The 2010 Deville Struggles for Fuel Efficiency

The 2010 Cadillac Deville is known as the DTS in most parts of the world, and like most large luxury cars the ’10 DTS is relatively heavy. Tipping the scales at approximately 4,009 pounds (depending on configuration and options), it is not surprising to see that the newest flagship luxury sedan from Cadillac struggles to garner an official EPA rating of 15 miles per gallon in the city driving and a meager 23 miles per gallon on the open highway.

While weight is certainly an issue in a car this size, the aging 4.6L North Star engine and four speed automatic transmissions are showing their age. With numerous competitors from both home and abroad offing similar power with only six cylinders and far less displacement, not to mention the use of regular unleaded fuel versus Cadillac’s reliance on premium high-octane fuel, it would seem that the weak link in this luxury sedan is under the hood. It is also worth noting that GM’s North star system is fairly heavy when compared to rivals, and the company plans on phasing the aging platform out in the near future in an attempt to remain relevant in a highly competitive market. The fuel efficiency in the 2010 Cadillac Deville is further hampered by poor aerodynamics. The new Caddy sure looks the part of the stalwart American luxury sedan, but that old-school appearance costs points when it comes to drag. Unfortunately for environmentalists who would love to drive a Cadillac, image is certainly an important aspect of the brand and thus it is probably fair to say that the aerodynamics are unlikely to change radically in the near future.

Cadillac Deville – The Innovations Are Less Impressive

Almost after three years the GM has come up with change in their Cadillac Deville. The sale ratio of this once upon a time ‘my dear car’ drowned below the expected line for various reasons. Now the new 2008/2009 Cadillac Deville Coupe has been launched after lots of innovations in the interior and to some extend the exterior looks. But the innovations no longer impress you as you explore that the vehicle is stuck with the old model engine which was there in their 2005 models as cadillac deville. The innovations of the car were on the areas of sitting arrangements of the front seat, Magnates variable assist speed-sensitive steering and the optional Stability technology which is combined with a the 4.6 L DOHC engine for outstanding control, ride and safety. The only plus points of the new 4.6-liter DOHC 32-valve V8 engine is that it delivers low emissions, excellent mileage even with regular fuel and has more smooth and quite operation than the previous engines.

The History of Deville Engines:

Cadillac Deville was once the best class leading automobile technology when it was launched in 1985. With new launches more and more technology had been added which included some sophisticated accessories. It was in 2000 when a major breakthrough occurred the manufacturer redesigned the car and also developed the engine of the vehicle. In the year 2000 they introduced the 4.6 L LD8 North star V8 engine which had 275 hp (205 kW) at 5750 rpm and 300 ft-lb (373 Name) at 4750 rpm. It was the engine for both the base and DHS trim of the car. The engine was quite powerful to compete with other makes, but due to bad fuel efficiency the car lost its market value and slowly the sales decreased. But for DTS Cadillac Deville trim GM kept the 4.6 L L37 North Star V8 engine which was available for the trim Concourse. The engine was capable of putting 300 hp (224 kW) at 6000 rpm and 295 ft-lb (400 Name) at 4400 rpm. In 2005 the same V8 engine was kept for DTS trim with slight change in horsepower and torque. IT was now letting out 290 hp (216 kW) at 5600 rpm and a torque of 285 ft-lb (386 N”m) at 4400 rpm. The present 2008 Cadillac Deville has the new 4.6-liter DOHC 32-valve V8 engine. Instead of North Star engine they are now using DOHC engine to get a better mileage than previous records. But it could not provide such a good mileage which other segment of car in this range can provide. But these changes could bring no impressive features to the car for people who want power as well as mileage.

Cadillac Deville – A Great Worth For Your Money

 Several opulent models of Cadillac’s have been using the name The Deville. Subsequent to the drop out of Fleetwood from the line up of the Cadillac, Deville has emerged as the leading Cadillac sedan. Nonetheless, in the later models Deville was substituted by Deville Touring Sedan.  Deville, the name of the car is derived from the styling of its body that has an unbolted compartment for the chauffer and the compartment for the passengers is enclosed. The parent company of Cadillac Deville is the General Motors and is this car assembled at Detroit, Michigan. The predecessor of this full size luxury car is Cadillac Series 62.

Distinct Features

New additions to Cadillac Deville series are Deville High Luxury Sedan abbreviated as DHS and Deville Touring Sedan or DTS which substituted editions of D’Elegance as well as Concourse. The various facets that were responsible in making this car a part of luxury class is GM’s On Star emergency, airbags on the front side, airbags on the rear side (optional), LED technology that comprised newly developed tail lamps which illuminate much faster in comparison to the base models.  Analogue gauges comprising in average leather upholstery as well as lumbar-massaging front accommodation was also one of the features of DTS and DHS.  Steering wheel with controls for climate as well as audio were employed which also included separate temperature adjustments for the back seats. Various facets that make this car appreciated is rear-level control system, on-star assistance, ultrasonic rear parking that offers visual as well as audio warnings, cooled as well heated seats, satellite radio, traction control, DVD Navigation and many more.


The engine capacity of Cadillac Deville is 4.6L V8. The fuel economy of this car on the highway is 26 Mpg, whereas on the roads of the city the average given by this car is 18 Mpg. The acceleration of this model is exceptionally good as it can reach 60 mph in around 7 seconds. The night vision is equipped with infra red technology which projects the view of the image on the windshield.

