Much to do with its unflappable dynamics is its Vehicle Stability Assist (VSA), Acura's almost imperceptible traction and yaw control. Often traction control systems, such as Mazda's TCS, installed in its new 6, or Volkswagen's ASR, cut out when the wheels start spinning creating a potentially dangerous situation, let alone ruining the enjoyment factor. The TSX never once bogged down during countless launches, some on wet road surfaces, others dry, and sometimes even during a 90-degree turn taking off from standstill at full throttle.
The engine itself is a little peaky compared to the fat torque curve of a V6, with maximum power coming on at 6,800 rpm and ultimate torque arriving at 4,500 rpm, despite the i-VTEC intelligent valve-control system broadening the power band. Still a lot of people, including myself, enjoy the high-revving excitement of a four-cylinder. Personally I thrill even more when passing the gas station time and time again. Manually equipped, the TSX achieves an impressive combined city/highway fuel economy rating of 9.7 L/100 km (25 mpg) and LEV-2 emissions rating.
