Mazda 3 SP20 vs Honda Insight VTi

The Mazda3 Maxx Sport ($26,490 as an auto) is a more lively drive but the SP20 is better value. And it will save $410 a year in fuel ($1189 for the SP20 and $1599 for the Maxx over 15,000km). It has a six-speed auto against the Maxx Sport's five. Satnav is included but the screen's tiny.

The hybrid Insight answers questions only a few of us ask. At about 645 litres of fuel used a year (15,000km), it's frugal - the Mazda3 SP20 uses 915L. The cheaper VTi is a nice drive, is roomy and well-equipped. The battery has an eight-year warranty. Running costs are low but resale is weak.

Skyactiv uses singular components for different models to cut production costs, employs new drivetrain technology to slash fuel use, yet aims to make driving fun. The SP20's 113kW/194Nm 2.0-litre petrol engine claims a ridiculously frugal 6.1L/100km.

A new nose, low rolling resistance tyres and drivetrain tweaks bring economy down to 4.3L/100km. Combined petrol/electric output remains at 72kW/167Nm. Eco-Assist maximises economy but stifles performance. There is a stop-start system, regenerative braking and CVT.

Its wide-mouth grin apart, the car has broad appeal. It is neat, pretty and comes in a raft of bright colours (metallic paint is a no-cost option). The cabin is functional but the all-black decor makes it feel small and gloomy. The hatch has great flexibility and space.

The slippery hatch translates into a spacious family car with a flexible cabin and sensible design. New headlights and grille boost appeal. The split dash is a tad edgy but works. There are basic Bluetooth (no streaming) and plug-in connectivity. Rear vision is restricted.

Mazda also gets a five-star crash rating, has six airbags and all the modern electronic aids. But it doesn't have rear park sensors, then there's the space-saver spare. It has auto headlights and wipers.

Six airbags and electronic stability and traction control are standard and it earns a five-star crash rating. It also gets rear park sensors (unlike the Mazda) and has a spacesaver spare wheel (as does the Mazda).

The SP20's claims for the 0-100km/h sprint vary: 8.0 seconds or 10.7. It feels like the latter because the sluggish engine management system puts fuel savings before performance. It drives well and handling is secure. But the firmish ride quality could improve.

It feels brisk (despite a 0-100km/h time of 12.5sec), with the electric motor providing a hefty kick-off. Once mobile, the petrol engine does all the work. Handling is average, tyre noise too obvious. Steering feel, vague at low speeds, firms up on the highway.
