Lexus challenges passengers to control their heart rates... in a hybrid

Picture the scene: You're in a quiet place; a forest. The grass is green, the sky a perfect shade of blue. It's sunny; the temperature is hovering somewhere near perfect and a gentle breeze wafts by. You look at the pretty flowers – bend down to reach one... then, BAM!

No, we're not talking about Bambi versus Godzilla – though we do offer Marv Newland a healthy round of applause. What's we're talking about is the Lexus GS Hybrid. Or, more specifically, the car's Italian advertising campaign as seen in the video below.

Lexus claims its 2013 GS 450h can accelerate from 0 to 60 mph (96 km/h) in just 5.6 seconds, courtesy of its 3.5-litre V6 engine and electric motor hybrid powertrain that puts out a combined 338 horsepower. Combine that level of thrust with rear-wheel drive and a professional driver and you've got yourself some fun at the race track.

Lexus decided to put this combination together, mixing in a blend of new-car shoppers to see what effect its hybrid sedan had on the heart.
