Daihatsu Sirion 2007
The new Daihatsu Sirion is a totally differently proportioned car to its predecessor and more closely matches the Nissan Micra for length, width and height but with passenger space rivalling the considerably longer Honda Jazz.
The wheelbase of 2,430 mm is 85 mm longer than the old model and the 1,665 mm width is 70 mm more and even 5 mm greater than the Toyota Yaris, Nissan Micra and Fiat Punto. Height grows by 100 mm to 1,550 mm - 10 mm greater than the Micra.
The car looks especially wide and squat - helped by the strong swage lines over the wheelarches flowing into a protruding rear bumper. The overall effect is of a confident, well-balanced design exuding quality and solidity.
An especially impressive drag coefficient of 0.31 Cd confirms the new Daihatsu Sirion's efficiency and aids fuel economy and top speed while reducing wind noise.
As Yoshihiro Fujibayashi, Studio Leader, Styling Division, Daihatsu Motor Co, Ltd said: "We tried to give the car sculpture-like dimensions and a sense of quality. Look at the handsome, chiselled face around the headlamps, the animated and dynamic side view and the rear combination lamps integrated into the bodylines.
Impressive Interior Space
The new Daihatsu Sirion has occupant legroom and headroom from the next-size-up. Its interior width of 1,400 mm is 70 mm greater than before and 10 mm more than the Toyota Yaris.
The interior length of 1,830 mm is 20 mm more than the Yaris while the interior height is also greater than the Toyota.
World-Class Engines
The new Daihatsu Sirion boasts two of the world's most efficient 1.0 and 1.3 litre petrol engines, combining strong driveability with ultra-low fuel consumption and exhaust emissions.
All-New One Litre
The three cylinder, twin-overhead camshaft 1.0 litre is all-new and is bigger than before with a 998 cc capacity (was 989 cc), and a slightly smaller 71 mm bore and longer 84 mm stroke (was 72 x 81 mm).
This gives greater low-speed torque or pulling power, while the Dynamic Variable Valve Timing (DVVT) allows a wider spread of high-end power and low-speed flexibility.
The new 12-valve 1.0 litre's maximum power of 69.3 PS at 6,000 rpm is exceptionally high for its size, while the 69.3 lb.ft torque is also impressive - especially at an accessible 3,600 rpm. The compression ratio is 10.5:1.
Unrivalled Performance, Economy And Emissions
No rival can match the new Daihatsu Sirion 1.0 litre's performance, fuel economy and low emissions.
The top speed is a remarkable 99.4 mph with a 0-60 mph time of 13.5 seconds. Fuel consumption is an outstanding 46.3/64.2 and 56.5 mpg on the Urban/Extra Urban and Combined Cycles.
An exceptionally low CO2 emissions of 118 g/km means the car qualifies for a Road Fund Licence charge of only £75 for 12 months plus £38 first registration fee (AA band up to 120 g/km). This places it in a category largely dominated by hybrids - and the smaller Daihatsu Charade, of course.
Throughly Revised 1.3 Litre
The new Sirion's four-cylinder 1.3 litre engine has been thoroughly revised to provide stronger low-speed torque and a more useable power delivery in day-to-day driving.
With a compression ratio of 10.3:1, this compact, light, all-alloy engine has bore and stroke dimensions of 72 x 79.7 mm and - like the 1.0 litre - employs durable chains for its camshaft drive.
Top speed for the manual is 106 mph with the four-speed automatic only slightly slower at 102 mph. The former has a 10.9 second 0-60 mph time while the automatic takes 12.6 seconds.
Fuel economy is outstanding for both at 37.7/58.9 and 48.7 mpg on the Urban/Extra Urban and Combined Cycles for the manual and 32.8/54.3 and 44.1 mpg for the automatic. CO2 emissions are among the lowest in the Daihatsu Sirion's class at 137 and 151 g/km respectively.
World's First Self-Regenerating Catalyst
The new Daihatsu Sirion 1.3 litre features the world's first self-regenerating catalyst. This effectively extends the life of the catalytic converter, reducing maintenance costs.
It also is kinder to the environment as it keeps the catalyst 'healthier' over a higher mileage meaning the already low 137 g/km CO2 emissions do not increase as the engine becomes older.
This revolutionary technology works by providing a self-regenerating capability in the particles of the precious metal which normally degrades.
Using nanotechnology, the intelligent catalyst incorporates metallic ions of palladium, the most heat-sensitive of the metals used in a catalytic converter.
European-Tuned Chassis
The new Sirion's suspension has been thoroughly proven on a variety of European roads and tuned for suppleness and stability.
The front employs MacPherson struts and coil springs while the rear uses the equally popular and well-proven semi-independent torsion bar system with separate coil springs. With almost vertically-mounted shock-absorbers, this reduces the transmission of road noise and makes the damping more effective.
Straight-line stability is especially strong and the steering self-centres well, avoiding the vagueness and lane-wander of some electric systems.
Class-Beating Turning Circle
Despite having one of the widest tracks and bodies in its sector, the new Daihatsu Sirion boasts a class-beating turning circle.
Coupled with excellent visibility and a seating position higher than the norm, parking is made that much easier - aided by rear parking sensors on SE models.
In fact, with a kerb-to-kerb turning circle of 9.4 metres, the Daihatsu Sirion is 0.4 metres tighter than the Ford Fiesta or Toyota Yaris, 0.6 metres better than the Vauxhall Corsa and a massive 0.9 metres more agile than the Renault Clio.
Top Level Safety Package
Every aspect of safety has been studied for the new Sirion with the aim of achieving 4-stars in the Euro NCAP tests.
The body was subjected to the world's most rigorous crash tests including full-on frontal and side-impact collision tests at 55 km/h, a rear impact at 50 km/h and a frontal offset collision test at 64 km/h.
All main frame members are straight, joint rigidity is optimised and suspension mounts reinforced. High-tensile steel is used where needed and bonnet and bumpers are designed to lessen injury to pedestrians.
The door pillars and roof sides have special ribs which reduce possible head injury while both the brake pedal and steering wheel have been designed to avoid intruding during a frontal impact.
Unbeatable Equipment Levels
There is no such thing as a 'basic' entry-level Daihatsu Sirion despite prices starting at £6,995 OTR. Every model has unbeatable equipment levels.
The Daihatsu Sirion 1.3 S adds, for example, rear speakers, electric door mirrors, driver's seat height adjustment, chrome interior door handles and a front passenger seat back pocket.
The Daihatsu Sirion also boasts highly competitive insurance groups of 4D for the 1.0 S, 5D for the 1.0 SE and 6D for the 1.3 - both helping reduce running costs.
