What do the Ferrari 599 HY-KERS, Lotus Evora 414E and Porsche 918 Spyder have in common? They're all fuel efficient sports cars with technology that's finally fitted to something worth driving. Also, we can't buy them... yet. What's worse, when they do go on sale, mere mortals who don't log on to an off-shore account to check their net worth won't be able to partake.

So how can a gearhead tread a little lighter and still get their kicks? Read our full story to find out.

It's about a six-hour drive from the East Bay of San Francisco to AB contributor Michael Harley's place in Newbury Park near Los Angeles, and after living with our long-term Jetta TDI for the last three months, I'm convinced few attainable vehicles are better suited to the task. Yes, it might not be the most plush way to consume U.S. 101 at 80 mph – a top-shelf Merc SL would surely do the deed with more luxury and speed – but the Street Cup Edition eats up the miles with surprising aplomb, the lazy diesel finally cracking the 40-mpg mark about 20 miles outside Paso Robles (the EPA officially pegs the Jetta TDI at 30 city/42 hwy/34 combined).

Four hours in and the TDI proves its worth as an exceptional cruiser. The plaid buckets haven't numbed my rear, hands-free calls are a few clicks away and Germany's ability to insulate without isolating keeps wind and road noise just outside the cabin. Even the 18-inch wheels, slightly stiffer springs and marginally larger anti-roll bars – all pulled from the last Jetta GLI – haven't compromised the TDI's composure over some of the rougher sections of road. In nearly every environment, the TDI simply sings, albeit with a muffled staccato racket when ticking over at 1,500 rpm.

After arriving at Harley's, we give the Jetta a thorough bathing (he's got detailing toys I've only dreamed of) and head out to meet photog Drew Phillips at our shoot location. This will be the first time anyone else on staff has had a crack at our long-termer and I'm looking forward to his first impressions.

"These seats are great. Are they the same as the GTI's?" Harley asks swinging open the door. Unfortunately not. While suitably bolstered and coated in the same red, gray and black pattern, the TDI's front chairs are less sporty than those in Volkswagen's hottest hatch. Stuck in the back, Harley's son, who's spent the last few days in the Infiniti M set to serve as our camera car, prefers the VW's thrones over the luxed-up Nissan. Automakers take note: Apparently plaid is a hit with tweens.

Kiddies safely delivered to grandpa's, an hour later we arrive at our super secret shoot location and meet Drew, newbie Jeff Glucker and the Honda CR-Z. Having driven Honda's attempt at a green sports car for the past few days, Drew comes off as unimpressed. Then again, he's a GTI driver with Mustang ambitions, so the CR-Z obviously isn't his cup of tea. And when I catch sight of the gray wedge parked along our ticket-me-red Jetta, there's a tinge of worry. Maybe this was a bad idea...

Even before we decided on this undertaking, we fully recognized these are two completely different riffs on the notion of green performance. But each car's purpose is still the same. One is a three-door, two-seat hatch with a peaky engine, a hybrid drivetrain and a six-speed manual. The other a compact sedan with four doors, five seats and a trunk, along with a bone-stock diesel, dual-clutch transmission and a slightly tweaked suspension. The discrepancies are obvious, but so is the question: What's the more entertaining steer for a green-minded individual?

Within minutes of our arrival, an impromptu drag race breaks out; Drew in the CR-Z and Harley in the TDI. While we've seen independent 0-60 times for both vehicles – each generally hovering around the nine-second mark – within the first 100 feet the TDI has it. Considering there's barely 250 horsepower between our two competitors, it's the TDI's diesel torque – 236 pound-feet compared to the CR-Z's hybrid-assisted 128 – that rewards off the line acceleration. After another couple of tries, we regroup, Harley mentioning that the CR-Z's six-speed manual lets it "launch smartly off the line, but the Jetta's torque easily carries it past once speeds increase." Having driven the CR-Z before, I know what he's on about, but we both admit this isn't the kind of testing we're particularly interested in. "Obviously, neither of the two would be ideal drag racers," he clarifies, "but the Jetta wins on grunt alone."

Drew starts shuffling cars around, changing lenses, repositioning tripods and trying to catch the quickly diminishing light, and soon after we pack up and I head to the hotel. Having spent more than enough time in the Jetta, I snag the keys to the CR-Z and hit the highway, though I won't be on it long enough to see if Honda's hybrid matches its official EPA ratings of 31 mpg city, 37 highway and 34 combined. The fact that these two disparate fuel sippers share an official combined rating of 34 mpg, however, lends a little more legitimacy to our choice of rivals.

What a difference a wheelbase makes. Well, that and an autobahn-tuned interior.

