Clean Diesels like the 2009 VW Jetta TDI are a high-mileage alternative to gasoline-electric hybrids, and the Jetta TDI is the most affordable Clean Diesel in the US. In spite of strong opposition from Greenies to their widespread sale, including strident opposition from the California Air Resources Board (CARB), Clean Diesels deliver exceptional fuel efficiency combined with excellent performance, the technology is proven and 50-state legal, there are no issues about manufacturing or eventually disposing of large battery packs, and they’re quiet, reliable and fit into existing vehicles. Diesel comprises approximately 24 percent of the first stage of the crude oil cracking process. It makes sense for 20-24 percent of the US fleet to be powered by Clean Diesels. A Clean Diesel turbo six-cylinder would provide the torque needed for a full-size American SUV, but deliver dramatically higher fuel mileage. Remember, WE DO NOT need to drive Obamamobiles.

Who’s The Buyer?
The Jetta TDI Diesel is for you if:
- You are an early adopter of advanced technologies, and understand Clean Diesel even if your neighbors don’t.
- You need a practical sedan, but rarely have passengers in the rear seat.
- Your personal image simply won’t accept the larger, roomier but more anodyne Japanese alternatives: Camry, Accord, Maxima.
The Jetta TDI isn’t for you if:
- You’re a devout Eco-pagan and will only drive a Hybrid or Tesla, even if all those batteries pose a greater long-term environmental problem than anything coming out of a Clean Diesel’s exhaust.
- You need a large rear seat for carrying adults on a regular basis, in which case go for a Camry Hybrid to combine Eco with a big back seat—Jetta’s rear seat is for children.
- You think VW is too funky and prefer the safe image of Japanese or perhaps American family sedans.
Alternatives To Consider
- Honda Civic CNG: CNG is ideal for buses, UPS trucks and other vehicles that are not commonly parked in covered garages (the gas can collect against the ceiling, according to a fire chief we know). CNG can serve in some applications, extending our useful domestic energy supplies.
- Toyota Prius: Still the greatest Eco symbol, and the new car is just that much better than the previous one. If you want a hybrid, this is the one.
- Toyota Camry Hybrid: Hybrid feel-good with a big back seat, excellent passing power. Go easy on the throttle and Camry Hybrid delivers great in-city mileage.
- Nissan Altima Hybrid: An also-ran, but worth a look.
- Fusion Hybrid: Another also-ran, the new Fusion has a dramatically better suspension, and hopefully meets current higher standards for Ford quality.
MODERN DIESELS, like the one in the 2009 VW Jetta TDI I drove a short while back, are not what you think they are. A good friend in England, who manufactures the McRae Dakar buggy, replaced his BMW M3 CSL with a current 5-series Diesel. Did he regret the move? Not at all. He frequently brags about the day a French policeman pulled him over, having clocked the 5-series at 110+ mph. My friend, flat-footing it to his place in Switzerland for a week of skiing, always says the BMW Diesel is absolutely delightful to drive at these high cruising speeds. Of course, when the policemen saw the two sons in the backseat with their English rugby shirts, he let my friend off with a warning. The French do love their rugby.
Our friends at ALMS will be disappointed if we don’t mention the supremacy of the Audi R10 and R12 Diesel-powered LMP1 cars, which have swept the boards at Le Mans—and the basic bits and pieces of the Audi Diesel racing engine are production-derived.
VW wants to push Clean Diesel into the American mainstream. With our desire to be “energy independent,” Diesels seem an obvious component in a cohesive national strategy, if ever we develop one.
Engine, Transmission, Drivetrain
Diesel technology has matured, and the German manufacturers want to convince Americans it’s the way ahead, rather than hybrids and electric cars. They’ll have a stiff fight against the Eco-pagans that infest the Obama administration, even if the Germans are at least partially right.
To cut to the chase, the story here is a Clean Diesel four-cylinder engine paired with a dual-clutch 6-speed transmission, a combination that delivers phenomenal fuel mileage: 29 in the city, and 40 on the highway. Compare that with an Accord four-cylinder: 21/24 mpg. Or if you feel generous, with a 140 hp Civic sedan: 25/29 mpg. Perhaps even with a Honda Fit: 28/31. Admittedly, the Jetta TDI costs about the same as a nicely turned out Accord four-cylinder, but leave off a few options and the TDI is under $25K.
Let that sink in. The Jetta is bigger than a Civic, yet compared to the Lilliputian Honda Fit, Jetta TDI racks up another nine miles for every gallon on the highway. Hmmmm. The only downside is that low-sulfur Diesel fuel costs about the same as Premium gas, and fueling can still be a nasty experience in the US, as Diesel dribbling on the gas station’s forecourt can leave quite a slippery mess.
