In search of the perfect pitch for the LFA supercar

(June 17, 2010) TORRANCE, Calif.  — It’s a dramatic moment. In an ultra-modern audio studio, a Pearl White Lexus LFA supercar faces its challenger: a lone crystal champagne flute on a pedestal alongside a sleek amplifier. The vehicle’s keyless ignition is engaged, and its rear wheels start spinning on a dynamometer. The engine roars louder and louder, the speedometer clicks past 150, 160, 170 mph. That’s when the glass quivers and shimmies until – kshhh! – the flute shatters in gorgeous slow motion.
 
In this latest commercial from Lexus, which begins airing on June 2, the LFA’s signature engine sound achieves a feat reserved for virtuoso performers. The unique sound of 552-horsepower engine, which helps the vehicle reach top speeds in excess of 200 mph, shatters the glass without the use of CGI or camera tricks.
 
“The glass is actually broken by the precision sound of the vehicle,” said Dave Nordstrom, vice president of marketing for Lexus. “We wanted to show just how deep our pursuit of perfection and commitment to innovation goes. The LFA was designed to deliver its own unique exhaust note, and this illustrates that beautifully.”
 
Lexus worked with a team of engineers to enhance the acoustics of the LFA’s 4.8L engine by meticulously tuning its multi-stage exhaust system. From the elegant, yet understated idle rumble to the goosebump-worthy wail of the high-revving V10 engine, the LFA was deliberately engineered to deliver a sound unlike that of any other road car.
 
After studying the unmistakable soundtrack generated by Formula 1 cars at maximum revs, the team created the signature LFA sound beginning by emphasizing the secondary combustion frequency of the engine and then introducing primary, secondary and tertiary firing harmonics.
 
The note is so unique that Lexus has even created an LFA ringtone that can be downloaded for free at http://www.lexus-lfa.com (click “Digital Premium”).
