It is a premium, technologically advanced suspension design that  improves ride and handling characteristics in four significant ways:<\/p>\n<\/div>\n<ul>\n<li>Reduces torque steer<\/li>\n<li>Improves vehicle sensitivity to tire      irregularities and  wheel imbalance<\/li>\n<li>Provides more linear and communicative      steering through  improved camber control<\/li>\n<li>Improves impact isolation on bumps and      rough surfaces.<\/li>\n<\/ul>\n<p>Derived from \u201cHigh Performance Strut,\u201d the LaCrosse CXS\u2019 HiPer Strut  suspension is partnered with conventional dampers when used with the  standard 18-inch wheels and an advanced electronically controlled  damping system with the available 19-inch wheels.<\/p>\n<p>\u201cHiPer Strut helps reduce torque steer and maintain negative camber  during cornering,\u201d said Jim Federico, chief engineer for Buick LaCrosse.  \u201cThat improves ultimate grip levels in dry and wet conditions, as well  as improves the direct feel of the road, while isolating undesirable  feedback. Behind the wheel the driver experiences reduced torque steer,  improved grip and increased cornering power, along with crisper  handling, steering precision and feedback.\u201d<\/p>\n<p><a href=\"http:\/\/caddyinfo.com\/wordpress\/wp-content\/uploads\/2010\/03\/X10AR_BU002.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-6718\" title=\"2010 Buick LaCrosse CXS HiPer Strut Front Suspension Exploded Vi\" src=\"http:\/\/caddyinfo.com\/wordpress\/wp-content\/uploads\/2010\/03\/X10AR_BU002-1023x767.jpg\" alt=\"HiPer Strut Front Suspension Exploded View\" width=\"1023\" height=\"767\" srcset=\"http:\/\/www.caddyinfo.com\/wordpress\/wp-content\/uploads\/2010\/03\/X10AR_BU002-1023x767.jpg 1023w, http:\/\/www.caddyinfo.com\/wordpress\/wp-content\/uploads\/2010\/03\/X10AR_BU002-500x374.jpg 500w\" sizes=\"auto, (max-width: 1023px) 100vw, 1023px\" \/><\/a><\/p>\n<p>HiPer Strut is based on the MacPherson strut front suspension design  and features dual-path top mountings that separate the transfer of  spring and damper loads to the body structure. A combined steering  knuckle\/strut carrier is unique to the design. The lower control arms  are attached to a rigid sub-frame that is bolted to the body structure  with four isolators that reduce the transmission of noise and vibrations  to the interior.<\/p>\n<p>The design is also an enabler for a limited-slip differential, for  even greater traction, and supports better ride quality with  larger-diameter wheels \u2013 including LaCrosse CXS\u2019 available 19-inch  wheels.<\/p>\n<p>\u201cPerhaps the most significant attribute of HiPer Strut\u2019s  effectiveness is what you <em>don\u2019t <\/em>feel,\u201d said Federico. \u201cYou don\u2019t  feel torque steer; you don\u2019t feel tugging or vibrations through the  steering wheel; you don\u2019t feel sharp reactions to bumps and pot holes.  You simply experience a smoother, more controlled and more linear  driving experience.\u201d<\/p>\n<p><strong>The foundation<\/strong><\/p>\n<p>The LaCrosse\u2019s stiff body structure is the foundation for more  precise suspension tuning and the CXS\u2019 HiPer Strut design. It is  constructed with ultra high-strength steel strategically placed to  enhance strength, as well as crash protection. LaCrosse CX and CXL  models use a conventional MacPherson strut front suspension.<\/p>\n<p>At the rear suspension, the CX, CXL and the CXS model with 18-inch  wheels feature a four-link design that is mounted to the body at four  points. CXS with optional 19-inch wheels and Touring Package feature a  more sophisticated H-arm design that uses the same attachment points as  the four-link system but with the cross member attached via isolated  mounts. The lower H-arm replaces the basic trailing link, delivering a  greater ride quality and lower noise.<\/p>\n<p>The Touring Package also includes real-time damping and Sport Mode  Selectivity, which uses four electronically controlled dampers to  constantly \u201cread\u201d the road and make adjustments within milliseconds.<\/p>\n<p><strong>Vehicle control<\/strong><\/p>\n<p>Along with HiPer Strut suspension in the CXS, all LaCrosse models  employ a variety of state-of-the-art systems that enable exceptional  vehicle control through the steering system, brakes and more. GM\u2019s  StabiliTrak electronic stability control system is standard on all  models. Additional highlights include:<\/p>\n<ul>\n<li><strong>Variable      effort power steering<\/strong> that delivers  greater assistance      at low speeds, such as parking maneuvers, and  reduced effort at higher      speeds for a greater feeling of control.  The steering system has a quick,      15.2:1 ratio, requiring only 2.75  turns lock to lock.<\/li>\n<li><strong>Four-wheel      disc brakes with four-channel ABS<\/strong>,  including large, 12.6-inch-wide      (321 mm) front discs and  12.4-inch-wide (315 mm) solid rear discs.      Lightweight,  aluminum-body calipers are used at each corner.<\/li>\n<li><strong>Electronic      Brake force Distribution <\/strong>that ensures  optimum      braking force is applied simultaneously at both axles, for  maximum      stability under heavy braking; and a <strong>Brake      Assist  System <\/strong>that senses the severity of a braking situation and       applies additional braking pressure when needed.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Good news that the Cadillac XTS has made it through the next gate and been approved for production in 2011 as a 2012 model.\u00a0 Perhaps it will also benefit from this innovative suspension approach implemented on the Buick Lacrosse: Hiper &hellip; <a href=\"http:\/\/www.caddyinfo.com\/wordpress\/hiper-strut-removing-the-disadvantages-of-fwd\/\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":69,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6,197],"tags":[544,545,862],"class_list":["post-6712","post","type-post","status-publish","format-standard","hentry","category-site-info-news","category-xts","tag-fwd","tag-innovation","tag-suspension"],"_links":{"self":[{"href":"http:\/\/www.caddyinfo.com\/wordpress\/wp-json\/wp\/v2\/posts\/6712","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/www.caddyinfo.com\/wordpress\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.caddyinfo.com\/wordpress\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.caddyinfo.com\/wordpress\/wp-json\/wp\/v2\/users\/69"}],"replies":[{"embeddable":true,"href":"http:\/\/www.caddyinfo.com\/wordpress\/wp-json\/wp\/v2\/comments?post=6712"}],"version-history":[{"count":10,"href":"http:\/\/www.caddyinfo.com\/wordpress\/wp-json\/wp\/v2\/posts\/6712\/revisions"}],"predecessor-version":[{"id":6724,"href":"http:\/\/www.caddyinfo.com\/wordpress\/wp-json\/wp\/v2\/posts\/6712\/revisions\/6724"}],"wp:attachment":[{"href":"http:\/\/www.caddyinfo.com\/wordpress\/wp-json\/wp\/v2\/media?parent=6712"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.caddyinfo.com\/wordpress\/wp-json\/wp\/v2\/categories?post=6712"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.caddyinfo.com\/wordpress\/wp-json\/wp\/v2\/tags?post=6712"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
