Powertrain Downsizing In Action: Saab's Next 9-5

By Kevin Miller

08.14.2008



Replacement For Ancient 9-5 is Expected to Debut in March

Channel4.com has reported that the entry-level engine for the long-awaited next-generation Saab 9-5 will be a turbocharged 1.6 liter four. The 1.6 liter engine is in keeping with Saab's philosophy of downsizing engines while utilizing their extensive turbocharging expertise.

The smaller base engine will have more car to move around, as the new 9-5 will be somewhat larger than the current car. The current 9-5 is powered in the US only by a 260 HP 2.3 liter four which is the latest derivation of a historic Saab powertrain. Other powertrains forecast for the new 9-5 include the 260 HP, 2.8 liter V6 from the Cadillac CTS, a 2 liter CDTi diesel, and Saab's turbocharged 2 liter, ethanol-compatible Biopower engine.

Saab's recently-introduced XWD all-wheel drive system will be offered on the new 9-5, and a raised-suspension "softroader" wagon in the same vein as the 9-3 SportCombi-based crossover expected to debut this October in Paris, will join the 9-5 sedan and SportCombi wagon.

As we reported last month, the 9-5 is expected to be introduced at the Geneva Auto Show next March. It will be built in GM's Rüsselsheim, Germany, plant alongside its platform-mate Opel Insignia, with deliveries beginning next Autumn.

Integrated Booster Seats

Conveniently Helping OCD Parents De-Clutter the Back Seat

By Kevin Miller

08.12.2008




Becoming a father just over three years ago was absolutely a life-changing event. The unexpected benefits are intangible; the euphoria I experience when my daughter giggles, the way my heart melts when she gives me a kiss, the entertainment value when she sings songs from Mary Poppins while getting only about 40 percent of the words correct. Some parts of fatherhood are less rewarding: the lack of sleep, extra worry and expenditures, and having a big, bulky car seat filling up my otherwise-beautiful back seat.

For me, the car seat has been one of the most inconvenient aspects of fatherhood. As a self-proclaimed "car guy", I hate the way the car seat looks in the car. Although I drive a Volvo wagon, known as a family car, the the Graco ComfortSport car seat my daughter started using at around 6 months of age was so large that when rear-facing, it made the front seat of the car essentially un-usable, and even then it left marks in the leather of the front seatback from rubbing.

About 6 months later, I was able to turn the car seat around, and it has been that way for the past two years. I've used it in each of the three backseat seating positions, with a protector under it to protect the leather upholstery. But now, finally, I am free.

Four years ago, before my wife and I were even expecting our daughter, we custom-ordered our V70. And one of the features we intentionally chose was Volvo's integrated booster seats. Offered in XC70, XC90, and V70 models, the integrated booster in my 2004 vehicle is rated for children between 33 and 80 pounds, sized between 38 and 54 inches in height (newer V70 and XC70 models have two-stage integrated booster to expand the range to larger and smaller children). Having friends whose cars were junked up with car seats, and knowing that we tend to keep cars for a while, I was planning ahead for my own sanity by ordering the integrated booster seats.

Volvo V70 and XC70 models have two integrated boosters, in outboard rear seating positions (XC90s have a single integrated booster in the center seating position of the second-row seat). Using the integrated booster is incredibly simple. There is a latch on the front edge of each booster seat cushion. Lifting up on that latch releases the booster, which can be lifted up and pushed rearward, latching the seat in place. That raises the seating position so that the vehicle seat belt is properly positioned for a child to use it.

On a recent visit to her doctor, our daughter measured up to the minimum height and weight to use the integrated booster. Fortuitous, as the car seat usually in my Volvo was installed in the Mitsubishi Lancer Evolution GSR I was reviewing that week, and I needed to take my daughter on a run to the local home improvement warehouse to pick up some plants and soil. I popped up the booster seat, strapped in my daughter with the vehicle's seat belt (she was thrilled to be riding like a grown up), and headed off to the store.

The down side to the integrated booster is that it lacks side bolsters of any kind. The first time I went around a corner my daughter tipped over sideways (and subsequently started laughing hysterically), as she is accustomed to being held in place by the bolsters of her car seat. On a 90 minute trip during nap time a few weeks later, she was unable to find a comfortable sleeping position, so we arrived at our destination with a crabby, tired little girl. Volvo does offer a "custom upholstery and head support" accessory which covers the car's leather upholstery on the booster with a washable fabric upholstery, and it includes head support "bolsters" to facilitate napping in the car. I'm seriously considering this accessory, as it will make the integrated booster much more comfortable for my daughter to use.



Chrysler previously offered integrated child seats (with five-point harnesses) in their minivans beginning in 1992, and Saab has offered integrated booster seats in 900, 9-3, and 9-5 models in the US market. Volkswagen has offered integrated boosters (which included head bolsters) in some European Passat models. It is a great idea, allowing parents and kid-carpools flexibility in seating without hauling and stowing separate booster seats, and allowing OCD parents like myself to de-clutter the back seat.

Alas, my days of a tidy back seat will be short-lived. I am thrilled to say that my daughter will become a big sister this year around Thanksgiving. Then I'll be back to having a bulky car seat cluttering my back seat. But I don't mind... at least not much.

