Powered by a supercharged 4.2L V8 engine, JE Design’s Audi A8 (500hp/443 lb-ft) rockets to 60mph in just 5.2-seconds and has a top speed of 188mph. Cosmetic enhancements include side sills with air intakes, an additional lateral ventilation channel, a rear spoiler, and 21-inch two-piece wheels. Few more images after the jump. [via SeriousWheels]
