Mopar debuted the Hellephant 1,000-hp at the 2018 SEMA Show in Las Vegas. Drooling crowds of performance junkies stared at it like seeing barbecue after Lent. Mopar says that almost 1,000 of those junkies have been willing to buy the engine named Hellephant, which is now available for pre-order.

Aston Martin has released information about the combustion component of its insane Valkyrie hypercar's powertrain – and it's a doozy. Co-developed with Cosworth, this 6.5-liter V12 monster will make 1,000 hp, without the aid of forced induction – and in addition to electric motors.

​The engines of an airplane are complicated machines that require careful maintenance. The future of this task, as Rolls-Royce sees it, could involve deploying different kinds of of robots that patrol these aircraft parts and quickly nip any problems in the bud. ​​

It's no secret that Norton has a brand new 650cc inline twin motor in the pipeline. Scheduled to break cover in November, the Atlas 650 has been revealed for the first time in two digital renders that Norton has just released.

​A team of engineers has built and test-fired a new style of "autophage" rocket engine that eats its own structure from the bottom up during flight. They believe it could lead to cheaper, more efficient and less wasteful small satellite launches.

The working life of ion thrusters is limited by the amount of propellant they can carry. Now, scientists at ESA and Italian space company SITAEL have test-fired a new type of “air-breathing” electric thruster that could keep satellites aloft for longer, by making them literally run on thin air.

Rolls-Royce​ launched IntelligentEngine, a new initiative aimed at developing intelligent aircraft engines that are safer or more efficient. The engines would learn from their own previous experience and the experience of other engines, and may one day even be able to repair themselves.

Royal Enfield is returning to its roots with the unveiling a new 650cc parallel twin engine that's being fitted to two new models launched at the 2017 EICMA Motorcycle Show.

Mercedes is introducing a high-output four-cylinder engine to the E350 Coupe and Cabriolet models. Mercedes has achieved six-cylinder-like performance with lower fuel consumption by fitting the new engine with a 48-V electrical system that debuted on the 2017 Mercedes S-Class.

A successful test has seen Rolls-Royce claim the world record for the world's most powerful aerospace gearbox​ with its Power Gearbox. Capable of handling the power from around 400 regular family cars, it will form a key part of Rolls-Royce's next-generation UltraFan engine.

Car makers haven't given up on internal combustion yet. Along with a push towards downsized turbo power, some of the smartest engineers in the world are using new techniques to make their engines more efficient. Here are a few of the most interesting modern takes on the internal combustion engine.

Car manufacturers are delving deep into their boxes of tricks to make internal combustion engines more efficient. Infiniti has a variable compression ratio engine, but Mazda has a different solution. It's set to release the first commercial compression-ignition gasoline engine, dubbed SkyActiv-X.
