Abstract(E)	Battery-powered electric drives are shaping the future of passenger cars, but electrified sports cars face reservations due to a lack of emotion. This article presents a powertrain concept for super sports cars that combines electric drive with combustion engine emotions using a range extender. The Hyper-REEV mode synchronizes engine acoustics with acceleration, offering high emotion and high efficiency. The article analyzes requirements and solutions for Hyper-REEV components, including battery design, e-machines, power electronics, and generator. The combustion engine's role is decisive, showcasing high efficiency and dynamic performance. The final part covers the overall concept and control strategy linked to SDV.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
