BMW totally owned the 2006 International Engine Of The Year awards again, just as it did last year. It’s 5.0 litre V10 engine used in the BMW M5 and BMW M6 won both the Best Performance Engine Award as well as the overall International Engine Of The Year 2006 award for the second year in a row. BMW also won 3 other awards, the 3L to 4L category with it’s BMW Z4M/E46 M3 3.2 litre straight-six engine, and the 2.5L to 3L category with it’s 3.0 litre twin turbodiesel engine. That makes BMW’s total award count at a nice number 5. Let’s have a look at the engines that won awards in the International Engine Of The Year Awards 2006.

Best New Engine of 2006

The winner for this category is the Volkswagen’s new 1.4 litre TSI found in the Volkswagen Golf GT. The relatively small 1.4 litre engine boasts 170hp and 270Nm of torque through twincharging, a combination of supercharger and turbocharged forced induction. Through Volkswagen’s FSI Direct Injection, the engine can combine forced induction together with a high piston static compression ratio of 10:1 to produce excellent power throughout the rev range. Turbocharged cars usually need to have a low compression ratio of about 8:1 to 9:1 because of the force inducted air.

1. Volkswagen 1.4-litre TSI (Golf) 250
2. Toyota 3.5-litre V6 Hybrid (GS450h) 196
3. Chevrolet 7-litre V8 (Corvette Z06) 123
4. Mercedes-AMG 6.2-litre (CLK, ML) 117
5. Porsche 3.4-litre flat six (Cayman) 102
6. Honda 1.8-litre (Civic) 81

Best Fuel Economy

No suprise here. Toyota’s 1.5 litre Hybrid Synergy Drive has got the top position in this category for three straight years now. This engine also won the 2004 overall Engine of the Year award. The 1.5 litre hybrid powers the best-selling hybrid Toyota Prius. The gasoline 1.5 litre engine provides 76hp at 5000rpm, and it’s accompanying electric motor provides another 67hp. The hybrid system also provides a massive 400Nm of torque between 0-1200rpm, thanks to the electric motor.

1. Toyota Hybrid 1.5-litre (Prius) 196
2. Honda Hybrid 1.3-litre IMA (Civic) 127
3. Fiat-GM Diesel 1.3-litre (Panda, Grande Punto, IDEA, Doblo, Lancia Ypsilon, Opel/Vauxhall Agila, Corsa Astra, Meriva, Tigra, Combo, Suzuki New Ingis) 111
4. Honda 3-litre V6 Hybrid (Accord) 74
5. Toyota 3.5-litre V6 Hybrid (GS450h) 54
6. Renault/Nissan Diesel 2-litre (Mégane, Laguna) 49

Best Performance Engine

The BMW M5 and BMW M6’s 5.0 litre V10 packed full of Formula 1 technology takes this category with it’s 507bhp and 520Nm of torque from a 5 litre 90 degree V10 block. This engine is relatively lightweight; uses iron-coated aluminium pistons for example. Each cylinder is also fed by a dedicated throttle, giving the engine a total of 10 throttle trumpets, sucking air in from 2 intake plenums. You can treat the results table below as a yardstick of how technologically advanced the BMW 5.0 litre V10 is, the engine scored almost double the points of the Ferrari 4.3 litre V8 from the Ferrari F430 which took won the 2nd place position.

1. BMW 5-litre V10 (M5, M6) 342
2. Ferrari 4.3-litre V8 (F430) 160
3. Mercedes-AMG 6-litre bi-Turbo (SL65, CL65, Maybach) 130
4. Chevrolet 7-litre V8 (Corvette ZO6) 103
5. Porsche 3.8-litre (911) 54
6. BMW 3.2-litre (M3, Z4 M) 52

Best Sub 1-litre Engine

2006 is the 7th year that Honda’s 1-litre Integrated Motor Assist found in the Honda Insight has won the Best Sub 1-litre Engine category. The year it debuted (year 2000), it also won the Overall Engine Of The Year title. The 1-litre engine makes 68hp and 90Nm of torque in standard mode, but with the Integrated Motor Assist this power is boosted to 76hp and 113Nm of torque. This engine will also be installed into the upcoming Honda Fit Hybrid. Coming close at 239 points in 2nd place is the Toyota 1.0 litre 3-cylinder engine found in the Toyota Aygo (also Yaris, Echo and Vitz 1.0 litre models), Citroen C1 and Peugeot 107.

1. Honda 1-litre IMA (Insight) 282
2. Toyota 1-litre 3-cylinder (Aygo, Yaris/Echo/Vitz, Citroen C1, Peugeot 107) 239
3. Ford 1-litre supercharged (EcoSport) 144
4. Smart Diesel 799cc (ForTwo) 99
5. Suzuki 1-litre (Wagon R+) 94
6. Smart 698cc (ForTwo) 81

Best 1 litre to 1.4 litre Engine

The Volkswagen 1.4 litre TSI which won the Best New Engine award also took the 1 litre to 1.4 litre engine title by a close margin of 14 points more than the 2nd place winner, the Honda 1.3 litre IMA found in the Civic Hybrid. The engine’s two compressors (a supercharger and a turbocharger) operate at 1.53 bar each, producing a maximum boost of 2.5 bar at 1500rpm. This allows the engine to have 240Nm of torque at a very low 1,750rpm. This engine will be really wonderful to drive in the city. There will also be a light pressure version that makes 140hp instead of the performance version that makes 170hp.

