Maximum side slope is 30% and vertical step about 0.6 metres. The angles of approach and departure are 35°. The nominal fording depth is 0.8 m, but 1.2-metre depth is achievable with preparation. Uphill start is possible on this gradient by help of interlocks. On dry and stiff surface the vehicle is capable to climb 60% steep uphill and downhill forward and by reversing. The E15TP is fitted with 26-metre MLC70 Leguan bridge and launching system produced by the German company KMW. A firefighting and rescue vehicle with a decouplable 10-ton extinguishing container was presented in 2012. An application with NASAMS air defence system was introduced in Norway in June 2010. The modular design enables a wide variety of superstructures and applications, such as hook loader and radar or launcher carrier. The frame is designed to withstand high torsional stress. The chassis is mine-protected the pneumatic, electric and fuel systems are placed in protected areas, for example behind the cabin. The cabin is produced from Ruukki Ramor steel and fitted with pressurised NBC protection system. Armoured steel doors provide STANAG 4569 level 1 ballistic protection levels 2 and 3 are reached with optional composite doors. Cabin and engine mine protection is installed on the chassis under the cabin and on the floor in accordance with STANAG 4569 levels 3a and 3b against anti-tank mine blasts up to 6 kg.

Mine, ballistic and NBC protections are optional the mine and ballistic protection can be also mounted afterwards.

The cabin contains seating for driver and one passenger. In this variant all the axles are with lockable differentials and there are four interaxle locks the first, second and last axle are steering. The E15TP 10×10 is equipped with a 7-speed automatic Allison. All axles are driven and produced by Sisu Axles. The Steyr VG 2000/300 2-step reduction gear contains longitudinal, lockable differential between the front and rear axles. The gearbox used in E13TP 8×8 models is an automatic 6-speed Allison HD4500SP with a torque converter. Its displacement is 15.2 litres, bore 137 mm and stroke 171 mm. Also this model is a six-in-line turbocharged diesel engine. Į15TP is equipped with a stronger Caterpillar engine, C15. The engine includes heaters for lubricating oil, cooling water and cabin. Its output is 332 kW and the maximum torque is 2270 Nm /1200 1/min. It is equipped with a cross-flow breathing cylinder head. The six-in-line, 12.5-litre diesel has bore of 130 mm and stroke of 157 mm.

Technical data Engine Į13TP is powered by Caterpillar C13 turbo-diesel engine. Ī 10×10-driven variant E15TP with a more powerful engine was introduced in Eurosatory 2006 exhibition.

The deal was followed by further E13TP orders. Lithuanian Armed Forces ordered 24 vehicles which were delivered between 2007–2009 the first units entered in service in 2008. Eventually, in the same December it was announced Sisu became selected. Eight manufacturers from United States and Europe took part in the tender process the three shortlisted producers were Iveco, MAN and Sisu. Lithuania raised a tender for Level 2 protected armoured lorries at the end of 2005. In March 2004 Lithuania joined an alliance to support NATO in remote peacekeeping and humanitarian missions, which it dedicated to a specific unit in the Armed Forces. In order to lower the operating costs and ensure availability of spares, large amount of the parts are standard components. The Finnish Defence Forces participated at the development work.

It is heavily based on the preceding E11T model the main differences are bigger engine displacement, armoured cabin and upgraded gearbox. Sisu E13TP is developed for military and peacekeeping missions in particular.
