New engine and transmission aims for improved efficiency
In a bid to expand their Ingenium family of engines, Jaguar introduces new petrol units which will likely enter production and will be available by 2017.
Technical specifications and details are scarce at the moment, however the British manufacturer says they will employ electrohydraulic valvetrains, integrated exhaust manifolds, as well as twin-scroll ceramic ball bearing turbocharging technologies for their next slew of motors. All this will supposedly yield “exceptional performance, efficiency and refinement while meeting the most stringent global emissions regulations.”
In 2015, Jaguar released an Ingenium 2.0-liter turbo-diesel motor that characterizes itself as a modular unit capable of being inserted into sedans, coupes, and SUVs with rear or all-wheel drive. The new petrol Ingenium motors will likely take after the architecture of their diesel counterparts.
“Ingenium has been developed as a modular family of powerful, efficient and refined all-aluminum petrol and diesel engines,” said Nick Rogers, Jaguar Land Rover’s engineering director.
Aside from working on a new petrol engine, Jaguar are also working on addressing losses from their transmissions as well. Dubbed the ‘Transcend’, Jaguar’s new eight-speed automatic will have an ultra-wide ratio spread of 20:1 – more than double that of their conventional eight-speed auto. The new transmission will also supposedly be 20kgs lighter than the current automatic transmission in Jaguar’s lineup, and will also supposedly fit in rear and all-wheel drive applications. Jaguar claims that this new transmission is 10% more efficient than other transmissions.
“Environmental innovation is at the heart of our strategy to dramatically reduce emissions up to 2020 and beyond,” Rogers explains. “With the Ingenium family of powertrains and advanced research projects such as Transcend, future Jaguar Land Rover vehicles will emit significantly less CO2. By 2020, new technologies will help us reduce our CO2 emissions by a further 25 percent.”
