Extensive use of higher strength steel makes the new bodyshell lighter and stiffer than before as well as offering refinement in underbody design. This latest body design has also helped improve impact safety for pedestrians as well as occupants.
Increased track and larger diameter wheels with lower profile tyres allow for even better handling than the outgoing Swift that first went on sale in 2005. New Swift has grown slightly in length (+90mm) with a 50mm increase in wheelbase.
For the powertrain; a new 1.2-litre petrol engine incorporating Dual VVT (Variable intake and exhaust valve timing) is utilised which produces 94 PS at 6,000 rpm, slightly more than the outgoing 1.3-litre unit. Torque is also improved to 118 Nm at 4,800 rpm.
Fuel consumption on the combined cycle is now 56.5 mpg for the manual transmission model, an improvement of 7.8 mpg over the previous 1.3-litre unit. Emissions are much lower as well; the new 1.2-litre engine with manual transmission produces 116 g/km on the combined cycle; representing a 24 g/km or 17 per cent improvement over the 1.3. An optional automatic transmission will be available for the petrol engine from launch.
A 1.3-litre diesel engine will also become available and planned for UK introduction in early 2011; this engine emits 109 g/km (down from 119 g/km) and has a combined fuel consumption of 67.3 mpg, an improvement on 62.8 mpg from the outgoing Swift DDiS. This Euro 5 engine has more precise engine management than before with reduced levels of mechanical friction.
