I have witnessed a rare event a quantum leap by General Motors.

Eight years ago, I was in Newfoundland for the launch of the then-new Chevrolet Silverado and GMC Sierra.

Last week, I was in the Maritimes to drive the newest light-duty editions of the popular pickups.

What a difference.

These new trucks are infinitely better, a point driven home in a comparison handling test between the new models and the current offering.

The new rack-and-pinion steering responds quickly and the new suspension system cuts down on understeer and keeps the wheels securely on the ground in quick, tight cornering.

The new vehicles are stronger, bigger, roomier, safer and more powerful.

Although there are still a number of similarities between GMC and Chevy, there's a greater differentiation between the two and even between interiors of the 'work' and 'play' editions in each brand.

Beneath new sheet metal is a stiffer frame, giving the vehicles a wider track.

Fit and finish are considerably better, with much tighter tolerances in body gap, along with a 50% reduction in gap from cab to box.

Speaking of the box, it is stronger, with a one-piece wheelhouse and inner box side that eliminates those 'pencil' support braces of previous trucks.

If you need a locking tailgate, that's available, too, and it comes with a lift-assist mechanism.

Rear doors on extended cab models open 170 degrees for easy loading.

And here's a bonus in the Sierra for folks who always seem to end up in back: Fully-opening power windows on the access door.

The biggest similarities are in powertrains: 195-hp, 4.3-L V6; 295-hp, 4.8-L V8; 315-hp, 5.3-L V8; 367-hp, 6-L V8; and a Sierra Denali-exclusive 400-hp, 6.2-L V8.

All are connected to a four-speed automatic transmission, with the exception of the 6.2-L, which gets a new six-speed automatic.

Trucks on the launch were powered by 4.8-, 5.3- and 6-L V8s and none were lacking in power.

All have excellent throttle response and strong torque curves. The 5.3 and 6.0 engines come with Active Fuel Management -- GM's name for cylinder deactivation, a system that makes a seamless transition from eight cylinders to four and back to eight depending on throttle demand.

While the four-speed automatic transmission with tow/haul mode is good, a five-speed automatic would smooth out the remaining rough edges in shifting under full throttle.

Ride comfort varies depending on which of the five suspension packages you choose and whether the truck is two- or four-wheel-drive, but in any case it's better than before -- and quieter -- although it's impossible to eliminate wind noise from around the massive mirrors.

On the safety side, StabiliTrak stability control with rollover mitigation is standard on crew cabs and optional on extended cabs as is tire-monitoring system. Park assist is also available.

There are also enough standard optional air bags to cover any situation.

As for power, trailering capability has been boosted 4,600 lb. (2,091 kg) to 10,500 lb. (4,773 kg) with NHT trailering package. Payload is 2,160 lb. (982 kg).

Pricing?

MSRP begins at about $23,370 (regular cab, standard box 2WD) and tops out at roughly $46,000 (crew cab, short box 4WD).

And you can always run the tag higher with options and accessories.