The combination of all that torque and the optional DSG dual-clutch transmission is truly impressive, and makes for an engaging family car, ideal for commuting and long-distance trips. The torque wells up at 1,750 rpm, really moving the car along, and shifts are as precise as anything you’d get in an F1 Ferrari. The first time the car clicks off 2-3 and 3-4 shifts under heavy throttle, you’ll be stunned by the immediacy and precision of the shifts. Ford, among others, is exploring the use of these dual-clutch gearboxes in their entire product range, as their tremendous efficiency more than makes up for the added expense of two clutches and what amounts to 1.5 gearboxes worth of machined steel bits. To better understand the advantage of these gearboxes, bear in mind that with the addition of direct injection and Porsche PDK dual-clutch transmission, the ’09 Boxster S and Cayman S get better than 30 mpg on the highway—yet they both have more than 300 hp. The gearbox is a big part of that, as dual-clutch boxes are highly efficient. When driving the Jetta TDI, use the standard cruise control on the highway to ensure even throttle application and the Jetta TDI delivers as advertised: 40 mpg.
Once you get into the rhythm of Clean Diesel power, the Jetta becomes a wonderful road car—so long as you’re in the roomy, orthopedic front seats. Thanks to the torque, the Jetta TDI can simply blast by slower cars—no effort, no sweat, your overtaking pass has been executed. My thought after only a short drive in the car? Why not apply this engine technology to large American SUVs, with a turbo six-cylinder Diesel? You’d have ample torque, enough to rival a gasoline V8, and double the highway mileage of a gas-powered Tahoe or Expedition. A Diesel Touareg might answer the question. Then again, such product planning can only take place if we have sane energy policies coming out of DC, and we won’t see that anytime soon.
The VW Jetta TDI engine is surprisingly quiet and smooth—killing any lingering images of smoke-belching, rattling Mercedes and GM Diesels from the Seventies and Eighties. Yes, the VW TDI’s popcorn machine sound at idle lets you know this is not a gasoline four-cylinder, but the VW TDI motor impresses on all levels. This combination of Clean Diesel and dual-clutch transmission is truly a way forward.
Jetta TDI also has standard stability control (which means standard ABS, electronic brake-force distribution, and traction control, of course), key safety features one should always expect on a family sedan.
Interior, Ergonomics
Interior materials are fairly high quality with a soft touch, though I’d choose one of the darker interior colors to help mask seams and show off the limited bright trim. My test car had the tan dash and leather, and I found it less than successful because the color brought unwanted attention to the many seams and joints on the dash.

Details are well-finished, from the chunky steering wheel to the integration of the navigation unit into the center stack. The Jetta TDI has a clean, efficient, and tightly finished driving environment.
Driving position is typically German: you place the man in the proper upright driving position, then design the car around him. I’m six three and was comfortable behind the wheel. The steplessly adjustable tilt and telescope steering column—which feels a bit like the helm of a U-boat when you’re adjusting it—combined with an 8-way adjustable seat ensures virtually anyone will find a comfortable driving position. As a friend said recently, only a German car feels like a German car—and the Jetta has all those wonderful traits. As one expects from Germans, so obsessed with posture and orthopedic shoes, the chairs are well constructed and supportive.
Gauges are clean dials: black face, red markers, blue lighting. Gone is the effective if perhaps too affected iris and red gauge lighting of the Nineties. I admit that when VW first introduced the iris-and-red gauges, I thought they were a wild signature item, and they certainly worked well at night. But the iris element was a bit too West Hollywood fashion forward and grew tedious over time. I’m glad they’ve returned to a more classically inspired design.
Where does the Jetta fall down? The rear seats are adequate for adults on cross-town drives, but no taller-than-average male will ever accept a long stint in the back seat. Compared to Camry, Accord, and the new Mazda6 (a very pretty Camry clone in many respects), the Jetta rear seat simply doesn’t have generous leg, foot and head room. The Japanese decision to engineer bodies specifically for the US market pays off in a bigger back seat and corresponding bigger sales; the Jetta has dimensions better suited to Europe. If you’re single, the Jetta is a perfect four-door. If you have a starter-kit family with a baby or two still in safety chairs, the Jetta will deliver. But if your kids are teenagers, forget it, unless you’re a family of circus midgets.
One point of note: with the available navi system, the audio controls include a digital representation of an old-fashioned radio along the bottom of the LCD screen. You spin the right knob to change stations, and a red line scrolls across the radio spectrum for you, as if you’re in a 1968 VW Beetle. A clever approach, and a bit of German humor, giving a comforting analog representation to a digital device. The 10-speaker audio system delivers crisp reproduction, and the CD player reads MP3 files. VW should look to addition of a USB port to connect and charge iPhones and iPods while also ensuring sharper transmission of digital audio files—and WMA and AAC are increasingly popular formats. Currently there’s only an AUX port. The steering wheel includes audio controls.
