Mas­sive SUV joins sub-six se­conds club

New Zealand LCV - - NEWS | USA – 2017 RAMS -

CHEVRO­LET HAS IN­TRO­DUCED A SPE­CIAL EDI­TION MODEL TO ITS Ta­hoe and Sub­ur­ban full-sized – read very large – SUV ranges, the in­con­gru­ously-named Rally Sport Truck, or RST.

Chevy says the RSTS – on sale from the north­ern hemi­sphere au­tumn – have been stripped of vir­tu­ally all chrome trim to achieve “a street per­for­mance ap­pear­ance.”

The Ta­hoes and Subur­bans get body-colour grille sur­rounds and door han­dles; gloss-black grille and mir­ror caps; and black roof rails, win­dow trim and Chevy bowtie badges. They also have 22-inch al­loy wheels and Bridge­stone P285/45R 22 tyres.

Op­tions in­clude a Borla per­for­mance ex­haust sys­tem which Chevy says im­proves ex­haust flow by 28 per­cent, gain­ing 5kw to 7.5kw at the rear wheels.

Also avail­able is a brake pack­age with mas­sive front red Brembo six­pis­ton alu­minium calipers with brake pads clamp­ing on larger-than-stock 410mm by 32mm Du­ral­ife disc ro­tors.

The brake pack­age has 84 per­cent more pad area and a 42 per­cent in­crease in ro­tor area for in­creased ther­mal ca­pac­ity.

The Ta­hoe RST’S per­for­mance Pack­age in­cludes per­for­mance-cal­i­brated Mag­netic Ride Con­trol, a 6.2-litre V8, and the new 10L80 10-speed au­to­matic trans­mis­sion.

The 6.2-litre V8, which delivers an es­ti­mated 313kw and 624Nm is a first for the Ta­hoe, and has di­rect in­jec­tion, Ac­tive Fuel Man­age­ment and con­tin­u­ously vari­able valve tim­ing.

The all-new 10-speed au­to­matic has smaller steps be­tween each ra­tio to max­imise engine power un­der ac­cel­er­a­tion.

Chevy says pre­lim­i­nary es­ti­mates give the Ta­hoe RST Per­for­mance Pack­age a braked trailer tow­ing ca­pac­ity of 3800kg and ac­cel­er­a­tion to 96km/h in less than six se­conds.

“When you want to hus­tle, (the RST) is in­cred­i­bly fast, with sig­nif­i­cantly higher lev­els of ac­cel­er­a­tion, brak­ing and road-hold­ing grip,” says Chevro­let full-size trucks chief engi­neer, Eric Stanczak. “When you want to re­lax, it is very re­fined, with ex­cep­tional ride com­fort and in­te­rior quiet­ness.”

Chevy’s truck mar­ket­ing di­rec­tor, San­dor Piszar, says the RSTS are de­signed for cus­tomers who want “a street per­for­mance look with­out sac­ri­fic­ing ca­pa­bil­ity or re­fine­ment, along with the op­tion of in­creased per­for­mance...”

High-per­for­mance ver­sion of Chevy Ta­hoe does away with chromed trim.