1. Volkswagen 1.4-litre TSI (Golf) 264
2. Honda Hybrid 1.3-litre IMA (Civic) 250
3. Fiat-GM Diesel 1.3-litre (Panda, Grande Punto, IDEA, Doblo, Lancia Ypsilon, Opel/Vauxhall Agila, Corsa, Astra, Meriva, Tigra, Combo, Suzuki New Ignis) 188
4. Peugeot-Citroën/Ford Diesel 1.4-litre (Citroën C2, C3, Xsara, Ford Fiesta, Fusion, Mazda 2/ Demio, Peugeot 1007, 307) 103
5. Toyota Diesel 1.4-litre (Yaris/Echo/Vitz, MINI) 52
6. Volkswagen 1.4-litre FSI (GDI) (VW Polo, Golf) 50

Best 1.4 litre to 1.8 litre Engine

Toyota’s 1.5 litre Hybrid Synergy Drive won this category. It scored 274 points, more than double the 2nd place winner’s 129 points. Details on the winning engine can be found under the Best Fuel Economy award part of this blog post. I’d have expected Honda’s new 1.8 litre i-VTEC to score better in this category. I guess it didn’t really impress the judges. More details on the 1.8 litre Honda i-VTEC engine here.

1. Toyota Hybrid 1.5-litre (Prius) 274
2. Honda 1.8-litre (Civic) 129
3. MINI 1.6-litre Supercharged (Cooper S) 126
4. Renault Diesel 1.5-litre dCi (Clio, Modus, Mégane, Scénic, Nissan Micra/March, Almera, Tiida/Note/Versa) 110
5. Peugeot-Citroën/Ford Diesel 1.6-litre 106
6. Toyota 1.8-litre VVTL-I (Celica, Corolla Sport) 94

Best 1.8 litre to 2.0 litre Engine

The winner for this category is Volkswagen’s extremely versatile 2.0 litre turbocharged FSI engine. The engine has been used in a broad scope of applications, from performance hot hatches to low-end versions of luxury sedans with 200hp, 185hp and 170hp versions. The engine has a peak torque of 280Nm from as low as 1,800rpm with very little turbo lag and a broad torque curve. The twin-cam engine also features variable valve timing and Volkswagen’s FSI direct injection for a higher compression ratio. The 2.0 litre engine is still being developed, and Volkswagen’s engineers aim to get it to more than 300Nm of torque peaking at an engine speed lower than 1,800rpm. Some of the knowledge gained during the developedment of the Twin-charged TSI should come in handy here.

1. Volkswagen/Audi 2-litre FSI Turbo (Golf GTi , Audi A3, A4, A6, Skoda Octavia, Seat Leon) 218
2. Honda 2-litre i-VTEC (Civic Type-R) 131
3. Honda 2-litre (S2000 (Europe/Asia)) 126
4. BMW Diesel 2-litre (X3, 120d, 320d, 520d) 108
5. Renault/Nissan Diesel 2-litre (Laguna, Mégane) 97
6. Mitsubishi 2-litre Turbo (Evo IX, Outlander/Airtek) 95

Best 2.0 litre to 2.5 litre Engine

Subaru knocks last year’s winner, the 2.2 litre i-CTDi turbodiesel from Honda off it’s throne for the best 2-2.5 litre engine award this year. Subaru’s 2.5 litre 4-cylinder boxer is found in the new Subaru Impreza and Subaru Forester. It comes in either 227hp or 277hp form, and 320Nm of torque at 3600rpm. And as a boxer, it sounds great too. This category has 7 winners, with two tied in at the 6th place.

Best 2.5 litre to 3.0 litre Engine

BMW’s 3.0 litre twin turbodiesel from the BMW 535d wins this category again. The engine comes with two turbos, a smaller one and a larger one that work sequentially, with the smaller one providing low-end boost without taking too long to spool up and a bigger turbo to take on the higher rev ranges.

1. BMW Diesel 3-litre Twin Turbo (535d) 155
2. BMW 3-litre 6-cylinder (Z4, 330, 530, 630, 730) 153

Best 3.0 litre to 4.0 litre Engine

BMW’s 3.2 litre straight-six M engine was installed in the E46 BMW M3 and currently BMW’s Z4 M roadster. It’s considered BMW’s most successful engine in the awards so far, winning 8 awards so far since it’s debut in 2001. The engine makes 343bhp at 7,900rpm and 365Nm of torque at 4,900rpm. More than 100hp per litre is always admirable. It features double VANOS variable valve timing. This engine will be replaced in the upcoming E90 BMW M3 soon by a new 4.0 litre V8 derived from the M5’s 5.0 litre V10 engine.

1. BMW 3.2-litre (E46 M3, Z4 M) 235
