The results of the 2007 International Engine Of The Year awards are out. The question everyone will be asking is – will the BMW 5.0 litre V10 be able to persevere and continue it’s reign as the award winner for the third time consecutively this year? Or will it be out-triumphed by a rival from another manufacturer, or perhaps another engine from BMW’s own stables? We find out what the results are after the jump!

Overall International Engine Of The Year

1. BMW 3-litre Twin Turbo (335i) 395
2. Volkswagen 1.4-litre FSI (TSI) (VW Golf, Touran, Jetta) 259
3. Porsche 3.6-litre Turbo (911 Turbo) 252
4. BMW 5-litre V10 (M5, M6) 241
5. Volkswagen/Audi 2-litre Turbo FSI 154
6. BMW-PSA 1.6-litre Turbo (Cooper S, Peugeot 207) 135
7. BMW 2.5-litre 6-cylinder (325, 525, Z4, X3) 58
8. Toyota 1-litre 3-cylinder (Aygo, Yaris/Echo/Vitz, Citroen C1, Peugeot 107) 56

There you go, the BMW M5’s V10 engine has been upstaged by it’s own team mate the 3.0 litre N54 Twin Turbo, and has dropped to fourth position behind two other German rivals. It’s interesting to note that almost every engine in the Overall Winner contenders list are German, with one engine being half-French and the other one Japanese. The N54 Twin Turbo uses twin parallel turbochargers, each fed by a bank of 3-cylinders. It is also the first application of BMW’s new high-precision direct-injection system. Despite being turbocharged, the N54 Twin Turbo has an unusually high compression ratio of 10.2:1. Performance stats result in 302bhp peak power, and 400Nm between 1,300rpm and 5,000rpm. The engine revs all the way to 7,000rpm.

Best New Engine of 2007

1. BMW 3-litre Twin Turbo (335i) 446
2. Lexus Hybrid 5-litre (LS600h) 183
3. BMW-PSA 1.6-litre Turbo (Cooper S, Peugeot 207) 159
4. Renault 1.2-litre Turbo (Clio) 75
5. Porsche 4.8-litre Turbo (Cayenne) 66
6. Lexus 4.6-litre (LS460) 62

There are a few new engines this year – the new Lexus Hybrid in the flagship LS, the 4.6 litre mated to the 8-speed auto in the LS460L, Renault’s new small displacement turbo, Porsche’s new direct injection-equipped turbocharged 4.8 litre in the Cayenne Turbo, and BMW’s new sweet 1.6 litre Turbo shared with PSA Peugeot Citroen.

Best Fuel Economy

1. Toyota Hybrid 1.5-litre (Prius) 244
2. Honda Hybrid 1.3-litre IMA (Civic) 130
3. Fiat-GM Diesel 1.3-litre (Panda, Grande Punto, IDEA, Doblo, Lancia Ypsilon, Suzuki New Ignis) 118
4. Volkswagen 1.4-litre FSI (TSI) (VW Golf, Touran, Jetta) 111
5. BMW Diesel 3-litre Twin Turbo (335d, 535d) 90
6. Mercedes-Benz Diesel 3-litre (C, E, S, CLS, G, R, ML, GL, Chrysler 300C, Jeep Grand Cherokee, Commander) 45

The engine under the hood of the Toyota Prius has claimed this award for the fourth year straight. And what a victory it has this year, with nearly double the points of the second place winner, the Honda IMA Hybrid. However, in a sea of diesel and hybrid engines, one lone petrol engine holds it’s fort – Volkswagen’s 1.4 litre TSI which uses both supercharging and turbocharging came in 4th.

Best Performance Engine

1. BMW 5-litre (M5, M6) 219
2. BMW 3-litre Twin Turbo (335i) 185
3. Ferrari 6-litre (599 GTB) 170
4. Porsche 3.6-litre Turbo (911 Turbo) 97
5. Mercedes-AMG 6.2-litre (CLK, E, CLS, S, ML, R) 67
6. Mercedes-AMG 6-litre bi-Turbo (SL65, CL65, Maybach) 66

Best Performance Engine is of course the 5.0 litre V10 from the M5 and the M6, making 507 horsepower and 520Nm of torque. This year it was toppled by the 3.0 litre N54 Twin Turbo in the overall category, but managed to trump it in the performance category. Will it be able to hold it’s fort against the new BMW 4.0 litre V8 from the new E92 M3 next year?

