The Solaris Urbino 12 LE lite hybrid is designed to use 30 litres of fuel per 100 km
Polish electric vehicle manufacturer Solaris will present three new EVs at the 14th International Fair of Public Transport TRANSEXPO in Kielce, which will be held on 23-25 October of 2018.
One of them will be a completely new product of the company – the Solaris Urbino 12 LE lite hybrid. The two other products are well-known on the market: the Solaris Urbino 12 electric and the Solaris Urbino 12 hybrid. These buses will debut in new versions, which received an automotive “facelift”.
Solaris Urbino 12 LE lite hybrid features low fuel consumption reducing the costs of exploitation in comparison to similar products available on the market. The main objective of the engineers of the Solaris Research and Development Office, who developed the Urbino lite hybrid, was to create a bus that would consume less than 30 litres of fuel per 100 km in the SORT 2 test.
The engineering work was focused on multiple areas in order to accomplish the above, but one of the main factors was reduction of the vehicle’s weight. The curb weight of the Solaris Urbino 12 LE lite hybrid is under 9 tonnes and its weight with passengers is 15 tonnes.
The heart of the drive system in the new Urbino model is the Cummins ISBE6 engine with a volume of only 4.5 litres. The unit, which fulfils the restrictive EURO 6 exhaust emission standard, has 210 HP and torque of 850 Nm.
The drive system of the Urbino LE lite hybrid is also equipped with an electrical machine with nominal power of 11.5 kW, which is tasked with recuperating energy during the braking process and supporting the combustion engine when the vehicle starts moving, which consequentially leads to it consuming less fuel.
The Solaris Urbino 12 LE lite hybrid will be accompanied at the Transexpo fair by two other buses: the Solaris Urbino 12 electric and the Solaris Urbino 12 hybrid with serial hybrid system, which are already well-known on the market but will debut with a new design, which will become the standard for all Urbino and Trollino city vehicles as of January 2019.
“The endless changes on the automotive market, specifically the ones in the field of buses, force continuous development of new products in order to meet the growing expectations of our clients: drivers, passengers, and buyers of the vehicles we design and make.
“Due to the above, we are currently introducing further improvements in Solaris city buses, four years after releasing the current generation to the market. The facelift is evolutionary and optimises the current solutions. We are certain that we have discovered the right combination of style and function to increase the attractiveness and pleasure from using our vehicles even more,” explains vice-president of the Solaris management board in charge of research and development, and quality assurance Dariusz Michalak.
