Tatra V10
V10 966ci 283Hp and 745ft-lb
Making air-cooled large truck diesel engine – that’s Tatra’s tradition. The Model T815, which can have two, three or four axles, has been powered by various engine layouts, including V10. The V10 is the middle step between V8 and V12 variants and has been used since 1983. Except the turbocharged V12, they are naturally aspirated and all are air-cooled which is the reason why are they so loud. And the V10 sound awesome, of course.
Cummins 6BT 12V
Inline-6 350ci 160-215Hp and 440ft-lb
By browsing forums, you’d find out that many people agree the 12-valve Cummins sound great, even better than the larger 24-valve. The 12V Cummins came out at the end of the 80s ready to power mainly light and medium duty trucks, but also selected heavy ones. It also became a popular option in the Dodge Ram as it produced more torque at low revs with significantly better fuel consumption than an alternate rival gasoline V8.

Detroit Diesel Series 60
Inline-6 700/778ci 390-455Hp and 1550lb-ft
Amongst the popular two-strokes, there are also four-stroke Detroit Diesels, like the Series 60. The first unit they used had a volume of 11.1 litres and it was discontinued after 12 years. Before that, a larger 12.7-litre version was introduced and became very popular as an on-highway engine. With that, the DDEC system has been used as a form of ECU with additional functions useful to the driver, such as automatic stall prevention, engine diagnostics etc.

Chevrolet Duramax LB7
V8 403ci 300Hp and 520ft-lb
Chevrolet’s Duramax series of V8 diesel engines has been launched with the LB7 variant. The LB7 succeeded the outdated Detroit Diesel V8 and it was one of the first engines in America of this kind to accommodate common-rail direct injection. However, that also brought it many problems with reliability as injector failure was the most common issue. It occurred so often that Chevrolet had to recall them and install newly designed units inside.

Mack E9
V8 998ci 610Hp and 2,250 ft-lb
When somebody knows about Mack, it is certain the E9 engine will be topic talk about. According to what people say it is very powerful and high-torque engine returning decent fuel economy. The Mack E9 V8 was a on-road engine for heavy duty trucks rated class 8 with a gross vehicle weight rating over 33,000 lb, like a regular 18-wheeler. Mack had couple of such trucks, for example, the Superliner, Ultraliner and Titan.
Scania V8
V8 998ci 730Hp nad 2,600ft-lb
With only a little bit of general knowledge, you should know that Scania and V8 are terms that cannot be separated. By the end of the 1960s, Scania introduced their first diesel V8 engine which supposedly was the most powerful truck power plant in Europe. So far the legend is still living on with the Scania DC16 which now has more than double the power of the very first engine displacing 14 litres. Besides the new 16.4L power unit, there’s also a 15.6L version being used.
Tatra V12
V12 1.160ci 320Hp and 955ft-lb
Earlier Tatra V12 T930E engine was hooked up to the Tatra 813. However, that was an older unit and the upcoming range of engines had more power and most notably more torque. OHV, air cooling, non-turbo – like the V10 it still had only basic features, but believe or not it was enough to move up to a 28 ton heavy loaded vehicle. Not only move but also off-road with it. Later on, there was also the turbocharged V12 revealed with twin-turbos making 360Hp.
Ford Powerstroke 7.3
V8 444ci 275Hp and 525ft-lb
Introduced in 1995, the Powerstroke was an engine made for the Ford Super Duty vehicles. It started with a 7.3L version making 250Hp with an automatic gearbox and 175Hp with a manual replacing the outgoing 7.3 IDI engine. The engine had a direct injection system called HEUI which stands for hydraulically actuated electronic unit injection. It took 13 more years for Ford to incorporate the common-rail technology int their Powerstroke engines.
Detroit Diesel 8V-71
V8 568ci 318Hp and 866ft-lb
Yes, a two-stroke Detroit Diesel again. But this isn’t one of those extreme multicylinder powerhouses that could move a building. It is instead a regular V8 which was used in highway vehicles, such as buses and medium duty trucks, with a little stronger oomph than the six-cylinder version. The specs on the chart are for naturally aspired version while there was also a turbocharged and intercooled variant making 195ft-lb more.
Caterpillar 3408
V8 1.098ci 500Hp and 2.000ft-lb
The caterpillar 3408 is often compared to the Mack E9. They were used roughly at the same time and were meant for the same truck class. But the Cat was also used as a marine engine and even though it had a bigger displacement, it didn’t make any more power. Allegedly, it didn’t sound as great, had worse fuel economy and its crankshaft would snap with raising power figures. You can find it in the Australian Kenworth W900 and some Peterbilt trucks.