Best Sub-1 Liter Engine

1. Toyota 1-litre (Aygo, Yaris/Echo/Vitz, Citroën C1, Peugeot 107) 254
2. Smart Diesel 799cc (Smart Fortwo) 190
3. Mitsubishi 999cc Turbo (Smart Fortwo) 163
4. Ford 1-litre Supercharged (EcoSport) 128
5. Mitsubishi 999cc (Smart Fortwo) 95
6. Suzuki 1-litre (Wagon R+) 85

Toyota’s 1.0 litre engine in the Aygo and it’s french brothers the C1 and the 107 makes 67bhp and 93Nm at 3,600rpm, figures that are not bad at all for a 1.0 litre car. It is known to be the lightest combustion engine on sale today, weighing only 69kg thanks to special weight-saving construction. The engine is all-aluminium, and the throttle body and fuel pipe is made out of resin instead of metal.

Best 1 Liter to 1.4 Liter Engine

1. Volkswagen 1.4-litre FSI (TSI) (VW Golf, Touran, Jetta) 404
2. Honda Hybrid 1.3-litre IMA (Civic) 178
3. Fiat-GM Diesel 1.3-litre (Panda, Grande Punto, IDEA, Suzuki New Ignis) 160
4. Renault 1.2-litre Turbo (Clio) 123
5. Peugeot-Citroën/Ford Diesel 1.4-litre (Citroën C2, C3, Ford Fiesta, Fusion, Mazda 2/Demio, Peugeot 1007, 207, 307) 66
6. BMW-PSA 1.4-litre (MINI One) 56

The only non-hybrid and non-diesel engine in the Fuel Economy category tops the 1 litre to 1.4 litre category – Volkswagen’s 1.4 litre TSI. The engine employs both supercharging and turbocharging, a method Volkswagen calls Twincharging (TSI stands for Torque Strong Twincharger), to make 170 horsepower and 240Nm of torque from a 1.4 litre engine. A lower boosted 140hp variant is available too.

Best 1.4 Liter to 1.8 Liter Engine

1. BMW-PSA 1.6-litre Turbo (Cooper S, Peugeot 207) 267
2. Toyota Hybrid 1.5-litre (Prius) 251
3. Audi 1.8-litre Turbo FSI (A3) 82
4. Peugeot-Citroën/Ford Diesel 1.6-litre (Fiesta, Ford C-Max, Citroën C4, C4 Picasso C5, Mazda 3, Peugeot 1007, 206, 307, Partner) 74
5. Honda 1.8-litre (Civic, Stream, FR-V) 65
6. Mercedes-Benz 1.8-litre Supercharged (C, SLK, CLK, E) 62

BMW and PSA’s nice direct injection twin scroll turbocharged 1.6 litre engine tops the 1.4 litre to 1.8 litre list. It’s used in vehicles from both marques – in the MINI Cooper S as well as the Peugeot 207 GT and GTI. Audi’s new recently launched 1.8 litre Turbo FSI comes in third, and Honda’s new R-series 1.8 litre found in our local Civic 1.8S comes in 5th place. The M271 1.8 litre Kompressor engine from Mercedes Benz comes in at 6th place.

Best 1.8 Liter to 2 Liter Engine

1. Volkswagen/Audi 2-litre Turbo FSI (A3, A4, A6, TT, Golf GTi, Eos, Jetta, Å koda Octavia, Seat Altea, Leon) 249
2. BMW Diesel 2-litre (X3, 120d, 320d, 520d) 143
3. Honda 2-litre i-VTEC (Civic Type R) 123
4. Honda 2-litre S2000 (Europe/Asia)) 106
5. Mitsubishi 2-litre Turbo (Evo IX, Outlander/Airtek) 81
6. Volkswagen 2-litre (GDI) FSI (Audi A3, A4, VW Golf, Touran, Eos, Seat Leon, Toledo, Å koda Octavia) 71

That lovely 2.0 litre Turbo FSI engine that performs great but doesn’t really sound that great tops the 1.8 litre to 2.0 litre list. BMW’s 2.0 litre turbodiesel comes in second place, something I’ve tried in the BMW 320d Touring test drive I wrote about recently.

