I have a 2015 Hyundai Elantra SE. It has 25,000 miles and serves its purpose of a street parked commuter car that is comfortable enough for the occasional 600-mile round trip on weekends. The only real issue I have with the car is the cheap-car torsion beam rear suspension. Over large bumps on one side of the car the rear of the car feels like it oscillates extremely in each direction.

In a straight line it is controllable but I worry that in a off ramp taken a little too fast that a unseen bump could actually upset the car enough to lose control (or surprise a fiancé who is used to the handling of a 200S). The 2007 Honda Fit and 2015 Chevy Volt I drove I believe have similar setups but didn’t feel at all like this, and neither did the 2011 Crown Victoria I drove. I’ve read online that some aftermarket replacement shocks would help with this.

Is this really the case? Would a lighter set of wheels also help?

I was there when Ford debuted its new-for-1999 Mustang Cobra with its “revolutionary” new independent rear suspension. The IRS was a first for the Ford Mustang, and it was a move that Ford’s brass believed would allow the “new edge” Cobra to compete with cars like the BMW M3 for supremacy in the budget super car market. I also remember the very first question that was asked: Will a Ford 9″ bolt in? It was the first question, right out of the box … and it seems like someone at Ford remembers. The new-for-2015 Mustang is going to hit dealers with a new independent rear suspension late next year, and it seems like Ford Racing will have a 9″ live axle option ready.

Sajeev,

The Wall Street Journal recently suggested that part of VW’s problem in the US is the slow growth in Passat sales. About the Passat sales, they attribute it to a cheapening of the components relative to the European Passat, stating: “The American model also got a simpler, lower-cost suspension that delivered a less precise ride.”

My question is: how does one tell a priori that they are buying a car with a cheap suspension? Many mainstream media car reviews do not discuss the objective quality and construction of suspension components, preferring to discuss subjective feelings of ride. In addition, a car’s ride may “feel” good now, but this does not mean that it will in 5 years.
