BMW reminds us what made the original M3 so great

Just because many are slavering for the global debut of the 2016 BMW M2 at the Detroit Motor Show doesn't mean BMW will let us forget the coupe that gave the letter "M" its global moxie: the M3. The Roundel has posted the first in a five-part series devoted to that seminal M, the 1987-1991 E30. Built as a homologation requirement for the race car BMW needed to beat Mercedes 190E 2.3/16V in the German Touring Car Championship, it was 1.5 times more expensive than the 325i of the time and company sales heads had doubts about being able to sell all 5,000 of them. As we know, that story had a happy ending. The first models came with a 2.3-liter four-cylinder with 195 horsepower, a chopped and tuned combination of the four-cylinder M10 block first used in 1962 and in Formula 1, with a cylinder head from the six-cylinder M88 that did duty in the M1. By the time the M3 Sport Evolution models marked the end of the first-gen production run, displacement had risen to 2.5 literz and output to 238 hp, but more important than those numbers were the phenomenal handling and relentless race victories. You should definitely check out the video above for BMW's peek into the backstory of the fourth M car after the M1, M535i, M635 CSi, and M5, and arguably most important. But if your M-centric tastebuds prefer a more modern take on the German brand's most driver-friendly vehicles, take a look at the videos below. Related Video:

AC Schnitzer packs 400-hp, tri-turbo diesel into 1 Series

At first blush, this might look like your run-of-the-mill BMW 1 Series, maybe with a few modifications. What you're actually looking at is a monster hot hatch with 400 horsepower and 590 lb-ft of torque. From a diesel. For this year's Essen Motor Show – Germany's equivalent to SEMA – the Bimmer specialists at AC Schnitzer prepared the ACS1 5.0d concept you see here. Its selling point (if only it were for sale) is the combination of BMW's most powerful diesel engine and its smallest model. It utilizes the 3.0-liter triple-turbocharged inline-six diesel engine from the M50d versions of the 5 Series, X5, and X6 sold in Europe. That engine is normally rated at 376 hp and 545 lb-ft, which is already a ton of muscle. But Schnitzer has bumped up the output on both counts, and slotted it into a 1 Series hatchback. The result is a 0-62 time of just 4.5 seconds, leaving the M135i and M235i in a cloud of diesel soot. Of course, Schnitzer has plenty more to showcase at Essen this year, including modifications for the 3 Series, X6 M, and Mini JCW. And you can bet all the other major European tuners will be on hand at the expo to show their wares, too. But as far as outlandish creations go, this monster diesel hot hatch is what's caught our attention. Compact and incredibly powerful The 1-series by AC Schnitzer with impressive motorsport quality At first sight, you do not expect brute force from the BMW 1-series. So the performance of the compact Bavarian after the AC Schnitzer tuning experts have equipped it with the M50d power plant and impressive performance upgrade, is even more incredible. Originally designed for the 5-series, the "Diesel M-Technik" pack propels the 1-series a long way forward. The smallest BMW series now has an impressive drive concept from AC Schnitzer. After the performance upgrade, the concept engine of the ACS1 5.0d delivers 294 kW/400 hp and 800 Nm torque for generous thrust. Equipped in this way, it takes just 4.5 seconds to sprint from 0-100 km/h. The acceleration from 80-180 km/h is even more impressive: the ACS1 5.0d takes just 7.9 second for this. The smallest of the compacts, the 114i, is already impressive thanks to a power increase by 52 hp to 154 hp. The four-cylinder petrol engine of the 116i, thanks to motorsport technology, now delivers 204 hp instead of 136 hp. The same figure is also achieved by the 118i, which previously had 170 horses under the bonnet.