Jetta TDI is the top of the Jetta range, so it comes with remarkably high feature content, including leather seating and shifter, the previously mentioned chunky leather-wrapped steering wheel, and a sunroof. Jetta TDI is a very nice place to spend time.
Exterior Design, Body Construction
Unlike the Bangle and Von Hooydonk BMWs, and some of the Mercedes that are simply overwrought with their bulging fender lips and gargoyle faces, VW has remained true to Bauhaus. VW has NOT given in to fashion and stands apart for it. Jetta has timeless, clean proportions that will age well. Body panels are well formed with fairly tight panel gaps, though this is one area where Honda and Toyota are the unrivaled masters and VW must raise its game. Still, the average person won’t notice the difference.
Because every wooded copse in Germany seemingly hides a family-run wheel manufacturing plant, German cars typically offer a wide range of cast or forged wheels, and the Jetta is no different. The price is a bargain: $450. Factory alloy wheels often will cost twice that. So my recommendation is to indulge yourself with the 17’s if you drive mostly on well-maintained roads where the bigger wheel won’t impact ride quality.
Steering, Suspension, Brakes
For a vehicle with a multi-link rear suspension, the Jetta has a surprisingly harsh ride over many road surfaces. On fresh asphalt, fine. But over the types of roughly maintained highway one finds in Southern California where I drove the car, the rear suspension can kick up a racket. I found this disappointing.
Also, the Jetta shares the same failing as its GTI cousin: the rear suspension has what one might call a kinematic hiccup—or at least that’s what a suspension engineer we know calls it. When pressed in a corner, the rear suspension has a kink in its action. But, to keep this car in context, it’s the rare owner who will ever push the Jetta TDI that far. We still think VW ought to iron out the problem. Our recommendation would be a rethink of the damping and bushing, and perhaps application of foam inserts to deaden the sound drumming in the trunk and into the rear seats. As to the source of the “hiccup,” we’ll leave that to Germans in lab coats.
Dynamics are acceptable if not inspiring. My normal road test includes a run up and down one of the best canyons in Southern California, another on a low-speed and very tight canyon road, and various freeway on- and off-ramps. Jetta’s electro-mechanical steering is far too quick when coming off center and one must mentally adjust to avoid several corrections throughout a sweeping corner. Also, one must accept it’s a family sedan and not a sports car, so you can’t simply throw it into turns. The steering has little feel and gives very little information. VW can do better. Again, to keep things in context, my daily driver is a premier sports car, so every car feels uncoordinated on my first drive.
EXCEPTING a few flaws, the VW Jetta TDI is well-suited to a single person or starter-kit family; it’s an exceptionally good sedan. The fuel mileage is astounding, as placed in perspective above. Why would you want a Honda Fit or Civic when you could get a Jetta TDI with its vastly superior mileage, more soulful character, and greater room? The dual-clutch transmission remains a modern marvel, and a big reason for the excellent fuel mileage. Plus, the transmission is so quick and precise, it’s a joy to use. Order the interior in a dark color, don’t shove tall people into the rear seat, and you’re going to love it.

I had a very similar Jetta TDI for testing, and went 280 miles on half a tank. Who would want a hybrid with all of its battery concerns (life, creation, disposal, cost, etc) when you can get this kind of mileage without any compromise? There’s nothing like cruising around town getting +35 mpg, and roaming the highway at +45 mpg. (I’m being a tad conservative here. At times I was seeing consistent numbers that were much higher.) Plus, it scoots when you make an urgent call to the engine room. I was very, very impressed.
My car had the full navigation system, and that means it had an iPod connector under the center armrest. It also had a 115-volt outlet in the back of the armrest to power laptop, phones, circular saws, blenders, and whatever else you might want to plug in. Unlike you, oh muscular and tall one, I was able to sit my 6-foot frame comfortably in the back seat as long as the seat ahead wasn’t all the way back. And, with my short (30-in) inseam, that meant I could sit behind myself, so to speak, easily.
To keep the price down from the $28,038 of my test car, I’d delete the $1,000 power sunroof and the $329 rear lip spoiler. That is one expensive Gurney flap rear spoiler, if you ask me… But, though I prefer manual transmissions, the dual clutch automatic gearbox is as wonderful as ever. It snaps off shifts quickly with little jerk or judder, and is part and parcel of the car’s exemplary fuel economy. I can see why people queue up to buy them, and VW dealers offer owners of nicely kept examples high numbers to buy them back so that can sell them to those who can’t wait.
