Engine Specs for Vehiclesby Contributing Writer
Vehicles the Vehicles division of Vehicles Motors, released three pickup Vehicles with the Vehicles C/K nameplate in Vehicles.
Under The Hood:
- Engine Specs for the BMW 323i 2.5 Liter
- Engine Specs for a 2001 Ford 5.4L
- Engine Specs for a 1994 GMC Sierra
- Engine Specs for the 5.3 Vortec
- Engine Specs on a 2.5 Liter Jeep
The BMW 323i's 2.5 liter has six cylinders in a direct line, known as an in-line six-cylinder (I-6). This I-6 engine has 24 valves---four per cylinder---in a double overhead cam (DOHC) configuration.
The 2.5-liter I-6 has a bore (cylinder width) of 3.31 inches, a stroke (distance piston travels in the cylinder) of 2.95 inches and a compression ratio of 10.5 to 1. The 2.5-liter has a total displacement of 2,494 cubic centimeters.
As with all BMW engines, maximum power is a focus point of the 2.5-liter. The 1998 incarnation of this engine produces 168 horsepower at 5,500 revolutions per minute (rpm); the 1999 and 2000 versions produce 170 horsepower at 5,500 rpm. All three years' models, produce 181 foot-lbs. of torque at 3,500 rpm.
When combined with an automatic transmission, the 2.5-liter can go 19 miles per gallon (mpg) in the city and 27 to 28 mpg on the highway. This engine can travel 19 to 20 mpg in the city and 28 to 30 mpg on the highway when coupled with a manual transmission.
The basic 5.4-liter V8 produces a respectable 260 horsepower at 4,500 rpm and 350 foot-pounds of torque at 2,500 rpm. It has an engine displacement of 5,408 cc, a compression ratio of 9:1, a 3.55-inch bore and a 4.16-inch stroke. The 5.4 came standard with several trim packages, including the Lariat, the SVT Raptor SuperCab and the XLT Super Crew.
Strictly for Ford's hot-rod F-150, the SVT Lightning, the supercharged version of the 2001 5.4-liter engine provided massive power, lending credence to the specialty truck's name. Ford's Specialty Vehicle Team managed to get 380 horsepower from the engine at 4,750 rpm and a brutish 450 ft-lbs of torque at 3,250 rpm. The Lightning's 5.4-liter plant was outfitted with aluminum alloy heads and a forged steel crankshaft. The motor redlined at 5,250 rpm.
Versions of the 5.4-liter V8 powered many Ford vehicles in 2001, including the Expedition, the Excursion and the Lincoln Navigator SUVs. Ford used versions of the 5.4-liter engine in high-performance cars as well, such as the Mustang SVT Cobra R, the GT supercar and the Shelby GT500.
1994 GMC Sierra 1500
Most of the 1994 GMC Sierra 1500 trims have a 4.3-liter V-6 that generates 165 horsepower and 236 pound-feet of torque, with a 4,293-cubic centimeter displacement, a bore and stroke of 4-by-3.48 inches and a 9.1-to-1 compression ratio. Two of the trims have a more powerful option: a 5-liter V-8 with 175 horsepower, 275 pound-feet of torque, a 5,001-cubic centimeter displacement, a 3.74-by-3.48-inch bore and stroke, and the same compression ratio as the 4.3-liter V-6 engine.
1994 GMC Sierra 2500
The 1994 GMC Sierra 2500 vehicles have the same two engine choices as their smaller 1500 siblings. They also have a third option: a 5.7-liter V-8 that generates 190 horsepower and 300 pound-feet of torque. Additionally, it has a 5,737-cubic centimeter displacement and a 8.6-to-1 compression ratio, with the same bore and stroke as the 4.3-liter V-6 engine.
1994 GMC Sierra 3500
Unlike its smaller contemporaries, the 3500 version of the 1994 GMC Sierra offers only one standard engine: the 5.7-liter V-8, the same as the most powerful engine offered for the Sierra 2500.
Bore and Stroke
The 5.3-liter V8 has a bore of 3.78 inches and a stroke of 3.62 inches. Bore is a measure of the diameter of the engine's eight cylinders, and stroke is the distance that the pistons, which are housed in the cylinders, travel when the engine is operational.
The 5.3-liter Vortec engine has compression ratios from 9.5 to 1 and 9.9 to 1. These high compression ratios mean that the engine can produce between 270 and 300 horsepower at around 5,200 revolutions per minute (rpm) and 315 to 325 foot-pounds of torque at 4,000 rpm, making it a popular engine for performance- and work-oriented consumers.
The 5.3-liter V8 appeared in a variety of GM-branded vehicles. In 1997 the manufacturer remodeled the engine, placing it in such vehicles as the Chevy Tahoe and GMC Sierra beginning in 1999, and the Chevrolet Colorado beginning in 2009.
The AMC-developed 2.5L inline four-cylinder engine in the Jeep Wrangler is a naturally aspirated eight-valve OHV design. This motor has a 3.88-inch bore, 3.19-inch stroke and a compression ratio of 9.2:1. This powerplant produces 120 horsepower at 5,400 rpm and 140 ft-lbs of torque at 3,500 rpm.
Payload and Towing
The 2.5L-engined Wrangler is capable of the same payload and towing capacities as the 4.0L inline six-cylinder engine. Maximum towing for this vehicle is 2,000 lbs, while maximum payload is rated at 800 lbs.
The 2.5L four-cylinder motor yields 16 mpg city and 18 mpg highway when mated to a three-speed automatic while the five-speed manual yields 18 mpg city and 20 mpg highway.
