Peugeot today introduced its new 207 small car, the successor to—but not replacement for—the highly successful 206. (Peugeot produced 5.35 million 206 units in the seven years from 1998–2005).
Peugeot is introducing the 207 with a range of six engines: three gasoline, three diesels. The 207 will also receive the more advanced gasoline direct injection engines being co-developed by BMW and PSA Peugeot Citroën.
The initial gasoline engines are:
1.4-liter, 54 kW (75 hp). This engine is equipped with a special thermostat and a controlled alternator that allow it to conform to Euro 4 emissions standards. High torque (118 Nm) availability at low engine speed (3,300 rpm) ensures good driving characteristics, with fuel consumption of 6.3 liter/100km (37.3 mpg US) for the combined drive cycle and CO2 emissions of 150 g/km.
1.4-liter, 65 kW (90 hp). Maximum torque is 133 Nm at 3,250 rpm, but from 2,000 rpm, 90% of the maximum torque (120 Nm) is available. The engine features double overhead camshafts and 4 valves per cylinder with a variable valve timing (VVC) system on the inlet camshaft. The timing variation occurs one degree at a time and improves overall engine efficiency, increasing power and reducing fuel consumption.
For example, the combined drive cycle registers 6.2 liter/100km (38 mpg US) (146 g/km of CO2) with the 2-Tronic electronically controlled manual gearbox.
The 2-Tronic provides two gear change modes. Automated mode requires no manual gear changes and provides fully automated driving, thereby optimizing fuel consumption (a gain of 0.2 liter/100km in the combined drive cycle). Sequential mode supports manual gear changes with two control paddles under the steering wheel or the gear lever.
1.6-liter, 80 kW (110 hp). This engine develops a maximum torque of 147 Nm at 4, 000, but can provide 85% of that from an engine speed of only 2,000 rpm, and 95 % of the maximum torque, or 140 Nm, from 3,000 to 5,000 rpm. The engine offer fuel consumption of 7 liters/100km (33.6 mpg US) in the combined drive cycle (166 g/km of CO2).
The first two engines from the partnership with BMW this year are projected to be 1.6-liter models. The first will be a 4-cylinder 1.6-liter gasoline direct injection (120 bar) engine with a low pressure Twin-Scroll turbocharger (0.8 bar). This engine will develop a maximum power of 110 kW (150 hp) and a maximum torque of 240 Nm.
With the same capacity but without a turbocharger, the second engine will also have double overhead camshafts and sixteen valves; however, this engine will be fitted with continuous variable valve timing for the inlet and exhaust valves. As on the other engine, a switchable water pump and controlled oil pump help optimize fuel consumption. The maximum power will be 85 kW (115 bhp) with a maximum torque of 160 Nm.
The diesel range features three HDi engines and a diesel particulate system:
1.4-liter, 50 kW (70 hp). The engine uses a low-inertia turbocharger with a speed of rotation of up to 240,000 rpm. The common rail high-pressure direct injection system can provide injection pressures vary between 300 and 1,350 bar depending on the demand formulated by the electronic control unit (ECU). Fuel consumption is 4.5 liters/100km (52 mpg US) in the combined drive cycle, or 120 g/km of CO2.
1.6-liter, 66 kW (90 hp). The main engine in the diesel range, this engine features an aluminium engine block, sixteen-valve cylinder head and an injection system with a maximum pressure of 1,600 bar.
Developing the maximum torque of 215 Nm from only 1,750 rpm, it features injectors equipped with six very small diameter apertures ensuring efficient fuel/air mixing, multiple injections per engine cycle and a controlled turbocharger. Fuel consumption is 4.5 liters/100km (52 mpg US) in the combined drive cycle, or 120 g/km of CO2.
1.6-liter 80 kW (110 hp). The higher-end diesel is also fitted with a particulate filter. It features a variable geometry turbocharger for improved response and an overboost function that allows a temporary increase in torque from the maximum sustained 240 Nm at 2,000 rpm to 260 Nm. Fuel consumption is 4.8 liters/100km (49 mpg US) in the combined drive cycle, or 126 g/km of CO2.
