How, you may wonder, do dynamics engineers determine what kind of hardware to use in a suspension? Here’s the short version: Other people tell them. Engineers must work within the constraints of the basic suspension arrangement dictated by packaging requirements, budget, and the vehicle architecture. But there’s plenty of tweaking to be done: After collecting benchmark data from the kinematics-and-compliance machine, engineers define a set of K&C targets for their car. They then collaborate with suspension designers to create front and rear geometries that mimic those attributes, altering mounting points, bushing stiffness, link and arm design, and other variables. Here are the five most common suspension configurations found in today’s vehicles:

  2017 GMC Acadia V-6 FWD Makes more sense without the high-zoot badge.While this surely is working out well for GMC profit margins, not everyone can afford to plunk down that kind of cash on an SUV or a truck. So let us present this significantly cheaper Acadia SLT, the next step down the pecking order from Denali, with front-wheel drive, far fewer options, and significantly less flashy trim inside and out. It stickered at a far less ambitious $40,765.

Here are the five most common suspension configurations found in today’s vehicles Put simply, multilink suspensions offer the most separation between handling and ride-quality attributes to reduce compromises.

Solid/Live Axle© Provided by Car and Driver Solid/Live Axle Using the axle housing to locate the wheels is as durable as the idea itself, which is why this ox-cart technology persists in off-roaders, pickups, and commercial vehicles. The obvious flaw: a bump at one wheel also excites the opposite wheel. When a solid axle connects two driven wheels—also known as a “live axle”—the axle shafts, differential, and housing all contribute to unsprung weight, affecting ride quality and aggravating axle hop under acceleration and braking, particularly in high-torque vehicles.

Control Arms© Provided by Car and Driver Control Arms A pair of lateral arms, sometimes called double wishbones or A-arms, offers better control over the kinematics than a strut-type arrangement. Among the benefits: an upper arm that’s shorter than the lower arm to optimize the orientation of the tire contact patch as the body rolls, increasing lateral grip. Control arms also require less height than a strut suspension—the better to slip under the low hoods of sports cars such as the Acura NSX and the Chevrolet Corvette.

Multilink© Provided by Car and Driver Multilink The greatest sophistication and tuning flexibility comes from using a combination of links and arms, or just five individual links. One common arrangement includes three lateral links for side-to-side wheel location, one longitudinal link for fore-aft restraint, and a toe-control link that effectively makes minute steering adjustments as the suspension strokes. The multilink approach allows for higher lateral stiffness and the desired toe change with appropriate vertical and longitudinal compliance. Multilink setups can also be designed to better resist dive and squat under braking and acceleration, respectively. Put simply, multilink suspensions offer the most separation between handling and ride-quality attributes to reduce compromises.

Torsion Beam© Provided by Car and Driver Torsion Beam Frequently found at the rear of economy cars, this arrangement uses trailing arms integrated with a crossmember that is designed to twist as the wheels move. While the torsion beam or “twist beam” isn’t as compromised as a solid axle, neither is it a truly independent suspension. Stiffer bushings can compensate for the torsion beam’s inherent side-to-side compliance, but that comes with a toll of greater impact harshness. (Some vehicles use a Watt’s linkage or a Panhard rod to improve lateral stiffness without compromising ride quality.) Low mounting points along with springs and dampers that are mounted farther outboard than in other arrangements create more interior and cargo space.

The Lexus CT200h Is Dead: Hybrid Hatch Won't Return for 2018

  The Lexus CT200h Is Dead: Hybrid Hatch Won't Return for 2018 <p>The Lexus CT200h has reached the end of the line.</p>We're not too surprised by this news, given the CT's age and dwindling sales numbers. Lexus sold just 8903 copies of the CT200h in 2016, a fraction of the sales numbers enjoyed by other entry-luxury models such as the Mercedes-Benz CLA-class (25,792) and the Audi A3 (31,538) during the same time frame. The CT200h's hybrid drivetrain, shared with the previous-generation Toyota Prius, had also started to look outdated, with its 42-mpg EPA combined fuel economy far outclassed by the latest Prius and its 52-mpg rating.

Here are the five most common types of suspensions . Never wondered how engineers determine and select what type of suspension needed in the car and what materials should be used in production of this suspension ?

Strut© Provided by Car and Driver Strut In this, the most popular front-suspension setup, a beefed-up damper (typically with a concentric coil spring) serves double duty, acting as a locating device while calming vertical movement. Strut configurations are commonly chosen for their simplicity and cost, and they’re narrower than control-arm and multilink arrangements, making them ideal for transverse-engine cars. However, the strut design limits an engineer’s options to optimize camber as the wheel moves vertically.

2017 Jaguar F-Pace 20d Diesel .
Slinky, sporty, sleek . . . and fuel-sipping.When the F-Pace launched last year, the 2.0-liter turbo-diesel model (labeled 20d) anchored the bottom of the SUV’s price ladder. (For 2018, the name 25t denotes a new base engine, a 2.0-liter gasoline turbocharged four.) Jaguar enters the diesel market at a time when most others are exiting it; BMW’s X3 diesel disappeared from the lineup recently, Mercedes-Benz has given up on EPA certifying all of its diesel models for the time being, and we all know what happened to kill off Audi’s Q5 diesel.