Best 2 Liter to 2.5 Liter Engine

1. BMW 2.5-litre (325, 525, Z4, X3) 179
2. Subaru 2.5-litre flat four Turbo (Forester, Impreza) 150
3. Mazda 2.3-litre GDI Turbo (3MPS, 6MPS, CX-7, MPV) 144
4. Honda Diesel 2.2-litre (Civic, Accord (Europe), CR-V, FR-V) 119
5. Toyota Diesel 2.2-litre D-CAT (Avensis, RAV4, Auris, Lexus IS220d) 104
6. Fiat Diesel 2.4-litre JTD Multijet (Alfa 166, Lancia Thesis, Croma, Alfa 159, Brera) 101

This category is topped by BMW’s 2.5 litre straight-six engine, something that many consider to be the sweet spot in BMW’s engine offerings in terms of the best balance between price versus performance. The 325i and 525i are favorites among buyers of both the 3 and 5-series here in Malaysia, and even BMW Malaysia has chosen to equip both the 2.5 litre cars with M Sport bodykits. It is the only normally aspirated engine in this list full of both gasoline and diesel turbos, which shows that although BMW has been making waves with turbocharging recently, it still does know how to properly do a fantastic normally aspirated engine.

Best 2.5 Liter to 3 Liter Engine

1. BMW 3-litre Twin Turbo (335) 383
2. BMW Diesel 3-litre Twin Turbo (335d, 535d, X3) 254
3. BMW 3-litre (Z4, 330, 530, 630, 730) 98
4. Audi/VW Diesel 3-litre V6 (A4, A6, Allroad, A8, Q7, Touareg, Phaeton) 96
5. Porsche 2.7-litre flat six (Boxster, Cayman) 95
6. Honda Hybrid 3-litre V6 (Accord) 79

The N54 Twin Turbo tops this list as well, so let’s have a look at all the engines it defeated. In second place comes that equally impressive 3.0 litre sequential twin turbochaged diesel engine from BMW, which comes in the 335d and 535d as well as the X3 3.0sd top of the range. Number 3 is a BMW as well – the 3.0 litre normally aspirated engine comes in a few power configurations from about 250 hp all the way up to 272hp.

Best 3 Liter to 4 Liter Engine

1. Porsche 3.6-litre Turbo (911 Turbo) 224
2. BMW 3.2-litre (Z4 M) 220
3. Toyota Hybrid 3.5-litre V6 (GS450h) 187
4. Porsche 3.8-litre (911) 118
5. Audi 3.6-litre FSI (Q7, VW Touareg, Porsche Cayenne) 68
6. Toyota Hybrid 3.3-litre (Lexus RX400h) 65

Porsche’s nice new twin VGT turbocharged 3.6 litre boxer tops this list. It is the first and only turbocharged gasoline engine in the world at this moment to use Variable Geometry Turbochargers to feed boosted air into the hungry combustion chambers. The old 3.2 litre from the E46 M3 lives on, placed second in this particular chart in it’s application in the BMW Z4 M Coupe and Roadster.

Best Above 4 Liter Engine

1. BMW 5-litre V10 (M5, M6) 269
2. Ferrari 6-litre (599 GTB) 155
3. Lexus Hybrid 5-litre (LS600h) 132
4. Audi 4.2-litre FSI (A6, A8, Q7, RS4, R8) 104
5. Mercedes-AMG 6.2-litre (CLK, E, CLS, S, ML, R) 77
6. Mercedes-AMG 6-litre Bi-Turbo (SL65, CL65, Maybach) 59
