation.
In summary, potential buyers have to look carefully at the extra dollars when purchasing a diesel and whether they can amortise these costs over their intended ownership.
And my verdict on the two cars tested? I enjoyed the extra performance of the manual, but for my money, I loved the ease and convenience of the six-speed auto.
