EVERYBODY CAN MAKE A CAR STABLE WITH A SERIES OF SENSORS AND A SOFTWARE... BUT ONLY FEW KNOW HOW TO MAKE A REALLY STABLE CAR THAT HOLDS THE LINE WITHOUT ELECTRONICS INTERVENTION... HYUNDAI SURELY FOUND A WAY TO DO SO WITH THE SIMPLEST SUSPENSION SYSTEM IN THE MARKET
Since 2010 in Europe they do a Mandatory Stability Test on all the Cars... the test consists in a quick lane Change simulated at 100Kph (about 60mph) where a Computer controlled Vehicle turns the wheels 45 Degrees in a quick movement and then turns it back the other way to put the car straight on the other lane.
The maneuver is done wrongfully on purpose to simulate the average driver which tendentially releases the throttle rather that holding it down... off course there results can change a lot of the throttle is properly pressed during the maneuver.
The Test calculates how much the Car spins out of the desired line... 50% means the car did a 100 degrees turn, 0% means 200 degrees turn (basically the car has done more than a U turn)... off course if a Car spins on itself over 180 degrees, we can easily consider it out of control... 100% is the perfect lane change, with no Slipping at all.
The result is calculated on the differential of percentage between the Test with the ESC OFF and ESC ON... the bigger the difference, the worst is the grade.
It's easy to notice how Cars that use a more Sophisticated Suspension Geometry get a better result than who uses Simpler Geometries and let's the Electronics make up for it... but the Veloster sure broke this rule!
In Europe it's not a news that German Cars are not that stable as they claim here in the US, but you also need to keep in mind that in Europe the average suspensions rating is much harder than what is standardly offered here in the US.
Here are some of the Videos of the TESTS... too bad it's becoming hard to find the full tests Videos of newer cars, anyway... that gives a good idea of the Veloster... despite the "NOT Good Suspensions" it obtained a pretty good result... i wonder what it could have obtained with a nice Double Crossed Links at the Front and MultiLink 5 at the Rear...
DUE TO FORUM REGULATIONS, I CAN ONLY POST 5 VIDEOS, SO I WILL POST THE ONES THAT ARE MORE SIGNIFICANT AND I WILL POST JUST THE RESULTS FOR THE OTHERS... I CAN PROVIDE THE VIDEOS UPON REQUEST
Chevy Malibu
ESC OFF = 16%
ESC ON = 71%
Audi A4
ESC OFF = 18%
ESC ON = 71%
Chevy Cruze
ESC OFF = 21%
ESC ON = 74%
BMW 5
ESC OFF = 14%
ESC ON = 92%
Toyota Prius
ESC OFF = 17%
ESC ON = 86%
bmw 3
ESC OFF = 18%
ESC ON = 88%
Honda Jazz (= Fit with NO Sport Package)
ESC OFF = 26%
ESC ON = 71%
Honda CRZ
ESC OFF = 28%
ESC ON = 89%
Hyundai Veloster
ESC OFF = 36%
ESC ON = 73%
AlfaRomeo Giulietta =
ESC OFF = 48%
ESC ON = 83%
Honda Civic =
ESC OFF = 42%
ESC ON = 91%
It does not surprise that Alfa Romeo is unbeatable when it doesn't use the Stability Control, in fact Alfa uses a pretty complex Suspension Geometry that is seen only is some Supercars like Ferraris, Masteratis, Lamborghini and other similar... i personally have owned 2 Alfas in Italy, and the handling is incredible... the Front Suspension Geometry is a "High Quadrilateral" and ALfa is the only company that adopts this Geometry at the Front, which combined with a MultiLink 5 at the Rear give the amazing handling that Alfas are capable of, but on the down side... if you hit a Speed bump @ 10mph... you have already send the Steering Off Balance and you have 2 grand worth of damages... but the feel while you drive it in is incredible.
That said, it is amazing to me how the Hyundai Veloster can perform so good with such a simple Suspension Geometry such as a McPherson Strut at the Front and a Torsion Beam at the rear... really, the simplest ever, yet seems to be strongly effective, and for sure the thicker torsion bars on the Turbo improved these results.
