The Volvo Group is a Swedish multinational manufacturing company headquartered in Gothenburg. Its principal activity is the production, distribution and sale of trucks, buses and construction equipment. Volvo also supplies marine and industrial drive systems and financial services. Although the two firms are still often conflated, Volvo Cars, also based in Gothenburg, has been a totally separate company since it was sold off in 1999. The companies still share the Volvo logo and co-operate in running the Volvo Museum.Volvo was established in 1915 as a subsidiary of SKF, the ball bearing manufacturer, however the Volvo Group and Volvo Cars consider themselves to have been officially founded on 14 April 1927, when the first car, the Volvo ÖV 4 series, affectionately known as "Jakob", rolled out of the factory in Hisingen, Gothenburg.Volvo means "I roll" in Latin, conjugated from "volvere", in relation to ball bearings. The brand name Volvo was originally registered as a trademark in May 1911 with the intention to be used for a new series of SKF ball bearings. This idea was only used for a short period and SKF decided to simply use "SKF" as the trademark for all its bearing products.In 1924, Assar Gabrielsson, an SKF sales manager, and engineer Gustav Larson, the two founders, decided to start construction of a Swedish car. Their vision was to build cars that could withstand the rigors of the country's rough roads and cold temperatures.AB Volvo began activities on 10 August 1926. After one year of preparations involving the production of ten prototypes the firm was ready to commence the car-manufacturing business within the SKF group. AB Volvo was introduced at the Stockholm stock exchange in 1935 and SKF then decided to sell its shares in the company. Volvo was delisted from NASDAQ in June 2007, but remains listed on the Stockholm exchange. Wikipedia.

Fuel economy is a key aspect to reduce operating costs and improve efficiency of freight traffic, thus increasing truck competitiveness. The main objective of the IMPERIUM project (IMplementation of Powertrain Control for Economic and Clean Real driving EmIssion and ConsUMption) is to achieve fuel consumption reduction by 20% (diesel and urea) whilst keeping the vehicle within the legal limits for pollutant emissions. The approach relies on three stages targeting the improvement of the control strategy: * Direct optimisation of the control of the main components (engine, exhaust after-treatment, transmission, waste heat recovery, e-drive) to maximize their performances. * Global powertrain energy manager to coordinate the different energy sources and optimize their use depending on the current driving situation. * Providing a more comprehensive understanding of the mission (eHorizon, mission-based learning) such that the different energy sources can be planned and optimized on a long term. The IMPERIUM consortium consist of major European actors and is able to provide a 100% European value chain for the development of future powertrain control strategies for trucks.

6 of the European carmakers (DAIMLER, VW, TME, CRF, VOLVO, Opel), under the coordination of EUCAR, have joined forces to commonly address the high cost issue of innovations in vehicle lightweighting, having identified it as the major bottleneck towards their implementation in vehicle series and mass production. The AffordabLe LIghtweight Automobiles AlliaNCE (ALLIANCE) has the ambition to develop novel advanced materials (steel, aluminium, hybrid) and production technologies, aiming at an average 25% weight reduction over 100k units/year, at costs of <3 /kg. Additionally, ALLIANCE will develop a mass-optimizer software tool and a multi-parameter design optimisation methodology and process, aiming at an accelerated pre-assessment of technologies over existing designs in a holistic framework. ALLIANCE will work on 8 different demonstrators of real vehicle models, 6 of which will be physically tested, aiming at market application by OEMs within 6 years from project end (in 2025). A transferability and scalability methodology will also be developed for results replication across other vehicle components and models in other segments. ALLIANCE aims at becoming a central hub for innovation in lightweight design in Europe. To do so, it will establish an open inclusive framework towards external centres and clusters in this field, involving them in ALLIANCE development through an open lightweight design contest and dedicated workshops.
