The Premium V family of automobile engines is General Motors' modern 90° v engine architecture. The family is most associated with Cadillac's Northstar V8, but the family has also seen use at Oldsmobile (as the Aurora L47 V8 and "Shortstar" LX5). The Oldsmobile variants are no longer in production, but the Northstar family has expanded with new longitudinal and 4.4 L supercharged versions. The Northstar name is now used outside Cadillac as well, with the Pontiac and Buick versions now carrying that moniker. Alfa Romeo is rumored to be another future user of the Premium V in the US-market Kamal. Automakers or automobile manufacturers are companies that design and manufacture automobiles. ...

Development and features

The Premium V design was initiated as a response to the advanced dual overhead cam V8 engines introduced by Cadillac's European and Japanese competitors in the late 1980s. At that time, Cadillac was using the aluminum HT family overhead valve V8 with pushrods which had been pushed hastily into production after the failure of the V8-6-4 of 1981. A double overhead cam (also called a dual overhead cam, DOHC, or twincam) engine is a type of internal combustion engine where the camshafts that operate the intake and exhaust valves are mounted above the cylinders, and where there are separate camshafts for inlet and exhaust valves. ...

Cadillac was developing new models like the Allanté and updated Eldorado and Seville STS which they hoped would compete against the best from BMW, Mercedes-Benz, Lexus, and Infiniti. They developed a laundry list of items that must be included in these new models, including sophisticated steering, braking, and suspension technologies, which became known as the Northstar System. One key element was a high-tech V8 engine with all of the features and performance of the competitors' offerings. The Cadillac Allanté was Cadillacs first venture into the luxury roadster market and was sold from 1987 through 1993. ... The Eldorado model was part of the Cadillac line from 1953 to 2002. ...

The "Northstar" V8, as it was then known, was to be an all-aluminum DOHC 32-valve V8 which was capable of producing 300 hp (224 kW). Archrival Ford Motor Company was developing a similar engine at that time as well, and Ford's Modular engine would follow the Northstar into production one year later. Both continue in production at 4.6 L of displacement. A double overhead cam (also called a dual overhead cam, DOHC, or twincam) engine is a type of internal combustion engine where the camshafts that operate the intake and exhaust valves are mounted above the cylinders, and where there are separate camshafts for inlet and exhaust valves. ... In automotive engineering, an engine is referred to as multi-valve (or multivalve) when each cylinder has more than two valves. ... now. ... The Modular engine, or mod motor, is Ford Motor Companys modern overhead camshaft (OHC) V8 and V10 engine family. ...

The Northstar featured a unique die-cast aluminum 90° V8 block with 102 mm (4 in) bore spacing split into unitary upper and lower halves. The lower crankcase assembly supported the crankshaft without conventional main bearing caps. An oil manifold plate with an integrated silicon gasket forms the oil gallery under this.

Cast-iron cylinder liners were specified, sparing Cadillac from the Nikasil fiasco. The forged aluminum pistons included valve clearance, making Northstar a non-interference engine, with bronze pin bushings and free-floating piston pins used. Nikasil is a trademarked electrodeposited oleophilic nickel matrix silicon carbide coating for engine components, mainly piston engine cylinder liners. ...

The one-piece cast aluminum cylinder heads extend around the "maintenance-free" cam-drive chain case. Direct-acting hydraulic valves are used with a lubrication passage drilled through the cylinder head lengthwise. The intake valves are inclined at 25°, while the exhaust valves are canted to 7° with center-mounted platinum-tipped spark plugs. The cam covers were fabricated from magnesium for light weight.

Eight thermoplastic tubes were used in the induction system, leading to sequential fuel injection. Direct ignition was a novelty for the time, with an electronic system adjusting spark and fuel injection timing as well as the shift points for the new 4T80-E transmission. The 4T80 (and similar 4T80-E) is a series of automatic transmissions from General Motors. ...

One notable feature, advertised at the time, was the fail-safe cooling mode which allowed the engine to continue running for a limited time without any coolant at all. It alternated banks of cylinders to maintain cool temperatures, allowing a Northstar-equipped car to be driven with no coolant for about 100 mi (161 km) with no damage.

All engines of this family share the same Northstar bellhousing pattern. Though GM has manufactured many different engines, it has kept variance in the bellhousing patterns to a reasonable minimum. ...

Later developments included variable valve timing, which can vary intake by up to 40° and the exhaust by up to 50°. First introduced in the longitudinal LH2 version, this system later spread to all Northstars. Variable valve timing, or VVT, is a generic term for an automobile piston engine technology. ... In automotive engineering, a longitudinal engine, also sometimes known as a north-south engine, is an internal combustion engine in which the crankshaft is oriented along the long axis of the vehicle, front to back. ...

