Comparison of atmospheric and turbocharged engines on the example of Skoda Octavia and Peugeot 407

Today, more and more manufacturers choose to equip their cars compact petrol turbo engine. What is surprising, because in comparison with atmospheric counterparts latter have better performance at smaller size and weight. Significant advantages are obvious. But is it really bleak prospect aspirated units? To answer this question, we compare the Peugeot 407 is equipped with a gasoline 2.2-liter atmospheric engine, and the Skoda Octavia with a 1.8-liter turbocharged TSi. We compare the atmospheric and turbocharged engines on the example of Skoda Octavia and Peugeot 407. Each of these competing models has its own attractive features. Peugeot 407 endowed with the flax stylish, expressive and sophisticated French Exter rum. In the guise of Skoda Octavia, for instance the contrary, is dominated by traditional Czech brand car SPO-Koine forms. However, the conservative-tive appearance Skoda Octavia has its advantages. Yielding to the Peugeot 407 in length and width, Octavia located reaches a high roof (7 inches longer), which increases ease of access to the salon. Also, Czech machine captivates the best comfort in the rear. Kupeobraznaya line wing-shek Peugeot causes too low a position above the floor hearth-nis seat second row. Because of this, the passengers sitting in the back, can not be considered optimal GOVERNMENTAL. In this case, a shortage of legroom, although the wheelbase is a French car, not the smallest in the class - 2.725 meters. Another position at which loses Peugeot 407 Skoda Octavia - is the amount of luggage. In the Peugeot 407 it is equal to 465 liters, while the Skoda Octavia, this show-Tel is 635 liters. With regard to workplace organization Bodi-Chairman, there is both a car worthy of good reviews. However, the Peugeot 407 has a gain in the width of the cabin is not in front Side-tions - 142 cm vs. 138-mi. If the estimated vat lists the equipment of cars, it is difficult to give anyone of them to excel. True, standard equipment Peugeot 407 cover exists a presence knee airbags. And of equipment Skoda Octavia include more active safety systems. Aspirated engine Peugeot 407 develops a little more power (163 l.s/5875 rpm) than the turbo-engine Skoda Octavia (160 l.s./5000 rpm). But loses him to the maximum nomu torque (224 Nm / 4,150 rpm vs. 255 Nm / 1500 rpm). The power unit of French car is passive about the low-battalions and wakes up only when the tachometer needle reaches 2000 rpm. The engine is the Czech car has a good supply of traction starting from 1000 rpm, while maintaining a working range up to 7000 rpm. Accelerating dynamics Skoda Octavia shows the complete superiority over the set Peugeot 407. Czech self-Bill quickly picked up speed from 0 to 100 km / h (7.36 seconds vs. 9.06), from 60 to 120 km / h at the third transition problem (28.42 vs. 30.23 seconds), 80 up to 120 km / h in fourth, fifth and sixth gears (6.65 / 8.73 / 10.51 vs. 9.62 / 13.92 / 18.13 seconds). Skoda Octavia also demonstrated a better elasticity engine, ahead of Peugeot 407 at kilometer segment-tion at the start from a place (29.89 vs. 33.49 seconds) and when you start at a speed of 50 km / h in fifth gear (31.1 vs. 35.24 seconds). In this case, Octavia was more economical and free-its competitor. Average consumption ben-zine Skoda Octavia was almost a liter less than the Peugeot 407 (8.7 liters vs. 9.6). However, due to the presence of a bulk fuel tank French sedan wins power reserve on one filling (688.1 miles vs. 633.9). And the Peugeot 407, Skoda Octavia and are based on platforms with multi-link construc-struction rear suspensions. The front suspension uses 407-th circuit of the double-wishbone suspension, while a Czech machine stole di installed rack McPherson. On the line both cars are very confident. However, The presence of Octavia more frisky and Al-particle engine provides it to win when the overtaking. But on a twisty track pain-Shua instills confidence Peugeot. "The Frenchman" it does what commands-hole driver, has more informa-setting and sharp steering, as well as responsive brakes. Yes, and the stability margin in high-speed rotation-max y Peugeot 407 above. Skoda Octavia demonstrates the smoother response. It is more heels, but at the same time is well predictable and enjoyable driving. Measurement of brake dynamics of the Peugeot 407 turned out to be somewhat worse than that of its eastern rival. Stopping distance of French sedan with a speed of 60/80/100/120/140 km / h was 14.7 / 26.1 / 40.9 / 59.6 / 76.9 meters. Octavia to a complete stop was Dos sufficiently 14/24, 7/38/55, 1 / 76, 1 meter. In the area of ??driving comfort both cars are about the same very good level, with the only difference being that the Peugeot 407 has slightly better sound insulation of the passenger compartment at speeds of 100 and 140 km / h. A Skoda Octavia has a slight advantage to ride. Thanks to the comparison of atmospheric and turbocharged engines for example, Skoda Octavia and Peugeot 407 the conclusion is obvious. Aspirated engine Peugeot 407 there is little unable contradicts vopostavit turbo Skoda Octavia. Powertrain of the car from Mlada Boleslav won a convincing victory with respect to the majority of key characteristics, in particular, dynamics, flexibility and cost-surface. This is just another proof that the era of atmospheric engines coming to an end. But besides, can different engine, Octavia distribution suggests other important advantages, such as high functionality and reliable behavior on the road. Among the strengths of one hundred Ron Peugeot can distinguish drown-chenny design and excellent controllability, but for the final victory they still are not enough. Specifications.
