Hyundai goes high tech to reach mainstream fuel economy numbers

Hyundai may have been burned back in 2011 for fudging the numbers when it comes to fuel economy, but the company is doing its best to show that it can still make fuel efficient vehicles with the next generation Sonata.
 
While the 2015 Sonata was first unveiled back in April at the New York Auto Show, the newly announced Eco model will carry the crown as the most efficient trim level for the Sonata (at least until the new hybrid variant arrives). The Sonata Eco uses a 1.6-liter turbocharged four-cylinder engine that generates 177hp and 195 lb-ft of torque.
 
Instead of going with a traditional “slush box” transmission, the engine is paired with a 7-speed dual-clutch transmission (DCT), which Hyundai says is a first in the mainstream midsize sedan market.

 
When the numbers are added up, the Sonata Eco will deliver 28 mpg in the city, 38 mpg on the highway, and 32 mpg combined. This represents a 10 percent improvement over the 2015 Sonata SE with its 2.4-liter, 185hp engine.
 
It should be noted that Nissan and Mazda are able to achieve similar fuel economy to the Sonata Eco with more powerful, less complex engines in the Altima and 6 respectively. Both competitors also used tried and true transmissions (a CVT for the Altima, and a 6-speed automatic for 6) instead of a more complex (and often times “jerky” at low speeds) DCT.

 
The 2015 Sonata Eco will have a base price of $23,275 with the only option being a $4,100 Technology Package which includes such niceties as Blind Spot Detection, Rear-cross Traffic Alert, Lane Change Assist, push-button start, dual-zone automatic climate control, 8” navigation screen, and a hands-free auto open trunk.

The biggest issue is that they are throwing in a lot tech to achieve numbers that simply aren't mind blowing.

A lot of tech ? How is a 'puter operated manual transmission more "tech" than a CVT (even w/dual clutches) ? Or how is a turbo "tech" at all ? All are pretty common fare these days. A better question might be why isn't Hyundai reaping the same benefits for the cost of their chosen tech as does ... say Ford ? For that matter what is the added cost to Hyundai of this "tech" vs what Nissan etal are doing ? Perhaps less than the cost of Mazda's conventional transmission and a GDI engine ? How much tech went into making the 6's chassis lighter and more fuel efficient ?
