2002 Cadillac DeVille: The Last of the Big Guns

The last of the big body Cadillacs

2002 Cadillac DTS

…in the continuing saga of “As the Standard of the World Turns.”

DeVille base 2

The 2002 Cadillac DeVille is one of the last marques of distinction from the brand. At the time…Cadillac existed for an entire century; the name “DeVille” was attached to some of the most dramatic automobiles for well over half of this prominent existence. The Cadillac DeVilles were and still are America’s favorite luxury cars.

The design and engineering for 2002 is sophisticated and highly advanced among luxury automobiles. From the avant-garde styling…to the powerful Northstar V8 under the hood, the DeVille delivers the poised dignity that was the hallmark of every Cadillac. NotoriousLuxury presents the 2002 Cadillac DeVille’s intransigent eminence…in the continuing saga of “As the Standard of the World Turns.”

As Cadillac so eloquently stated: “Enduring style and sophistication is difficult to define…and even more challenging to achieve. But such élan is unmistakable in the Cadillac DeVille.” For the 2002 model year it was available in three distinctive trim levels. 

There is the power and prowess of the DTS (DeVille Touring Sedan) which puts the emphasis on performance as well as presence.  The DHS (DeVille High Luxury Sedan) provides luxury and panache with exclusivity…Cadillac-style. And last but not least…the base DeVille which is the quintessential luxury sedan that satisfies the most discerning buyers who seek automobiles of this stature.

The 2002 Cadillac DeVille unifies elegance with high technology in an automobile designed for today’s world. The eighth and final generation DeVille was built from 2000 until 2005.

DeVille marque of excellence

The 2002 DeVilles are equipped with Northstar…it began as a high-performance engine and evolved into a sophisticated electronic network of art. The 32-valve DOHC engine is teamed with an anti-lock 4-wheel braking system, all-speed traction control, speed sensitive steering which adapts to the driver’s style, and a “thinking” suspension with electronic level control.

On-board computers coordinate this ingenious teamwork to result in refined driving dynamics under all driving situations to maintain optimum overall vehicle control. The DTS further refines the network to include as standard equipment, StabiliTrak 2.0 which can detect improper traction and steering issues through an array of sensors located throughout the suspension to instantaneously apply the correct calibration to the front brakes as required. The impressive Northstar system is a quantum leap forward in automotive engineering.

DTS

Northstar 32-valve V8 engine

The Northstar V8 is a series of General Motors most technologically advanced 90 degree V-type engine architecture. Cadillac Motor Division offered two types for the 2002 model year. The high-output L37 powers the exclusive DTS and the high-torque LD8 powers the base DeVille and the upscale DHS. These aluminum transverse-mounted V8 engines are the industry’s most complex powerplants. When they are good…they are very, very good…but when they are bad they are horrid! The Northstar V8 was refined for the 2000 model year with updates to improve fuel economy and lower exhaust emissions making them operate on regular grade fuel.

I own a 2002 DeVille and have driven it since 2002 burning 93 octane premium fuel exclusively. Let’s be real…if you drive a high-performance automobile; burn high-octane fuel for optimum performance especially as the engine ages. I like the thrill of dropping the accelerator pedal to GO…like, right-now! You can do this easily with smoother performance on high-octane petrol. If you can afford the car…you should be able to afford the gas – ask any Cadillac owner with the Northstar and they will tell you; high-octane fuel is the way to GO!

Technology

The L37 is the original Northstar and is tuned exclusively for high-energy output. The LD8 is the luxury cruisin’ high-torque variant. They both are naturally aspirated and share the basic Northstar logistics. The LD8 uses a different cam profile lowering the hp but boosts torque output in the lower rpm range to improve throttle response for quicker acceleration.

The 2002 Northstar V8 engines have die-cast aluminum blocks built using the “Squeeze Casting” process for the lower crankcase to reduce aluminum porosity. The downside to this design is the fact they may promote oil seeping through and leaking. (Behave) A Nylon 66 thermoplastic intake manifold keeps the intake air cooler by conducting less heat from the engine.

The cylinders have cast-in-place iron liners that are not replaceable. Some think they can rebuild these with modern aftermarket products, but my advice is to just replace them with new heads. Each head has two camshafts; one for the intake and one for the exhaust. Direct-acting hydraulic lash adjusters are positioned over each of the 32 valves. It features roller valve lifters, a low-friction valve train, and coil-fired spark plugs. This coil-on-plug design eliminates spark plug wires which increases spark efficiency.

Northstar V8 engine

Each head has its own ignition module in the center of the valve cover. This advanced design ignition system runs in two modes of operation: module mode and ignition control mode. The PCM (Powertrain Control Module) controls ignition timing via sensor inputs.

The PCM controls both engine and transmission operation. Should the PCM fail, the module mode takes over operating the engine with a fixed 10 degrees of advance allowing the engine to continue operation in what the engineers call the “limp home mode” with somewhat reduced performance to protect the engine.

