2008 Nissan Tiida Three Engine Range EPS 126 hp
Central to TIIDA’s design philosophy was the provision of high levels of comfort and refinement, but not to the detriment of handling, vehicle stability or performance. Careful suspension tuning has created a chassis that provides fluid handling with exceptional levels of comfort, while class leading engines provide the punch.
‘It should be fairly obvious that most buyers of this sort of car regard comfort as one of the most important attributes they are looking for. TIIDA provides just that, but adds good handling and a competitive range of engines to create a great all-rounder.’

TIIDA is the latest model to use the Nissan/Renault ‘Alliance B’ platform. Originally developed for the Nissan Micra, the versatile platform now provides the hardware for the Renault Clio, Nissan Micra C+C and the Nissan Note.
Like Note, TIIDA uses a stretched version of the platform with a wheelbase of 2600mm, ideal for achieving the car’s two main goals: a roomy interior with class leading comfort.
The chassis features a tried, trusted and acclaimed combination of front-wheel drive coupled with MacPherson strut front suspension and a torsion beam rear axle. Three engine options are available, two petrol and one diesel, providing a range of power outputs from 78kW (105hp) to 93kW (126hp).
TIIDA’s front suspension features a strut-type system with combined coil-over-strut springing and a forward lower link all mounted on a sub-frame. A front anti-roll bar is attached directly to the strut assembly for more effective control of body roll.
At the rear, the torsion beam and trailing arm suspension system features separate coil springs and damper units to ensure minimal intrusion into the trunk area, while a substantial anti-roll bar keeps body roll to a minimum.
Central to the design philosophy behind the development of TIIDA is that it should provide class-leading levels of comfort and refinement. Further enhanced by engineers from Nissan Technical Centre Europe (NTCE), TIIDA’s ride quality and general refinement matches or beats that of many larger and more expensive cars.
The front sub frame, for example, has compliant rubber mounts to isolate road noise and vibrations from the platform while the use of rebound springs (as pioneered by luxury cars such as the Infiniti FX45) at the rear and ripple control shock absorbers further enhance TIIDA’s ability to soak up small road imperfections as well as providing a high level of straight line stability.
Fine handling chassis
Not that handling has been forgotten. NTCE engineers have fine-tuned the chassis for European demands by retuning spring and damper rates and revising suspension bushes. These changes, added to a rigid body shell and an inherently fine handling chassis, ensure TIIDA can tackle a winding road with as much composure as it handles city streets and motorways.
Depending on the version 15inch wheels are either steel (with full width wheel covers) or seven spoke alloys shod with 195/65 tyres.
Electric power steering
Despite the long wheelbase, TIIDA is highly manoeuvrable with a turning circle of just 10.4m. It features a state-of-the-art electric power steering system (EPS) which checks speed inputs every 40 milliseconds and is speed sensitive to 0.01 km/h. Tuned specifically for European tastes, it provides a strong self-centring action at lower engine speeds for easier town driving and greater feel at higher speeds.
Disc brakes front and rear with ABS are standard on every TIIDA, and are backed by Brake Assist and Electronic Brake Force Distribution (EBD). The advanced Electronic Stability Programme (ESP) is optionally available on every model in the range.
Three engine range
With three Euro IV complaint engines available, there’s a power unit to suit most requirements. The two petrol options, displacing 1.6 and 1.8-litres respectively, are newly developed Nissan units, while the common rail 1.5-litre diesel has been designed by Alliance partner Renault.
Both petrol engines are light-weight in-line four cylinder units designed to provide not only strong performance and good fuel economy, but also low emissions and high levels of refinement. Much of the development work has centred on reducing levels of internal friction as well as boosting low-end torque.
The entry-level version is a 1.6-litre as seen in the Micra 160SR, C+C and Note. Developing 81 kW (110hp) and 153 Nm of torque, the all-aluminium design is notably lighter than similar capacity units from rival manufacturers and is some 25kg lighter than Nissan’s previous QG family of engines.
Available with a five-speed manual transmission or a four-speed automatic, the TIIDA 1.6 has a top speed potential of 186 km/h. It returns 6.9 l/100km on the combined cycle while oil change services are needed only every 30,000 kms (approximately 18,500 miles).
Brand new 1.8-litre petrol
The range-topping petrol-powered TIIDA is driven by a brand new 1.8-litre (1797cc) version of the engine. Sharing similar design features and layout as the 1.6-litre engine, the new unit develops 93kW (126hp) and 173 Nm of torque at 4,800rpm.
Available only with a six-speed manual transmission, the TIIDA 1.8 has a top speed of 195 km/h. It returns 7.8l/100km on the combined cycle while oil change services are needed only every 30,000 kms (approximately 18,500 miles).
Known internally as the HR/MR family, both twin cam engines have four valves per cylinder, variable valve timing, multi-point port injection and vane-type continuous intake cam phasing. Notably compact, the engines have a front intake and rear exhaust layout, meaning they take up less room under the bonnet providing more for the passenger compartment.
Development on both engines focused on maximising energy efficiency with the application of a variety of technologies to eliminate energy loss and maximize performance. Crankshaft and camshaft journals, for example, are polished to a mirror-like finish to reduce friction while motor racing techniques are used to ensure the cylinder bores are as circular as possible, again to help reduce friction.
To enhance low and mid-range torque – arguably the most important requirement to satisfy everyday driving needs – the intake and exhaust system were optimised to provide the smoothest possible flow of air.
To attain complete combustion of the air/fuel mixture, thereby reducing hydrocarbon emissions and increasing efficiency, the HR/MR engines feature 12 hole fuel injector nozzles in place of the four hole versions used previously. This refinement allows an even finer particle spray – reduced by as much as 40 per cent – to promote better combustion efficiency.
Class leading diesel
With diesel still considered an ‘emerging’ trend in the markets where Tiida will be sold, it is well placed to take advantage of that growth with one of the best diesel engines currently available. The advanced turbocharged and intercooled 1.5-litre dCi unit has been developed by Renault and develops 78 kW (105hp) and a remarkable 240Nm of torque at 2,000rpm.
Acclaimed for its blend of performance, economy and low emissions mixed with refinement and smoothness, the newest version of Renault’s 1461cc eight-valve unit features the latest generation Siemens common rail technology. With a top speed potential of 186 km/h, it also returns 5.2l/100km on the combined cycle. The diesel TIIDA has a six-speed transmission as standard.
Superior Interior Quietness
TIIDA’s quiet interior is also aided by acoustic techniques applied to the development of the engines. The intake manifolds of the engines have been fine tuned to provide acoustically equal lengths, while the camshaft drive chain has been redesigned to lessen the impact noise as the pins mesh with the sprockets. This so-called ‘silent chain’ engages the sprockets at additional points thereby distributing the impact and reducing noise.
Refinement as standard
A unique pendulum engine mounting system has been adopted on TIIDA, which helps to absorb the transmission of vibration to the body shells. Enhanced noise isolation and damping materials have also been added while improved exhaust mountings and exhaust silencers help further to reduce noise penetrating the cabin.
