The commercial teasingly titled “Pitch,” Lexus employed a renowned physicist from a leading university to help determine which type of champagne glasses have the same frequency as the LFA’s revving engine. (The pitch of the glass needed to precisely match the pitch of the engine in order for the flute to shatter.) Lexus racecar driver Scott Pruett then “drove” on the dynamometer until the engine revved to 7,000-9,000 rpm-creating just the right frequency of vibration to break the glass. And, yes, the entire crew wore earplugs during filming.
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.
It’s not the first time Lexus has used champagne glasses in an ad. Now an almost iconic expression of the brand’s pursuit of perfection and pioneering innovation, they were originally used in the brand’s launch commercial in 1989. In one of the most memorable TV spots in history, the new LS sedan revved to high RPMs as a pyramid of champagne glasses was carefully stacked on the car’s hood. As the speedometer approached top speeds, champagne was poured into the top glass and elegantly flowed into the glasses below-without spilling a drop or razing the pyramid.
Most recently, in a 2006 commercial, the ground-breaking park assist feature on the LS 460 was engaged to dramatically and precisely parallel park the vehicle between two giant pyramids of champagne glasses-without touching a glass.
“Pitch” can be viewed at YouTube.com/lexusvehicles. It will air primarily on Americas cable television and during sporting events such as the 2010 Major League Baseball All-Star Game and the USGA U.S. Open Championship. A 3-D version of the spot will play in theaters beginning July 2 to coincide with the debut of a 3-D summer blockbuster.