It's not that the CR-Z feels rattly – just slightly unrefined when compared to the Jetta. The materials are a grade or two below what's on offer from Volkswagen, the switchgear doesn't have the same reassuring tactility and the seats are comparatively flat, with thin padding and insufficient bolstering. Aside from the disco dashboard, the two shining lights inside this Honda remain its slick-shifting six-speed manual and the small-diameter steering wheel. As per usual, Honda's shifter can shame machinery costing four times as much, with short throws, defined feedback and the slightest hint of notchiness. It doesn't beat the DSG's ease-of-use in the Jetta, but with a shifter this smooth, I'd be more than happy exercising my left leg on the 405. But at prolonged speeds above 50 mph the CR-Z is buzzy – not entirely unlike its CR-X forebearer – so depending on your proclivities, you'll either consider it a curse or character.

Before heading to bed, I spec up both testers online and it becomes painfully obvious the Jetta's uprated materials, auto 'box, extra doors and seats come at a cost. The base price of the Jetta TDI Street Cup Edition is an entirely reasonable $24,990, but tack on the body kit, DSG and a few other options and our as-tested prices rings up over $31,000. And that's without navigation. On the other end of the spectrum lies the full-kitted CR-Z EX – sat-nav and all – that stickers for $23,310. That's a serious discrepancy, but again, this is hardly an apples-to-apples comparison, and the Jetta's utility alone justifies at least part of its bolstered price tag. Besides, the Honda's aging navigation system didn't let me enter a house number, so...

The next morning, Harley and I rendezvous at the bottom of one of his favorite canyon roads for the real test: Back-to-back-to-back-to-back runs in both cars with ten-minute breaks on either side of the hill. Having arrived in the CR-Z, I take it out first and watch Harley and the TDI disappear into the distance. He knows the road. I don't. But by the time we hit the halfway point, I've got a clear sense of how fast and how hard the CR-Z can be pushed. Here, the elements that make the CR-Z a slightly uncomfortable cruiser become assets. The short wheelbase suits the road perfectly, pivoting around my hips as I turn from lock to lock, the CR-Z's steering easily beating out the Jetta in the communication department.

The road evolves from an endless series of tight, low-speed bends into a wider, longer and more velocity-friendly section, and several minutes later, I'm stopped a few hundred yards from the ocean. Harley's parked perpendicular to the road when I notice smoke billowing from the CR-Z's five-spoke wheels that are wrapped in P195/55R16 Dunlop SP Sport 7000 all-season tires. The brake pads may have been toasted, but there was barely a hint of fade.

Harley comes over to inspect the damage (none to speak of) and I (knowingly) ask how the Jetta's 225/40R18 Pirelli P-Zero Neros are holding up. He looks up and shakes his head. "The all-seasons were cooked five minutes in," he admits, "after that, it was just a sloppy mess." The mud and snow rated meats are the single reason we haven't taken the TDI to the track yet, and for this test, we wanted to keep things showroom stock. Unfortunately for the Jetta, that means it's hobbled out of the gate.

We give the cars a few minutes to cool down while we exchange notes and hop back in. Again, me in the CR-Z and Harley in the VW. This time, I keep up, and when we reach the more technical low speed section, I've already disabled the traction control after the electro-underwear cuts the (meager) power one too many times.

With a better feel for the road and car, I begin braking later, holding the middle pedal into the turn and letting the weight of the rear-mounted battery pack act as a pendulum, swinging the torsion beam rear end out and tucking the front tires in towards the apex. When I finally – and admittedly, rather quickly – reach the limits of the 195/55 R16 tires, the e-brake handle starts playing a role for quick rotations in hairpins. It's fun, if not fast, and when we arrive back at our starting point, I've got a politician's grin stretched across my face.

2011 Honda CR-Z and 2010 Volkswagen Jetta TDI Street Cup Edition

Harley hops out of the Jetta and I can tell he's enjoying himself, even if he's a little flustered. "Those additional 500 pounds are making the brakes work hard, and with the tires overheated, I was into the ABS in nearly every corner." I ask if he's bottomed out at all and he confirms hitting the bump stops over one sudden dip. The Honda never had an issue, but it's not nearly as softly sprung as the Jetta. It's not harsh, it just isn't as yielding.

Back into the Jetta and one thing becomes instantly apparent. While the CR-Z was developed from the onset as a compact runabout with sporting pretensions, the Volkswagen is, for all intents and purposes, just a tarted-up diesel Jetta. The immediate difference in size and feedback manifests itself with a slight disconnect and hesitation, but once I get back into the rhythm of the road, the size bleeds away and the Jetta's point-to-point abilities begin to shine through. The suspension breathes with the road across the faster, sweeping bends, and while not as viscerally rewarding as the CR-Z's manual 'box, the DSG's ability to drop down two gears with a couple of quick pulls makes the experience less intense and just as much fun. That rather relaxed sensation lasts right up to the point where things get truly twisty.

