Altair and the Center for Automotive Research (CAR) announced the winners of the 5th annual Altair Enlighten Award, which strives to promote and celebrate innovation in automotive lightweighting. The winner of the Full Vehicle category was the 2017 Chrysler Pacifica, which is 249 pounds (113 kilograms) lighter than its predecessor.

Toyota’s carbon fiber closure panels for the 2017 Prius Prime and Lexus LC500 (earlier post), and Faurecia’s Adaptive Valve for exhaust systems employed on the 2017 Chevrolet Silverado took the top honors for the module category. Swedish metal forming specialist A P &T claimed the Enabling Technology category for its innovative aluminum forming technology used on several European vehicles.

2017 Chrysler Pacifica. The FCA team built the 2017 Chrysler Pacifica from the ground up to achieve a lighter vehicle with improved safety, better NVH performance and superior interior space and comfort. The body system, which shed 168 pounds (76 kilograms), utilized high strength steels and large amounts of dual phase and hot stamped material grades for improved impact protection at reduced weight.

Among the innovative aspects of the new Pacifica’s design is its tailor-welded-blank door structure, which utilizes ultra high-strength hot-stamped steel, and its hydroformed loadbeams, also made from ultra high-strength steel. These and other advances enhance crashworthiness and contribute to torsional stiffness that is 88% greater than that of the vehicle it replaces.

In addition, the all-new Pacifica minivan also makes strategic use of aluminum. Its hood and sliding doors are made of the lightweight material.

Further, the Pacifica’s liftgate comprises an aluminum outer panel bonded to a cast-magnesium inner panel—one of the largest cast-magnesium automotive components in high-volume production. The combination of the two materials contribute to weight savings of 18.5 pounds per vehicle.

Simulation methodologies including topology optimization studies were used throughout the vehicle’s development to ensure a material efficient design.

Weight reduction is a key contributor to improved fuel economy. In highway driving, the 2017 Chrysler Pacifica earns a best-in-class rating of 28 miles per gallon (mpg) from the US Environmental Protection Agency (EPA). Its combined city/highway rating of 22 mpg is unsurpassed in the minivan segment, while the all-new vehicle’s unique construction also benefits the 2017 Chrysler Pacifica Hybrid. (Earlier post.)

With an EPA rating of 84 miles-per-gallon-equivalent (MPGe), the Pacifica’s plug-in, electrified twin is the most efficient minivan yet.

Congratulazioni agli admin.

Metalli sapientemente lavorati, geometrie giuste e leghe leggere dove serve, senza dover usare roba esotica

si chiama buona progettazione, al contrario di certi cubetti di duralluminio che pesano come  il cemento.

citofornare Jaguar?

Peccato che questo bel trofeo se lo tireranno in fronte un bel po': sbaglio o questa Pacifica arranca vistosamente nelle vendite?

parrebbe di si: finita anche li la moda dei van a quanto dicono. Peccato, pare un buon prodotto

Al contrario. Le vendite vanno per il momento più che bene; certo sta mediamente un 20% sotto il Town & Country ma è inevitabile. La Pacifica mediamente costa molto di più del T&C; il mercato deve ancora pienamente abituarsi ai nuovi livelli di prezzo, motivo per cui hanno mantenuto il Gran Caravan, che dà altresì la possibilità ad FCA di garantire una soluzione alle flotte e quindi mantenere su buoni livelli il resale value della Pacifica. La quota retail di quest'ultimo è al momento oltre l'85%

ma non avevano sospeso la produzione?
