Cadillac has aggressively used light materials for its recently-launched new cars, but for the all-new C1 architecture underpinning the XT5 crossover, engineers stuck with steel—and still achieved a major weight reduction.
Packing a 640-hp supercharged LT4 V8 under its muscular, CFD-designed hood, Cadillac's new performance flagship strikes many developmental balances, said Chief Engineer Tony Roma.
To equip its flagship sedan for the challenge, Cadillac designers and engineers have built the CT6 on a unique vehicle architecture, an aluminum-intensive body structure that is fully one-third steel. Twenty-one patents are pending for the new full-size, rear-wheel-drive, transverse-engine configuration, a variation of GM’s Omega II platform.
GM's all-new premium flagship sedan is about 200 lb (91 kg) lighter than the BMW 5 Series but offers the interior volume of the short-wheelbase 7 Series, thanks to what is arguably the industry’s most aggressive combination of lightweight materials, forming technologies, and new joining methods in a non-exotic sedan.
With nine other states as allies, California's zero-emission vehicle mandate covers almost 30% of the U.S. car market. Hybrids and PZEVs no longer count toward ZEV credits. Battery electric vehicles with range extender engine/generator systems are key technologies to meet new regulation.
Foreign materials like dust, mud, road salt, snow and other related debris can cause lens or sensor obstruction that will lead to degraded or non-functional system performance.
Imetrum’s precision, noncontact 3D measurement system, the Precision Displacement Tracker, slashes setup times and provides richer data sets without compromising measurement resolution or sampling speed.
With its newest work space designated a center of excellence for cameras, ZF TRW underscores the critical role 'seeing' technology plays in automated driving.
