Report – Santa Fe Is CUV of Texas
The all-new 2013 Hyundai Santa Fe has been named the 2013 “CUV of Texas” by the Texas Auto Writers Association (TAWA). Issued at the 21th annual Texas Truck Rodeo near San Antonio, the win complements the Santa Fe Sport’s victory as “Compact CUV of Texas” in last-year’s competition.
“We are very pleased the 2013 Hyundai Santa Fe has been named ‘CUV of Texas’ and proud to see that the Santa Fe family continues its winning streak at the Truck Rodeo,” said Mike O’Brien, vice president, Corporate and Product Planning, Hyundai Motor America. “Given the fact that Santa Fe Sport was named Compact Crossover at last year’s Rodeo, TAWA members have further confirmed the amazing versatility of this crossover with its five, six or seven passenger configurations.”
Footnote – What Is CVVT?
The Lambda II 3.5-liter V6 engine under the hood of the Santa Fe pumps out 276 horsepower and 248 lb.-ft. of torque.
This powerplant features aluminum construction, dual overhead camshafts and four valves per cylinder. To maximize the power spread, the engine utilizes CVVT on intake and exhaust camshafts and a three-step VIS that helps cylinders breathe efficiently at low and high RPM.
You have heard of variable valve timing. That was VVT. Make C Continuous and you have a great fuel-saving engineering design – Continuously Variable Valve Timing.
Different engine speeds (RPM) and conditions at idle or full operation require varying amounts of air and fuel. Traditionally, the valves are driven by a camshaft (using belts, gears, or chains) to lift for a certain duration (to allow intake of air+fuel mixture and exhaust of burnt gases) repeated over the life of the operation of the engine. This fixed or discrete system meant that the same valve lift event occurred at every engine RPM. This was inefficient, degraded Performance, and increased emissions. A continuous system on the other hand uses data from the ECM to vary the lift timing infinitely over the running of the engine through various RPMs. This is different than just a variable valve timing design in that the number of adjustments of the valves is not fixed at below a certain RPM and above a certain RPM, say 3,000, which is dual-adjustment; but continuously vary according to engine demands.
Especially on the Santa Fe engine, the timing and valve lift event are altered continuously by an electro-hydraulic setup. Mileage figures (estimated) for V6-powered Santa Fes are 20 mpg city/26 mpg highway/23 combined (FWD/AT), which bests the Ford Edge, Chevrolet Equinox and Toyota RAV4 V6 models.