The overhead cams are chain-driven with an intermediate chain sprocket under the front cover that connects to the crankshaft. This design uses three separate hydraulic tensioners to keep the chains lightweight for efficiency. Two crankshaft position sensors and a camshaft position sensor are used to provide timing input. Each crank sensor is located on the rear head in front of the exhaust cam. The Northstar V8 has a knock sensor on the rear head between cylinders one and three to reduce timing if detonation becomes an issue under load.

The beauty of the Northstar engine is the on-board computer diagnostics monitoring the electronic network. The Powertrain Control Input Module monitors the sensor inputs, battery voltage injector pulse width, engine rpm, throttle position switch, brake pedal switch, and transmission gear switches. The PCM output checks the EVAP & EGR systems, torque converter clutch solenoid, A/C compressor relay, and transaxle solenoids.

The Northstar was designed to be a relatively low-maintenance V8 engine. “Out of the box” it comes with platinum-tipped spark plugs that have a 100,000+mile life span. I purposely wanted to see how long the plugs could last. I replaced them at 125,000 miles, not because I had to…I wanted to see the plugs.

She now has 134,000+ miles and “Donnajean” still runs like a scalded cat! (I named her after the Knots Landing  vixen Donna Jean Miller aka Donna Mills)  Even before the plugs were replaced, she still ran as smooth as silk without either misfiring or rough idling. This car runs at 134,000+ miles…just as it did with only 13 miles – fantastic. With its inexorable demeanor…it’s a keeper!

The Dex-Cool antifreeze is guaranteed for 5 years/150,000 miles. The chain-driven cams eliminate timing belt replacement. Even the oil change schedule is extended to 10,000 miles. For 2002 it is extended to 12,000 mile intervals. Depending upon the use, GM states it should be changed at least once a year. The oil is the life of the engine. I am old-school when it comes to this; I believe it should be changed every 3,000 miles. After all, an oil change is cheaper than replacing a Northstar V8 engine.

Then…add the fact that there are very few engine re-builders doing Northstar restorations because these are complex machines. The heads are cast away if the valve guides are worn, the cylinder heads are simply replaced since the liners cannot be replaced nor over-bored. (why even think about trying to rebuild the heads from an engine like this?)

There isn’t much left to rebuild. Cleaning the throttle body and EGR valve is recommended. The 2000-2001 Northstars have an idiosyncratic nature to build up carbon deposits in the combustion chambers causing cold-knock conditions.

DTS 2

2002 Cadillac DTS ($43,810 – $47,880)

The DTS is the ultimate touring DeVille experience. Its power is derived from the laudable L37 4.6 litre 32-valve 279 CID V8 engine with sequential fuel injection. The engine cranks 300 hp @ 6,000 rpm with a respectable 400 Nm of peak torque @ 4,400 rpm.

The transverse mounted V8 is mated to the GM 4T80-E front-wheel drive “Smart” 4-speed automatic transmission with overdrive and electronic shift control. Longitudinal acceleration is rated as: 0-60 mph in 6.7 seconds, 0-100 mph in 17.6 seconds, and 0-120 mph in 27.1 seconds. It has a top speed in the 147 mph range (ungoverned). It can do the ¼ mile @ 93 mph in 14.9 seconds.

Both DHS and the DeVille base sedans are powered by the venerable LD8 and are geared for an elegant ride with the emphasis on torque-thrust. They are also 4.6 litre 32-valve 279 CID performance behemoths equipped with sequential fuel injection and mated to GM’s 4T80-E 4-speed automatic transmission with overdrive.

This transverse mounted V8 engine is tuned to deliver 275 hp @ 5,600 rpm packing a prolific punch with 407 Nm of peak torque @ 4,000 rpm. Longitudinal acceleration is rated as: 0-60 mph in 7.2 seconds, 0-100 mph in 18.5 seconds, and 0-110 mph in 23.8 seconds with a top speed in the 149 mph range (ungoverned). This version of the formidable Northstar can do the ¼ mile @ 94 mph in just 15.2 seconds.

The 2002 Cadillac DeVille is a contemporary masterpiece from the master craftsmen. The architecture is timeless…elegant, sporty, yet highly sophisticated. The DeVille is a wedge-shaped envelope of aerodynamic efficiency with a mere 0.3 coefficient of drag which adds to its excellent mpg average – it is the unexpected economy car. I have witnessed this first hand. I have a lead-foot and average 18-20 mpg in the city and have obtained 35+ mpg out on long stretches on the highway with speeds averaging between 75-85 mph…but this is burning 93 octane petrol.

A DeVille has always presented an understated luxury which made it America’s favorite luxury car. This genre Cadillac lacks the meretricious kitsch today’s luxury cars provide at no extra cost. The DeVille has a distinctive front end ensemble. The one-piece composite headlamps aid its aerodynamics and have a jewel-like appearance.

