Lets have more on NANO’s MECHANICAL style

Rear mounted engine

The use of a rear mounted engine to help maximize interior space makes the Nano similar to the original Fiat 500, another technically innovative “people’s car”. A concept vehicle similar in styling to the Nano, also with rear engined layout was proposed by the UK Rover Group in the 1990s to succeed the original Mini but was not put into production.The eventual new Mini was much larger and technically conservative. The independent, and now-defunct, MG Rover Group later based their Rover CityRover on the Tata Indica.
Tata is also reported to be contemplating offering a compressed air engine as an option

Technical specifications

According to Tata Group’s Chairman Ratan Tata, the Nano is a 33 PS (33 hp/24 kW) car with a 623 cc rear engine and rear wheel drive, and has a fuel economy of 4.55 L/100 km (21.97 km/L, 51.7 mpg (US), 62 mpg (UK)) under city road conditions, and 3.85 L/100 km on highways (25.97 km/L, 61.1 mpg (US), 73.3 mpg (UK)). It is the first time a two-cylinder non-opposed petrol engine will be used in a car with a single balancer shaft.Tata Motors has reportedly filed 34 patents related to the innovations in the design of Nano, with powertrain accounting for over half of them. The head of Tata Motors’ Engineering Research Centre, Girish Wagh has been credited with being one of the brains behind Nano’s design.

According to Tata, the Nano complies with Bharat Stage-III and Euro-IV emission standards. Ratan Tata also said, ‘The car has passed the full-frontal crash and the side impact crash’.

– Designed with a family in mind, the Nano has a roomy passenger compartment with generous leg space and head room.

– Can comfortably seat four persons. Four doors with high seating position make ingress and egress easy.

– With a length of 3.1 metres, width of 1.5 metres and height of 1.6 metres, with adequate ground clearance, it can effortlessly manoeuvre on busy roads in cities as well as in rural areas.

– Its mono-volume design, with wheels at the corners and the powertrain at the rear, enables it to uniquely combine both space and manoeuvrability, which will set a new benchmark among small cars.

– The Nano has a rear-wheel drive, all-aluminium, two-cylinder, 623 cc, 33 PS, multi point fuel injection petrol engine. This is the first time that a two-cylinder gasoline engine is being used in a car with single balancer shaft.

– The lean design strategy has helped minimise weight, which helps maximise performance per unit of energy consumed and delivers high fuel efficiency.

– Performance is controlled by a specially designed electronic engine management system.

– The Nano’s safety performance exceeds current regulatory requirements. With an all sheet-metal body, it has a strong passenger compartment, with safety features such as crumple zones, intrusion-resistant doors, seat belts, strong seats and anchorages, and the rear tailgate glass bonded to the body.

– Tubeless tyres further enhance safety.

– The Nano’s tailpipe emission performance exceeds regulatory requirements. In terms of overall pollutants, it has a lower pollution level than two-wheelers being manufactured in India today.

– The high fuel efficiency also ensures that the car has low carbon dioxide emissions, thereby providing the twin benefits of an affordable transportation solution with a low carbon footprint.

  3. Very impressive site. You post on Hoists brought me here.
    With rear mounted engine, one wonders how effective braking and controlled cornering would be. Torque reaction with lighter front and heavier rear would give a front lifting jerk, like one gets in the auto(the piaggio make with rear engines) while moving from standstill. Speaking of Autos, is not Nano platform same as that of Tata Ape? How much is in common, any idea?
