Holden has inhabited the Lang Lang proving grounds for nearly 60 years, and it will continue to locally develop and hone global product here for the foreseeable future, even after local manufacturing fizzles out.
Plenty goes on at Lang Lang, which features over 14 miles of closed roads for testing, and nearly 12 miles of dirt roads for SUVs, crossovers and pickups. But, there’s a fun secret that hides on the 2.91 mile oval test course.
Holden has implemented three lanes on the oval course, ranging from flat, to inclined gradients. The lower two lanes are standard, but the third, upper lane hides a nifty secret, according to Business Insider, which had a chance to sample the Easter egg of sorts.
No matter the vehicle, body style or engine, once the vehicle reaches 100 mph, it can drive itself in this third lane. The gravity begins pushing the car towards the middle around the track, and wind resistance from the bottom keeps the vehicle up.
So, yes, it’s completely possible to take one’s hands off the steering wheel and hold speed at 100 mph exactly. The car will run the oval flawlessly until it runs out of fuel.
We’re not sure how Holden came to this conclusion, but we’d say it’s a marvelous engineering feat nonetheless, and one we’d love to try some day.