The aluminum hood slopes gracefully into the traditional Cadillac-style egg crate grille. There are no sharp edges or dangerous protuberances to interfere with its superb aerodynamic efficiency. The overall design is clean, tasteful, and stylish…as for its opulence, that’s for lagniappe compliments of Cadillac. The 2002 Cadillac DeVille has strikingly good looks and will challenge the years gracefully.

The rear end design is equally dramatic. The Cadillac DeVille was among the first production automobiles to offer LED tail lamps for the 2000 model year. This unique feature uses a thin light bar with a reflector to create a holographic effect reminiscent of the tail lamps from popular Cadillacs from the past. This creates a spectacular light show at night. Since LED tail lamps illuminate faster than incandescent bulbs it gives motorists behind the vehicle faster response times.

A thin LED light band across the face of the deck lid illuminates each time the brakes are applied for added visibility both day and night. The DeVille’s back-up lamps are neatly placed within the license plate housing. Dual quad chrome-plated stainless-steel exhaust tips augment the lower rear bumper diffuser and are tuned to a deep baritone for the sound of power it delivers…the stainless-steel exhaust system lasts longer than the previous versions.

The 2002 Cadillac DeVille is built by monocoque construction fusing the body shell to its platform framework. Its excellent ride quality is due in no small part to the independent 4-wheel suspension with electronic ride-height control. The front-wheel drive chassis is quite sophisticated.

It employs all-speed traction control, 4-wheel disc brakes with ABS, and standard on the DTS…StabiliTrak 2.0 for added security. The DTS is exclusively equipped with Continuously Variable Road-Sensing Suspension (CVRSS) which is a computer-controlled active suspension system with adjustable computer-controlled shock absorbers.

This genre DeVille is the last of the big-bodied Cadillacs. They ride upon a 115.3” wheelbase (which is considered long when compared with the present day make-believe Cadillacs), is 207.2” in length, 74.5” wide, with a 56.7” height. I like the size of my 2002 DeVille…this is the smallest car I will ever drive.

Here’s a chuckle…I had the hardest time finding whitewall tires for my car last year – I didn’t realize I was one of the few people who still like the look of whitewall tires on a Cadillac. The first tire store I visited, all I got was a hearty laugh from the salesman who thought I was joking…the second tire store I visited, I received a vacant stare when I asked for whitewall tires! This type of tire adds class to a Cadillac…they look like a utility vehicle without them…

The 2002 Cadillac DeVille uses a 21st century approach to cabin luxury. The DTS is the Cadillac of Cadillacs; it’s a five seat ambiance of sheer exhilaration. Two ergonomically designed individual front lounge seats coddle its passengers in elegance and share a center console. The gear shift lever is conveniently placed within the driver’s grasp.

Rich Zebrano wood accents trim the dash, gear shift knob, and door garnish inserts to make the cabin of the DTS the epitome of automotive opulence. Back-lit analog gauges are easy on the eye offering information at a glance. DTS is for the driver/enthusiast who seeks a sporting elegance. The perforated Nuance leather seating areas are unique to this model. The DTS is more dash than flash. It’s designed to compete with the Mercedes S-Klasse and the BMW 7-Series. The 2002 DTS is a luxury sedan like no other luxury saloon; it has Cadillac exclusivity, Cadillac supremacy, and Cadillac character without ambivalence.

Optional at extra cost is Cadillac’s Ultrasonic Rear Parking assist. Sensors in the rear bumper “beep”  in the cabin starting softly then full crescendo when the vehicle is in within striking range of a rear object or vehicle. There is also a light in the upper rear window trim that is green when you are good to go, and flashes red the closer the car gets to a rear object or vehicle when the transmission is in reverse gear. This is very handy since the car is designed where one cannot see anything below the rear window while driving.

DeVille DTS 2

The eighth and final generation of the Cadillac DeVille was built from 2000 until 2005. These elegant luxury sedans are equipped with transverse-mounted Northstar LD8 & L37 V8 engines with front-wheel drive. They are among the last of the big-bodied Cadillacs. The formidable Northstar began as a high-performance, high-tech V8 engine and evolved into a network of advanced automotive technology. In 2002 Cadillac had existed for a century and DeVille nomenclature is attached to some of the most dramatic automobiles for half this time span.

The Cadillac DeVille was and remains America’s favorite luxury car. The 2002 DeVilles are sophisticated and highly distinctive among 21st century luxury automobiles. From their avant-garde styling…to the powerful Northstar V8 under the hood, the 2002 DeVilles deliver the poised dignity which was the hallmark of every Cadillac. NotoriousLuxury presents this encore performance…in the continuing saga of “As the Standard of the World Turns.”

  1. Too bad they are gone, but to me, the true last Cadillac was the 1993 model year, full siza car, with some noticeable chrome appliqués. Cars with plastic bumpers, of any make, whatsoever, are no real vehicles, just a poor imitation of a long gone era. Just to cope the European invasion? Too bad that Cadillac lost its cachet as a luxury flagship and fall into a classification that no longer represents what it used to be. Even though they tried to use fake wood trim in the interior.
