mid-engine
“Mid-engine” means the engine is placed near the middle of the car instead of in the front. That can help the car feel more balanced and easier to steer when you’re driving hard.
twin-turbo V8 hybrid powertrain
This is a V8 engine with two turbochargers, plus an electric hybrid system. The turbos help the engine make more power, and the electric motors add extra push when you accelerate.
Axio-flux motors
Axio-flux motors are a type of electric motor design (an axial-flux layout) where the magnetic forces act along the motor’s axis. This architecture can be compact and efficient, which matters in a hypercar where packaging and weight are critical.
0-100 kilometers an hour
This is the time it takes the car to go from 0 to 100 km/h. Faster times usually mean stronger acceleration when you launch from a stop.
drag reduction system
A drag reduction system is a way to reduce how much the car “pushes through” the air. Here it changes the rear wing settings so the car can grip better when slowing down, but also slice through the air faster on straight sections.
downforce
Downforce is the “pressing down” effect from the air that helps the tires stick to the road. More downforce usually means better grip in turns and when braking, while less downforce can help the car go faster on straightaways.
chip shortage
A chip shortage is when carmakers can’t get enough computer chips. Since today’s cars use lots of chips for electronics and safety, fewer chips can mean fewer cars built and higher prices.
Alliance for Automotive Innovation
The Alliance for Automotive Innovation is an industry group that speaks to the U.S. government on behalf of automakers and suppliers. Here, it’s warning officials about shortages of computer chips that are affecting car production.
memory chips
Memory chips are the parts that help computers store information. If there aren’t enough of them, car electronics can’t be completed as planned, which can slow down production.
AI data centers
AI data centers are big computer buildings that train and run AI programs. They need lots of chips, and that demand can make it harder for carmakers to get the chips they need.
E85 fuel
E85 is a type of fuel made from a mix of regular gasoline and ethanol (alcohol). It has a lot more ethanol than typical fuel, which can help a country use less imported oil.
E20
E20 is a fuel blend that mixes ethanol with gasoline—about 20% ethanol. It’s a lower-ethanol option compared with E85.
axial flux motors
An axial flux motor is a type of electric motor where the magnetic force works along the length of the motor. It can be built flatter and more compact than some other motor designs, which is useful when you want more power without adding much size.
permanent magnet material
Permanent magnet material is the special metal used to make the magnets inside an electric motor. Researchers change the material to help the motor stay strong and stable when it spins very fast.
Mercedes-AMG GT
The Mercedes-AMG GT is a high-performance Mercedes sports car made by AMG. It’s the kind of car people buy for strong acceleration and sporty driving feel.
right to repair
Right to repair means you should be able to fix your own stuff—or choose a shop that can fix it—without the maker blocking you. For cars, it’s about getting the information and access needed to do repairs.
diagnostic codes
Diagnostic codes are the “error messages” your car’s computer saves when it detects a problem. A repair shop can read those codes to figure out what’s wrong.
control units
Control units are the car’s computer modules that run different systems. When the car needs a software update, those computers may need to be reprogrammed.
calibrate safety systems
Calibrating safety systems means making sure the car’s safety features are tuned correctly. After certain repairs or software changes, the car may need to be adjusted so those features work as intended.
thermal dynamic efficiency
Thermal efficiency is how well an engine turns fuel into motion instead of wasting it as heat. Better thermal efficiency usually means you get more driving per unit of fuel.
IC engines
IC engines are the traditional gas/diesel engines that burn fuel. Here, they’re used to generate power so the car can drive farther like a hybrid.
range extenders
A range extender is a small engine used mainly to make electricity so the car can go farther. It doesn’t directly drive the wheels like a normal gas car.
1.5-liter turbos
This means a smaller engine (about 1.5 liters) that uses a turbocharger. The turbo helps the engine make more power and can improve efficiency depending on the design.
2-liter turbos
This refers to a turbocharged engine around 2.0 liters. Changing the engine size can affect how it’s tuned to be efficient, especially when it’s only used to generate power.
thermodynamic efficiency
Thermodynamic efficiency is basically “how much of the fuel energy turns into useful work.” The speaker is saying most engines waste more energy as heat than these newer designs.
stroke-to-bore ratio
It’s a way of describing the engine’s internal shape: how long the piston moves compared to how wide the cylinder is. That geometry can change how the engine makes power—often leaning it toward stronger low-end torque.
350 bar
This is how hard the fuel system pushes fuel into the engine. More pressure can help the fuel spray break up better, which helps the engine burn it more cleanly and efficiently.
EGR
EGR means the engine reuses some of its exhaust gases instead of sending all of it out the tailpipe. That helps keep combustion temperatures under control and can reduce certain harmful emissions.
variable-vane turbocharger
It’s a turbo that can adjust its internal airflow. That lets it build boost more quickly when you need it and stay responsive as engine speed changes.
variable-displacement oil pump
This oil pump can adjust how much oil it sends where it’s needed. The goal is to reduce wasted effort while still keeping the engine properly lubricated.
DLC or diamond-like carbon coatings
DLC is a super-hard coating used on engine parts. It helps reduce friction and wear, so the parts can last longer and the engine can run more efficiently.
compression ratio
Compression ratio is how much the engine squeezes the air-fuel mixture before ignition. Squeezing more can make the engine more efficient, but it has to be managed carefully to avoid knocking.
E-rev engines
“E-rev” describes an engine that’s designed to run within a tighter RPM range instead of spinning across a wide range. That can make it easier to run efficiently and use exhaust gas recirculation effectively.
Shenzhen
Shenzhen is a big city in China. The city is trying new rules for how EV insurance is priced, and the show suggests other places could copy it.
mileage
Here, mileage means how much you drive. The insurance plan uses it to charge more if you drive more, instead of charging everyone the same flat amount.
smart technology
“Smart technology” in cars usually refers to driver-assistance and connected systems (like sensors, automated braking, and other ADAS features). Insurance payout rules can get tricky when crashes involve these systems because liability may depend on whether the technology was functioning as intended.
