Spotlight on Ulrik Grape Ulrik Grape, president Ener1 Europe, gives Ian Adcock an insight into the future of EVs Technological Tour De Force This year's SAE World Congress was a showcase for advanced technologies. We highlight those that impressed most Wankel's new lease of life Once dismissed for its oil consumption and high wear rates, Wankel rotary engines could be reborn in a range extender, as Ian Adcock discovers

Joining metal/composite structures The interference-fit bolted joining of hybrid metal/composite can greatly improve the fatigue life of such joints, according to Chinese researchers.

Perking up fatigue analysis with simulation Using CAE simulation tools for fatigue and durability offers advantages to off-highway equipment engineers as they have grown in capability.

Oil debris monitoring in aero engines In a gas turbine engine, small particles or "chips" are generated at the point of wear, serving as an advanced warning that catastrophic failure will occur if the wear is not addressed. Health monitoring systems, such as oil debris monitoring, are used to find these small particles so that the wear can be resolved before it's too late. Indigenous powertrain development Customer needs and expectations on drivability, fuel economy, and safety has pushed Indian and multinational OEMs to think about the development of powertrains and gearboxes for local needs with global standards. The next wave of crash simulation As computing speed has improved and software itself has made significant speed and performance gains with each release, modeling tools are now quick enough to build high-quality, large, high-detail vehicle models in a very efficient manner.

QT steels make an impact The use of quenchd and tempered steels for dumper bodies reduces weight and fuel consumption while increasing payload capacity and wear life.

Thought leadership at WCX17 Lucid Motors' David Moseley: EV or ICE, "It is all physics" New eye on the road One of the industry's hottest tech suppliers is blazing the autonomy trail by crowd-sourcing safe routes and using AI to learn to negotiate the road. Mobileye's co-founder and CTO explains. Hard, slick and ready to roll A tough, self-renewing catalyst coating developed at Argonne National Laboratory provides unprecedented friction and wear protection for vehicle powertrains, the inventors claim.