The brakes are already getting mildly mushy and those high treadwear tires just aren't up to the high-temp task of scrubbing speed then being thrown into a bend. Understeer comes on hard and fast, requiring nearly every turn to be a slow in, slow out affair. Whereas the CR-Z never went into severe plow mode, just pushing outward into a wide drift, the Jetta relentlessly skidded to the outside despite exercising my left foot on the brakes. As soon as the terrain began to unwind, all the Jetta's strong points came back, but by the time we make our final pass, it's obvious which car is the better backroad play toy.

"You work a lot harder in this," Harley says exiting the Honda, "but it's fun and the six-speed is a dream out here." Harley's complaints about the Jetta's DSG mirror my own, namely the automatic upshift at 4,500 rpm. "Dual-clutch gearboxes rock when you have tons of power behind them, but with the TDI, I kept trying to downshift in search of torque that was never there."

2011 Honda CR-Z and 2010 Volkswagen Jetta TDI Street Cup Edition2011 Honda CR-Z and 2010 Volkswagen Jetta TDI Street Cup Edition

I ask Harley about my favorite feature of the Honda – the battery pack and its affect on handling – and he admits it was startling at first, but "the weight transfer was easy to control with some steering input and throttle once you got used to it. It almost..." he pauses, "it almost has a mid-engine feel." I suggest he's been drinking, but I get his point.

When asked which car we'd take out for one last run, both Harley and I point to the Honda. It's simply the better driver's car here, and considering what each vehicle was developed for, that's no surprise. On these roads, the Honda has the home field advantage. But when asked which of the two we'd pick as a daily driver, neither of us hesitated: We'd take the Jetta every time.

2011 Honda CR-Z and 2010 Volkswagen Jetta TDI Street Cup Edition rear driving view

"You really can't beat the Jetta when it comes to practicality," says Harley, "and the TDI engine boosts fuel economy to hybrid-rivaling levels. Add in the Cup package and its like a diesel GTI." I can't disagree, and when faced with the mindless six-hour drive ahead of me, I'm thankful I'll be piloting the Jetta. It might not be the driver's car of the duo, but on balance, it's hard to deny the TDI's blend of functionality, frugality and fun. And given better tires and uprated brakes, there's a good chance the Jetta could have hung with the Honda all morning. Maybe it's time to call the Tire Rack...

      Its not that the CRZ is horrible, its just that it could have been amazing.
      • 4 Years Ago
      The Jetta TDI is a better buy in terms of performance, economy and interior. I just don't like the bodykit, seems a little weird. Overall, it's a good vehicle.

        Good thing that's optional.

        I guess that means you're a closeted woman, then? Because actual men, and not these "REAL MEN" drive a car because they enjoy it, not because of what your bros at the bar are going to say about it.

      Yet another test conspicuously absent of fuel economy figures.
      I know we've been treated to the figures for the long-term Jetta many times before, but how about giving us some figures from your little canyon cruise and comparing them to the CR-Z?

      After all, neither of these cars is designed expressly with that sort of driving in mind. Their main reason for existence is better fuel economy with a dash of sport. So, while the figures will admittedly not be great for that part of the test, why not share them? It's at least an interesting bit of data to mull over.
        • 4 Years Ago
        That's pretty much my understanding as well. It seems that the torque of the diesels(even over a shorter power band) makes a big difference.

        Thanks for the first hand experience.
        • 4 Years Ago
        I know that the figures aren't going to be good. I'm more interested in comparing the two different directions that these cars go towards achieving higher fuel economy.

        It's been shown in other tests that diesels, even when pushed hard, tend to offer higher economy than a gas counterpart. I wonder if that proved true here. I was also wondering how the regen braking affected the CR-Z's economy since it was a pretty spirited drive and the hard braking would seem to help the CR-Z's economy.

        Would be an interesting metric to track if nothing else. I do understand that it's not all that easy to do though.
        • 4 Years Ago
        The regernative braking didn't seem very effective when the CR-Z was flogged. It was a losing battle, as we sucked more energy from the batteries than the braking could restore. My money says the TDI did better when pushed really, really hard. It was lighter, and it had more torque down low (so it wasn't working as "hard" as the hybrid).

        - Mike
        • 4 Years Ago
        Measuring fuel economy is difficult on a short (less than 200-mile) trip — especially with two different drivers behind the wheel on a twisty, mountain road.

        We were both hard on the throttle in both cars (and just as hard on the brakes). A glance at the on-board computers for both cars indicated each were delivering less than 20 mpg during the spirited canyon drives. I don't have exact numbers, but they weren't pretty.

        Keep in mind this comparison wasn't about fuel economy. We wanted to see which was the better sports car.

