Mazda hasn't been very exciting lately. There's been some talk about hybrids and efficient engines, but nothing really awesome. Now, a new patent application for an electric supercharged and turbocharged engine makes it look like the crazy old Mazda is back.
It works like a twin-turbo engine, only Mazda's design uses a small electric-driven supercharger that boosts the engines at low revs and then disengages at a specific mid-range RPM point. That's when a variable vane turbocharger kicks in, which opens its blades to gulp in more exhaust as engine speed increases.
BMW is also designing electric compressors, but their system is more like a hybrid and less like a twin-turbo.
While Mazda is struggling financially, they know how to make cool things on a budget, and hopefully we'll see this twincharger technology in production in a few years.
Pictured is a 1993-2002 RX-7, the last exceptionally awesome production car Mazda built. Just to prove my point, they also came with double-boosted engines, in the form a twin-turbo rotary.
