Here’s some more information on the Proton X50, this time indirectly, from Geely. The upcoming B-segment SUV will come with two engines, a 1.5 TGDi for the flagship and the 1.5T for the Standard, Executive and Premium variants.
The 1.5 TGDi is a direct injection three-cylinder turbo engine developed by Geely and Volvo. With 177 hp at 5,500 rpm and 255 Nm of torque from 1,500 to 4,000 rpm, the X50 Flagship’s fuel consumption is officially rated at 6.4 liters per 100 km (15.6 km / l). Paired with a seven-speed wet dual-clutch transmission also seen on the CKD X70, 0-100km / h should be similar to the 7.9 seconds cited by Geely for the Binyue, aka Coolray.
More mysterious is the 1.5T engine in the rest of the range. This is because the engine will make its debut in the X50, and prior to the media preview last week, many were unaware of its existence. What we know officially so far is that it is a port injection version of the 1.5 TGDi three-cylinder turbo, it has 150 PS / 226 Nm and the claimed fuel consumption is 6.5 liters per 100 km (15.4 km / l).
Well here’s Geely to shed some light on the new 1.5T engine, for the first time. In an article focusing on the 1.5TD engine range and interviewing Hakan Sandquist, Geely’s powertrain strategy director at CEVT, the company explained the rationale behind the 1.5TD engine family, which houses the two engines. of the X50.
We’ll delve into the company’s reasons for downsizing and three-cylinder downstream, but here are the origins of the 1.5T and 1.5TD engine family. The 1.5TD range was jointly developed by Geely and Volvo at Volvo’s R&D center in Gothenburg, CEVT China Euro Vehicle Technology in the same Swedish city and the Geely Research Institute in China. The Volvo Engine Architecture (VEA) developed by Volvo under Geely’s direction forms the basis of the 1.5TD.
The 1.5TD range was designed to withstand electrification (Mild Hybrid, Hybrid, Plug-in Hybrid) and currently, the Modular Engine Series has three basic variants. The range starts with the 1.5T PFI, which is the 1.5T in the X50. PFI stands for Port Fuel Injection. Next up is the 1.5TD using direct injection – this is the 1.5 TGDi in the flagship X50.
Lastly, there is a Miller 1.5T. Designed specifically for hybrid applications, the variable valve timing on this PFI mill is adjusted to allow the engine to run on the most fuel efficient Miller cycle.
The three engines in the 1.5TD family are 1,477cc three-potentiometer turbos with similar bore and stroke measurements of 82mm and 93.2mm. What differs is the compression ratio, which is expected due to the different fuel injection systems: it is 10: 1 for the 1.5T PFI, 10.5: 1 for the 1.5TD (1.5 TGDi) and 11.5: 1 for the 1.5 T Miller PFI.
Geely has also shared the engines’ Minimum Brake Specific Fuel Consumption (BSFC), which is 238 g / kWh for the 1.5T PFI, 232 g / kWh for the 1.5TD (1.5 TGDi) and 220 g / kWh for 1.5T. Miller PFI. BSFC is used to compare the fuel efficiency of internal combustion engines – the lower the figures, the better.
Lastly, power and torque outputs. The 1.5T starts with 150 PS (110 kW) at 5,500 rpm and 226 Nm of torque available from 1,500 to 4,000 rpm; the 1.5TD (1.5 TGDi) generates 179 PS (132 kW) at 5,500 rpm and 255 Nm of torque from 1,500 to 4,000 rpm; while the 1.5T Miller is good for 143 PS (105 kW) at 5,500 rpm and 215 Nm of torque from 2,500 to 4,000 rpm. The 1.5TD figures will be 177 PS (130 kW) if adjusted for RON 92 gasoline, and 177 PS is what Proton is quoting.
There you have it, an official mention of Geely’s 1.5T PFI engine and its lineage. This also proves that the 1.5T is a global engine from Geely-Volvo’s global engine family and not a “Malaysian special” commissioned by Proton for local use only.
We’ve already covered the X50 extensively from the media preview that happened last week, and you can see it here. Below are the spec-by-spec differences that we know of so far. Please note, however, that the images you see here are of the main flagship variant – Proton has yet to reveal the other variants in metal.
