The Impuls family of trains are low-floor, electric multiple units equipped with a full interior monitoring system, air-conditioning, passenger information system and can have ticket dispensers if requested. Their interior is suitable for the needs of passengers with reduced mobility. It features sloping floors, folded steps, broad aisles and a designated space for wheelchairs and bicycles. In the vehicle, motor bogies are used as well as Jacobs bogies. The bogies have a modern gear system and two-stage spring suspension systems that effectively muffles vibrations, thus enhancing comfort while travelling. The trains can be built in various configurations. The two-car variant is known as "37WE", three-car "36WE", four-car "31WE", five-car "45WE" and six-car "35WE". The trains can have interiors built suitable for commuter and suburban trains but also for long distance routes. The first design was launched in 2012. One of the trains produced for Koleje Dolnośląskie, broke the Polish speed record of in 2013 on the test track, on 7 September 2015, a Newag Impuls 45WE unit for Koleje Mazowieckie once again topped this record with what is now the current one, which makes it the fastest passenger train produced in Poland. Newag launched a second generation of the design, named Impuls II, in 2017 with an order of 14 trainsets from Łódzka Kolej Aglomeracyjna.