        - Mike
        • 4 Years Ago
        In our test of the CR-Z versus the Golf TDI we evaluated economy. The result was the Hybrid winning on the hypermiling test, with the TDI holding better mpg when we drove "normally" (ie: not slow.)

      "hardly an apples-to-apples comparison"

      I love comparo's that have nothing in common.
      • 4 Years Ago
      Why not throw an actual Fit in the mix. I picked up a Fit Sport AT and get 36-38mpg all the time, it's a hatchback, seats 5, or endless amounts of crap, and has paddleshift, or the stick works great too. So it is super usable like a lil SUV, and it carves canyons, with no batteries (other than 1 for ECU).
      • 4 Years Ago
      "BTW, even the lastest and greatest diesel engines such as Bluetec emit something in the range of 100X heavy particulate than comparable gas engines (while admittedly producing significantly less CO2). "

      Wrong. All new US-spec diesels sold today have particulate filters and emit hardly any particulates. The exhaust pipe of my 2009 TDI is cleaner than any gasoline car I have ever owned.
        • 4 Years Ago
        Not for DI engines.

        Not surprising though. Gas engines are utilizing DI as a way to close the efficiency gap with diesels(since diesels have been using DI for a while now).

        Color me unsurprised that one of the side effects of DI(particulate matter) is also affecting gas engines that utilize DI as well.

        Considering how many more gas engines there are around than diesel, I think that's a more troubling issue(especially with the increase of DI engines each year). Particularly since you admit that diesel PM emissions are falling.

        In other words, the gap is closing from both sides.
        • 4 Years Ago
        The ALLOWED PM levels for gas and Diesel are the same. The actual levels are not the same. The PM for a regular gas engine is so low it isn't even usually measured, whereas Diesel engines currently are near the top of their allowed range (and falling).
        • 4 Years Ago
        They simultaneously emit hardly any particulates and still emit far more particulates than gas engines. 100X wouldn't be at all a surprise.
        • 4 Years Ago
        DI gas emissions are falling too. Just because PM on DI is a lot higher than regular gas right now doesn't mean it won't come down, probably using the same technology that has brought Diesel down.

        PM is really not a side effect of DI, at least not in the case of Diesel. Diesels put out far more PM before DI than after. I'd love to know why gas engines are putting out more soot now, maybe I'll try to do some research (searching) later.

        So yeah, the gap of average emissions between gas and Diesel is closing right now, as more DI gas engines go out. That doesn't mean it's closed though nor does it mean it will close before gas DI reverses course and goes back in the direction of PM reductions.
        • 4 Years Ago
        I'll give you one of the links I was looking at as a starter,
        http://www.cambustion.com/sparkignition
        quote - "The adoption of Gasoline Direct Injection (GDI) engines is compelling for fuel economy reasons. Since the gasoline vapour no longer has to enter through the inlet valve, a larger volume of air is able to enter in the same time. This, coupled with the charge cooling effect as the gasoline vapourizes in the cylinder, allows the engine to be downsized for equivalent power. (These advantages effectively result in improved volumetric efficiency). Turbo charging is an attractive option for enhancing power output.

        However, the lack of a hot inlet valve to vaporize the gasoline, and the reduced time available, leads to imperfect vaporization and variations in local Air Fuel Ratio. Where a locally rich zone occurs, either through excessive gasoline in vapour form, or through liquid droplets of gasoline which oxidize in a rich condition at their surface, incomplete combustion results in the production of particulates." -

        Particulate filters and other emissions technologies that are currently used by diesels are being talked about to bring down the PM levels of GDI engines. However, those aren't going to be free upgrades, just as they weren't on diesels. As we start having to use similar technologies on both diesel and gas engines, the cost difference for diesels will begin to close and make diesels that much more attractive.

        As it stands now, diesels have to use much more complicated(and expensive) emissions cleaning technology, but as GDI engines become more prevalent and emissions standards continue to tighten, that's going to be the new reality.

      you stick with your japanese cheap clones.. sorry i thought that crz was a mazda at first from the front..

      and i'll stick to the higher grade volkswagens.. more mpg, higher quality.. and the volkswagen scene is much better then the honda scene.

        I would hope the extra 10 thousand for a Jetta would net you some better plastic on the dash.

      I would be interested in seeing what a new set of tires and brakes would do for it aswell as some small mod's, I really want to see what VW could have sold us but left behind if you catch my drift.

      I saw a CR-Z on the road recently, and to me, the rear quarters look more awkward in real life than in pictures. Not quite as weird as a Renault Avantime, but kinda like that.

      Why not a base model Golf TDI w/ 6spd manual?

      You'd take some load off the brakes by downshifting and you'd get a better feel against the 6spd in the CRZ.
