Jaguar Land Rover expanding Ingenium powertrain family; new gasoline engine, TRANSCEND transmission
12 September 2016
This week, Jaguar Land Rover will expand its Ingenium powertrain family (earlier post), unveiling new technologies for both current and future vehicles. The new additions will support the company’s long-term commitment to reduce vehicle emissions and improve fuel economy across its range through the introduction of more efficient engines along with alternative powertrains, lighter vehicles and improved vehicle energy conservation.
At the heart of its low-emissions strategy, the new four-cylinder Ingenium gasoline engine is now in production at Jaguar Land Rover’s £1-billion (US$1.33-billion) Engine Manufacturing Centre. Designed, engineered and manufactured in the UK, these engines will deliver up to 25% more power than the engines they replace and offer fuel consumption reductions of up to 15%.
The Ingenium petrol engine features technologies such as an electrohydraulic valvetrain, integrated exhaust manifold and twin scroll turbocharger with ceramic ball bearing technology.
Using a common architecture based on a 500cc per cylinder displacement delivers both maximum flexibility and scaleability. This enables a range of derivatives to be developed to suit applications as diverse as sports sedans and luxury SUVs.
Following the launch of the 2.0-liter four-cylinder diesels in 2015, these advanced gasoline engines become the latest Ingenium engines to enter production and will be available from 2017.
Looking to the future, Jaguar Land Rover has developed an advanced automatic transmission that will both improve the efficiency of future vehicles and expand their all-wheel drive capability. The £30-million (US$40-million) advanced research project TRANSCEND uses an innovative ultra-wide ratio spread (20:1) that integrates low-range gear box, dual-clutch and hybrid technologies to deliver new levels of off-road performance and fuel economy improvements of nearly 10%.
TRANSCEND combines innovative mechanical design and advanced manufacturing techniques to deliver a compact, lightweight eight-speed transmission weighing around 20kg less than existing eight-speed automatics. TRANSCEND could be used in longitudinal rear-wheel drive and all-wheel drive vehicles.
By 2020, new technologies will help us reduce our CO₂ emissions by a further 25%.—Nick Rogers, Group Engineering Director
With part funding from the UK government, the TRANSCEND program aims to rebuild the UK’s transmission production through investment in processes to develop lighter components as well as more energy-efficient manufacturing production and promote the export of British hybrid vehicle technologies.
Since 2008, Jaguar Land Rover has doubled the number of powertrain engineers and invested in the research of a range of future powertrain solutions. This team is developing the technology that will help deliver a further 25% improvement in CO2 emissions in the next five years.
Jaguar Land Rover is also committed to introducing electrification and has confirmed its electric future with an entry for Jaguar in the innovative FIA Formula E Championship. This investment will push the boundaries of electrification technology and provides a real-world, fast-track test bed for future Jaguar Land Rover electrification technology, transferring it from track to road.