Ford's Blind Spot Mirror

As Close As We Can Get To European Aspheric Mirrors

By Kevin Miller

08.08.2008




Ford issued a press release this week touting their industry-first Blind Spot Mirror which is being introduced on the 2009 Edge. The Blind Spot Mirror is a traditional side view mirror designed with a secondary convex spotter in the top outer corner, which provides a view of the driver's blind spot. When traffic enters the driver's blind spot on either side of the vehicle, it is visible in the secondary convex mirror, alerting the driver of potential danger. It's a great idea, and a great improvement over traditional driver-side vehicle mirrors.

Ford's claim of being industry-first is likely true, as this mirror has the convex spotter mirror integrated only into the corner of the mirror glass, and it is the first vehicle in the US to offer such a feature. However, the idea of a rear-view mirror with better visibility is not a new one. I first encountered wide-angle rear-view mirrors in 1998 while renting an Opel Omega in Germany. The Omega had convex mirrors with curved glass along the outside edge of each side view mirror, greatly reducing blind spots around the car.

That same year, Saab introduced such mirrors to the US as standard equipment for the passenger-side mirrors of their 9-3 and 9-5 models. The Saab wide-angle, or aspheric, mirror combines a constant-radius curved area (similar to the conventional convex mirror that is common on passenger side exterior mirrors in the US), with a portion on the outside of the mirror which has a gradually increasing curvature. It is the high curvature in the aspheric area that yields a greatly expanded field of view.


This Saab press photo shows the difference between fields of view of a traditional convex mirror (top) and an aspheric mirror.

Knowing from my Opel rental experience that such a mirror was available for the driver's side as well in European markets, I used the then-new Internet and ordered aspheric mirror glass for the driver and passenger sides of my 1995 Saab 900. The improvement in visibility over the stock US mirrors was a revelation. I have done the same for both our Saab 9-5 and our Volvo V70, ordering the replacement mirror glass from European parts suppliers because it is unavailable in the US.

Knowing that mirror specifications (as well as specifications for most other functional automobile parts) are mandated by Federal Motor Vehicle Safety Standards, I did a little bit of research. I found that clause S5.2.1 of FMVSS 111 requires that the driver side of each passenger car shall have an outside mirror of unit magnification. Unit magnification is defined in FMVSS 111 as "a plane or flat mirror with a reflective surface through which the angular height and width of the image of an object is equal to the angular height and width of the object when viewed directly at the same distance ." Basically, this Federal requirement prohibits convex or aspheric mirrors from being installed on the driver side of a passenger car sold in the US. That's too bad, because it seems to go against the standard's defined purpose, which is "to reduce the number of deaths and injuries that occur when the driver of a motor vehicle does not have a clear and reasonably unobstructed view to the rear."

Ford has cleverly found a way around this requirement with the new Blind Spot Mirror, by integrating a second mirror in the corner of the standard, federally-mandated one, all within a continuous glass surface. Presumably, if the mirror glass is heated the convex portion will also be heated, which is never the case with adhesive aftermarket spotter mirrors. Though inferior in function (and field of vision) to the aspheric exterior mirrors available on both sides of vehicles in Europe, it is a great leap forward for drivers in the US who until now have had to put up with flat-glass driver-side mirrors, or add clumsy secondary spotter mirrors.

Ford's press release, which states the Blind Spot Mirror will be standard equipment on 2009 Edge crossovers, also states that the company intends to offer these mirrors on several upcoming Ford, Lincoln, and Mercury vehicles. That is great news, because better mirrors equate to better visibility, which all of us could use. And until FMVSS 111 is revised to allow aspheric mirrors in the US, Ford's Blind Spot Mirror is the best mirror available.

Tax Incentive Makes Volkswagen Jetta TDI Even Sweeter

By Kevin Miller

08.06.2008


US fans of diesel vehicles have eagerly awaited the introduction of the 2009 Voklswagen Jetta TDI sedan and SportWagen. The vehicles' shared powertrain features clean diesel technology which is compliant with emission regulations in all 50 states. The vehicles come to market over a year after the last diesel powered Jetta was available in the United States.

Last week, Volkswagen announced that buyers of 2009 Jetta TDIs will be eligible for a $1300 Federal Income Tax Credit. The Internal Revenue Service issued a certification letter affirming that the vehicles qualify for the Advanced Lean Burn Technology Motor Vehicle income tax credit. That credit was previously available only to buyers of hybrid vehicles.

The Jetta TDI employs a 2.0 liter four-cylinder turbodiesel which produces 140 HP and 236 ft-lbs of torque. It earned an EPA fuel economy rating of 29 MPG city/40 MPG highway, though Volkswagen had an independent third party conduct "real-world" fuel economy testing and touts those results to be 38/44 city/highway. Of course, your results will vary.

The Jetta TDI sedan starts at 21,990, and the TDI SportWagen starts at $23,590. The $1300 tax credit will help offset the higher price of the diesel model compared with gasoline-powered Jettas, as the tax credit equals almost 6 percent of the base Jetta sedan's MSRP. Combined with the improved fuel economy compared to gasoline Jettas (even accounting for the price difference between gasoline and diesel), the tax credit helps make the Jetta TDI a sweet deal indeed.
