HYUNDAI TIBURON: DRIVING IMPRESSIONS

 

Hyundai's boast that the Tiburon SE can hold the road as well as European sports cars might be going a bit far, but the road-holding is quite good for the price, so good you forget there's just 172 horsepower. The redline on the tach is 6500, but the V6 will rev to 7000 before the rev limiter cuts the engine, and it sounds so good you often want to take it that far.

The aluminum double-overhead-cam V6 is mounted transversely. It makes 181 pound-feet of torque, it's all there at a low 3800 rpm, and that means a lot. Cruising along at 75 mph in sixth gear, 3500 rpm, you can mash the throttle without downshifting, and the SE accelerates well; of course, it'll squirt away better if you downshift to fifth.

Even with only 181 pound-feet of torque, the torque steer from the front-wheel drive is noticeable.

The gearbox is good, but the shifts aren't so sharp because the lever has a long throw and the linkage isn't as tight as it might be. However the clutch action is smooth, especially on the upshifts, and that compensates a bit for the long throw; so overall, the upshifts work.

We can't say the same for the downshifts, at least not with heel-and-toe downshifting, because the gas pedal is quite a bit lower than the brake pedal. So you can't fit the toe of your foot on the brake pedal and your heel on the gas. As serious as Hyundai was about the track-tuned suspension, it's surprising they missed something simple like the pedal position for sporty downshifting.

The ratios are fine; sixth gear is a tall overdrive designed to deliver better fuel mileage. It’s basically an extra gear on top, because the ratio of fifth gear (0.86:1) is almost the same as the fifth gear (0.84:1) in the five-speed gearbox on the GS model. Still, the SE has the lowest fuel mileage (18 city, 26 highway) among the Tiburons.

THE FUTURE OF THE INTERNAL COMBUSTION ENGINE

 

Carlos Ghosn, the CEO of Nissan and Renault, has proclaimed that battery-powered vehicles will account for 10 percent of global new-car sales by 2020. Mr. Ghosn, of course, is planning to introduce at least four electric cars in the next three years. Independent analysts, however, consider that battery-powered vehicles will remain at less than 1 percent of the new-car mix in 2020.

The fact is that electric vehicles are too expensive today and will remain so for some time. Moreover, electric vehicles are unproven in the real world. If carmakers are going to bet their futures on this technology, they will do so very gradually. Despite the green hype, internal combustion engines will keep powering vehicles for the foreseeable future.

But they won’t be the same IC engines that power vehicles today. With federal fuel-economy standards getting tougher by 35 percent over the next five years, IC efficiency must improve considerably.

After speaking with key powertrain engineers and some independent inventors, we’ve examined some of the technologies that can achieve this improved efficiency.

Current Solutions

Direct Fuel Injection

Direct injection (DI) costs more than port injection because the fuel is sprayed at 1500 - 3000 psi rather than 50 - 100 psi, and the injectors must withstand the pressure and heat of combustion.

But DI has a key benefit: by injecting fuel directly into the cylinder during the compression stroke, the cooling effect of the vaporizing fuel doesn’t dissipate before the spark plug fires. As a result, the engine is more resistant to detonation - a premature and near-explosive burning of the fuel, producing a knocking sound and pounding the pistons with pressure and heat - and can therefore operate with a higher compression ratio - about 12:1 instead of 10.5:1. That alone improves fuel economy by two to three percent.

And DI also offers the possibility of lean combustion because the fuel spray can be oriented so that there is always a combustible mixture near the spark plug. That could yield five percent more efficiency.

Several European carmakers are already using this lean-burn strategy. Unfortunately, lean combustion causes higher tailpipe emissions of NOx. New catalysts promise to reduce emissions. Meanwhile, we expect direct injection to become universal by 2020.
