General Motors expects its new V-6 engine to increase the demand for the 2014 Chevrolet Silverado and GMC Sierra. The carmaker’s older 195-hp 4.3-liter V-6 loses in towing power and output as well as fuel economy to similar engines in the Ford F-150 and the Ram 1500. The 3.7 liter V-6 in the F-150 provides 302hp while the 3.6-liter V-6 in the Ram 1500 returns 305hp.
GM's new 4.3-liter V-6 now offers 285hp and boasts of higher torque and competitive fuel economy -- 18 city/24 highway – thanks to implementation of advanced technology like direct fuel injection, variable valve timing and cylinder deactivation. GM's new 4.3-liter V-6 also offers the best fuel economy among the similar engines in the three pickups.
GM invested $400 million to retool its Tonawanda site to build the V-6 and three redesigned V-8s, which all belong to the fifth generation of Chevrolet's small-block family.
All the engines are built on the same production line, marking the first time that GM has assembled V-6s and V-8s on the same line. GM fits the 5.3-liter V-8 in pickups and the two versions of the 6.2-liter V-8 for trucks and for the Chevrolet Corvette Stingray. Although the Tonawanda site is one of GM's oldest plants, it is now one of its most advanced.
The site features giant robots lifting unmachined cast engine blocks and placing them in cells in which the bores are honed, cam bearings are pressed in and bolt holes are threaded. The site also features machines that install all the intake and exhaust valve components in about 40 seconds. Another set of machines are in place to measure the surfaces of the block and cylinder heads for imperfections.
According to GM, over 11,000 checks of each engine are done. Tonawanda site manager Steve Finch remarked that GM can build 1,600 engines per day on three shifts. V8s are expected to account for 70% of production.
The 2012 Chevrolet Silverado is taking it up a notch as the segment’s “most capable and diverse lineup” by receiving a couple of upgrades in terms of appearance, comfort and connectivity.
Aside from the new front-end designs, Chevrolet enhances the 2012 Silverado’s appearance and comfort by adding heated/cooled seats (for the LTZ models) and a special White Diamond Edition. A new navigation radio is also installed for better connectivity, while an updated screen and integrated hard drive replace the old discs with map data. Moreover, OnStar and SiriusXM satellite radio are offered exclusively for the Silverado’s segment, inclusive of Bluetooth, USB connectivity and a dealer-installed Wi-Fi system.
To enhance performance regardless of driving and trailering conditions, all Chevrolet Silverado 1500s come with a StabiliTrak electronic stability control system which features a Trailer Sway Control and Hill Start Assist (however, this doesn’t apply for the Hybrid models).
For truck aficionados, the Silverado is very appealing especially because of its very dependable V8 engine, fuel-saving competency, as well as its broad range of models; and because of this, Chevrolet Truck marketing director Maria Rohrer proudly announces the increase in the line’s sales by 7% through July 2012.
According to her, the upgrades and enhancements that the Silverado received for 2012 recreated the rugged concept to a fresher, more updated design (including its navigation radio and Wi-Fi systems), giving it a “more convenient and enjoyable” vibe.
In addition to all that, the new and revised 2012 design features a chrome mesh grille with a matching chrome surround for the LS and LT models and a body-color surround for the LTZ model. Also, take note that the LS and LT models come with a silver-painted lower bumper fascia – said to enhance the aerodynamics of the two-wheel drive models without tow hooks – and fitted with new 20-inch chromed aluminum wheels.