Comfort and luxury

Premium fuel is recommended by Cadillac. However, use of the regular fuel is also acceptable at the same time keeping in mind the performance of the car. The space for legs in the rear part of the car can be compared to that of Limousine. The cushion is firm as well as wide, which makes it ideal for three grown-up people. The entry and exit to the car is convenient as the doors of Cadilac DeVille are remarkably wide. The material for cabin is notable for its workmanship and is better in comparison to the others.

Cadillac’s 2010 DTS Frontal Impact Protection System Gets Highest Ratings

The DTS comes standard with front, side, and curtain side airbags; traction control; four-wheel antilock disc brakes; brake assist; daytime running lights; and GM’s StabiliTrak Electronic Stability Control system. Unlike many cars in this price class, the DTS does not offer seat belt pre-tensionless or other pre-collision systems. The DTS offers several novel safety options. The Side Blind Zone Alert system flashes warning lights in the side mirrors and sounds a tone if another vehicle is in the Cadillac’s blind spots. The Lane Departure Warning system triggers a dashboard light and a warning chime if the DTS leaves its lane without signaling. Both systems are standard on the Platinum model and optional on the DTS Premium; they are not available on base or Luxury models. Premium and Platinum models also include Ultrasonic Park Assist, a rear-obstacle detection system. Road tests say the DTS has acceptable emergency handling, but its panic stopping distances are longer than average for this class. The NHTSA awarded the Cadillac DTS five stars (its maximum rating) for driver protection in frontal impacts. The DTS received four-star ratings for front passenger protection, side impact protection (for both front- and rear-seat occupants), and rollover safety. The Insurance Institute for Highway Safety rates the Cadillac’s frontal impact protection Good (the highest rating), but side impact protection ranked only Acceptable; many comparably priced sedans receive Good ratings in both areas. GM classifies the standard On Star system as a safety feature, because it will automatically contact emergency personnel in the event of a crash. However, On Star requires a monthly fee after the first 12 months.

Cadillac – The Swagger Is Back

Our former Operations Manager drives a Cadillac STS. “Big deal” you say, but it’s a very big deal. Chris is a 40-something automotive connoisseur, and his past rides have typically originated from Sweden, with a long line of super sanitary restored Muscle cars. He hails from a family of RISD trained, cutting edge product design types, and again, they tend to favor the tidy offerings from Saab and Volvo. So, for Chris to risk ridicule at the Thanksgiving table for owning a Cadillac is a tantamount to an automotive sea change. But, no one in the family finds fault with Chris’ recent choice of steed. Make no mistake, we are witnessing a minor miracle in the making. A total about face in Cadillac’s corporate zeitgeist, market perception and product line – and that’s a wonderful thing Fifty years ago, Cadillac proudly proclaimed itself “Standard of the World” and that claim was not idle boast. In 1912, Cadillac won the prestigious Dewar Trophy for manufacturing excellence. At a time when most automobiles were painstakingly hand assembled with considerable custom fitment and component rework – several production Cadillac’s were completely dismantled, their parts co-mingled and the cars reassembled with no rework allowed to any of the components. These cars were then driven 500 miles each with no mechanical failures of any kind. A stunning achievement – It spoke to Cadillac’s impressive levels of production accuracy, manufacturing process control and standardization. Mind you, this achievement coming long before the era of advanced metallurgy, CNC machining and damming inspired total quality management. For 50 years hence, Cadillac was known as an engineering, quality and design leader, with innovative features such as electric starting, automatic transmissions and some of the most exuberant Harley Earl inspired styling the world has ever known. In those days, a Cadillac in the driveway signified financial wherewithal, social standing and prestige. A Cadillac was truly something special.

The party came to an abrupt end in the 1970s and 80s, as a succession of Middle East oil embargoes catalyzed a precipitous rise in fuel prices. Cadillac responded with a series of engineering fiascoes such as the V8-6-4, Diesel Seville, and the Cavalier based Cimarron. Cadillac compensated for the poor engineering with over the top baroque styling intended to evoke the past glory days. Again, they missed the mark – so that by the 1980’s the only people voluntarily driving Caddies were the white belt/white shoe Florida crowd and the, ahem, “urban adult entertainment managers” with names like Huggy Bear and Sweet Lou. We actually owned a 1982 Coupe Deville, and it was, speaking bluntly, a piece of utter vehicular excrement. Grim times indeed.

A decade later, automotive sophisticates like Chris are returning to the Cadillac marquee. In this hyper competitive global economy, very few companies get the mulligan – and Cadillac is determined to stay in the game this time. Whether or not Caddy has regained the title of “standard of the world” is debatable, but there’s no denying that the swagger is back. 13 years after it’s introduction, the world class North star DOHC 32v V8 remains fresh, potent and competitive. We recently enjoyed some extended seat time in a North star powered Deville and the car positively ate up the Midwestern miles at a refined, leisurely and feloniously illegal 125 MPH plus. The V Series of performance cars is boisterous and pretty darned exciting – all boasting a sub 5 second dash to 60. While the flagship XLR has yet to achieve sales projections, the CTS is selling briskly and the SRX and Escalade SUVs are market leaders. The “Art and Science” design motif is a polarizing, like-it-or-hate-it look, but certainly less controversial than Chris Bangle’s “flame surfacing” styling at BMW. Heck, we even get a Led Zeppelin flavored ad campaign to remind us that Candy is sincere about wooing the 40 year old market. We are serious car people – and our peer group is largely comprised of serious car people too. Cadillac has begun to get our attention, our interest and our dollars. The management team at GM has been pummeled recently by the press, but they deserve some props for the about face at Cadillac. Once again, Cadillac is an apparition brand for car lovers – a sure sign that all is right in the automotive world.
