General information about the car (Renault Sandero 1)

Renault began developing the Sandero model in 2005. Full-scale production of the Renault Sandero at the Ayrton Senna plant in Curitiba (Brazil) began in December 2007. The European premiere of the Sandero model took place in March 2008 at the Geneva Motor Show. Serial production of the car began that same year (under the Dacia brand) in Romania, and in 2009 - in South Africa. Since 2009, the Dacia Sandero has been sold in Belarus and Ukraine. Since December 2009, the Sandero model has been produced under the Renault brand at the Moscow Avtoframos plant. Sales of the model in Russia began on March 1, 2010.

In Russia, Renault Sandero cars are equipped with petrol engines: 8-valve 1.4 l (75 hp) and 1.6 l - 8-valve (87 hp) and 16-valve (102 hp).

The hatchback body is a load-bearing, all-metal, welded structure with hinged front fenders, side doors, hood and tailgate.

The transmission is made according to the front-wheel drive scheme with front wheel drives equipped with tripod-type constant velocity joints.

The cars are equipped with a five-speed manual or four-speed automatic transmission. Manual transmissions installed on cars with engines with a working volume of 1.4 and 1.6 liters are almost identical in design, have the same gear ratios and differ only in the size of the clutch housing, which is caused by the use of clutches of different diameters on these engines.