Northstar

The engine was introduced in mid-1992 in the 1993 Cadillac Allanté and continues to be used in most Cadillac models. The original Northstar Allanté also introduced the Northstar System which included traction control, adaptive suspension, and antilock brakes. 1992 (MCMXCII) was a leap year starting on Wednesday. ... 1993 (MCMXCIII) was a common year starting on Friday of the Gregorian calendar and marked the Beginning of the International Decade to Combat Racism and Racial Discrimination (1993-2003). ...

The Northstar System was Cadillacs trademarked name for a package of automobile performance features. ... Traction control systems, on current production vehicles, are typically (but not necessarily) electro-hydraulic systems designed to prevent loss of traction (and therefore the control of the vehicle) when excessive throttle or steering is applied by the driver. ... An anti-lock braking system (commonly known as ABS, from the German name Antiblockiersystem given to it by its inventors at Bosch) is a system on motor vehicles which prevents the wheels from locking while braking. ...

The Northstar was sold exclusively by Cadillac for over a decade before being introduced in the 2004 Pontiac Bonneville and 2006 Buick Lucerne. However, the L47 V8 variant was used in the Oldsmobile Aurora and the 3.5L LX5 V6 in the Oldsmobile Intrigue. The engine received a forged steel crankshaft in 2003. Cadillac is said to be planning to introduce a V12 Northstar this decade, likely for use in the Escalade. 2004 (MMIV) was a leap year starting on Thursday of the Gregorian calendar. ...

L37

The L37 was the original Northstar. It is tuned for responsiveness and power, while the later LD8 is designed for more sedate use. The L37 code has been used on all high-output transverse Northstars, even as the exact engine specifications evolved. A transverse engine is an engine in which the crankshaft is oriented side-to-side relative to the wheels of the vehicle. ...

The original L37 was specified at 290 hp (216 kW), but 1993 production examples were rated at 295 hp (220 kW). The engine topped out at 300 hp (224 kW) from 1996 through 2002 on the STS and ETC models, making these some of the most powerful front wheel drive cars ever built, the most powerful title still belonging to the 1970 Cadillac Eldorado with 400 hp (500 in³, 8.2 L). 1993 (MCMXCIII) was a common year starting on Friday of the Gregorian calendar and marked the Beginning of the International Decade to Combat Racism and Racial Discrimination (1993-2003). ... 1996 (MCMXCVI) was a leap year starting on Monday of the Gregorian calendar, and was designated the International Year for the Eradication of Poverty. ...

LD8

The LD8 is a transverse V8 for front-wheel drive cars. Introduced in 1994, it is designed to provide more torque than the high-revving L37. The LD8 code has been used on all torque-tuned transverse Northstars, even as the exact engine specifications evolved. A transverse engine is an engine in which the crankshaft is oriented side-to-side relative to the wheels of the vehicle. ...

LH2

The Northstar was designed originally for transverse front-wheel drive applications. It was modified substantially in 2004 for longitudinal rear- and all-wheel drive use in the SRX and XLR. The RWD (LH2) Northstar is good for 315–320 hp (235–239 kW) and 310–315 ft·lbf (420–427 N·m).

Although most of the Northstar's features, including the coolant loss system, remained intact, the decreased bore increased weight unacceptably. To reduce it, Oldsmobile used a one-piece glass-filled thermoplastic intake manifold and simplified AC Rochester sequential fuel injection. A new die-cast structural aluminum oil pan incorporated baffling to reduce oil starvation in hard driving. A starter interlock prevents the starter from engaging if the quiet L47 is already running. Rochester Products Division was a division of General Motors that manufactured carburetors, and related components including emissions control devices and cruise control systems. ...

The LX5 V6 is a DOHC engine from Oldsmobile, introduced in 1999 with the Oldsmobile Intrigue. It was produced by the Premium engine group at GM and was thus called the Premium V6, or PV6, while it was being developed. It is based on the L47 Aurora V8, which is itself based on the Northstar engine, so engineers called it the Short North, though Oldsmobile fans have taken to calling it the Shortstar.

It is not a simple cut-down V8. Although it has a 90° vee-angle like the Northstar and Aurora, the engine block was engineered from scratch, so bore centers are different. It has chain-driven dual overhead cams and 4 valves per cylinder, but is an even-firing design with a split-pin crankshaft similar to the modern GM 3800 engines. The LX5 displaced 3.5 L (3473 cc) and produced 215 hp (160 kW) and 230 ft·lbf (312 N·m). Bore is 89.5 mm and stroke is 92 mm.

The cost of building this engine was high, and it was not used in many vehicles. It was said at the time that a family of premium V6s would follow, with displacements ranging from 3.3 L to 3.7 L, but only the LX5 was ever produced. It was entirely different from any other V6 in the GM inventory, and as with the Aurora V8, production stopped with the demise of Oldsmobile.
