It is part of GM’s 5th-generation Small Block engine design that’s named EcoTec3 in pickup trucks, replacing the 4th-generation Small Block engine family known as Vortec. The launch of the EcoTec3 engine line, including the 4.3L V6 LCV, coincides with the launch of the all-new 2014 Chevy Silverado and 2014 GMC Sierra.
Weighing in at 450 lbs (203 kg), the V6 EcoBoost is the daddy of power and performance. It displaces 3,496cc, has a 60 degree layout, a 92.5mm bore and a 86.7 mm stroke. It uses two Honeywell-Garrett GT15 and replaces small-block V8 like a charm. The first time it was previewed was a Lincoln MKR concept where it was rated at 415 hp.
It’s power output is either 355 hp (265 kW) in the case of models like the Lincoln MKS, MKT and Ford Fusion or 265 hp (272 kW) offered by two performance models with tweaked exhausts, the 2013 Ford Explorer Sport and the 2013 Ford Taurus SHO. All these cars have the same torque levels, 350 lb-ft (475 Nm) available at 5000 rpm, though the Ford F-150 pickup gets 420 lb-ft (569 Nm) which is available from just 2500 rpm.
The big question for GM in truck wars is how the counter this Ford powerhouse. They either have to drop the Twin Turbo Cadillac motor or bolt on an eton on the 4.3 Liter.
an Eaton is the probably the best way for GM to bring big bang to the table with a cost advantage.
