AC Schnitzer's 'Tune it! Safe!' Police Vehicle

”tune safe”

"Only serious and safe tuning will bring the driving fun you want!" Under this motto, the Association of German Vehicle Tuners (VDAT) launches a special concept car every year. In 2013, BMW AG is a partner in the Association's "TUNE IT! SAFE!" initiative, which is supported by the Police and the Federal Ministry for Transport, Construction and Road Development. The Aachen-based BMW tuning specialist AC Schnitzer was responsible for most areas of tuning in the BMW 428i Coupé. As in the previous four years, a police vehicle was professionally modified for the campaign.

”tune safe”

The AC Schnitzer "ACS4 2.8i Coupé" based on the BMW 428i Coupé shows that safe tuning is far from boring. VDAT-member AC Schnitzer has upgraded the 2.8i engine to 216 kW/294 HP and 420 Nm. The police vehicle now accelerates from 0 to 100 km/h in 5.7 seconds, capable of even the fastest pursuit.

An acoustic and visual highlight is the AC Schnitzer twin sports rear silencer of stainless steel with the new chromed "Evo Racing" tailpipe trims.

The latest AC Schnitzer Type VIII Lightweight Forged Wheels in 9.0J x 21" are fitted with "Ventus S1evo" tyres in 245/30 ZR 21 91Y from TUNE IT! SAFE! chief sponsor Hankook. The low, safe road position is ensured by the AC Schnitzer racing suspension, adjustable in compression and rebound stages, from the Aachen company. Front spoiler, rear diffuser, rear spoiler and rear roof spoiler complete the aerodynamic conversion.

In the interior, the guardians of law and order can enjoy aluminium pedals, foot rest and "Black Line" handbrake handle, and the new key holder. Velours floor mats complete the interior styling. The concept car impressively demonstrates large parts of the AC Schnitzer tuning range, all of which are available commercially and of course TÜV-approved.

”tune safe”

The TUNE IT! SAFE! 428i Coupé by AC Schnitzer is no pure show car however: it is fully usable, and has been optimised in many areas. For example, the performance upgrade has improved the CO2 value per HP, and the efficiency of the engine has been optimised. The forged alloys Type VIII reduce the rotary forces by a perceptible 100 kg, which in conjunction with the height-adjustable racing suspension, ensures significantly improved driving qualities. We call this Efficient Performance by AC Schnitzer

I would like to have their tune if it was not so damn expensive. 4200 euros.

A bit, if those wheels aren't forged they are likely 30-33lbs a pc, even if forged they are likely heavier than stock.

With 294 HP I would expect it to do better than 0-100kph in 5.7. Didn't the 328i run that in around the same time? What am I missing?

Seems to be proof the angular momentum created when attempting to turn those big heavy rims at ever increasing rotational speed over a time is sapping the performance and the engine's ability to do so. Funny how that was picked-up on by all immediately. Before I started reading replies I thought to myself, "nice looking rims, but the reality is they're heavy and with nearly no sidewall to the tires they'd get destroyed quickly; it should be running plain steel wheels in reality". -lol

What I wanna know is why is an AMG tuned 2.0L you can buy from the factory achieving well over 300hp and a BMW engine not coming close? I consider BMW to be the premier leaders in hp/liter. Ok, ok, that was in the NA days. But, What happened? Why not coming close here in the FI days?

very simple.

What is above the CLA AMG in the CLA product line? Nothing

What is above the 3/428 in the product line, The 3/435.

BMW could easily make the N20 300+hp especially as it's more like 260-270 in reality now. But it cannot trump it's big brother.

This is the same scenario of the Cayman vs 911. The Cayman has been kept down on power though it can handle more as to not upset it's slotting under the 911.

I can say confidently that BMW could make a 2.0l every bit as nasty as the AMG.

It says they are forged and lighter than stock reducing rotary force by 100kg. Not sure why they rated it at 5.7 secs which is about what a stock 328 does give or take on the driver.

It gives no specs, it could have come with 24lb 17s or 27lb 18's lol.

Imagine if it had forged 19's that weighted 19lbs a pc instead of the 21s.

Who knows how they arrived at 5.7 anyway.

If I was a betting man, and I am...LOL...I would bet they are referring to the 18s. That would be my guess. I wouldn't think AC would take a base model and dress it up. Then again I don't win all bets so I could be wrong as like you said they don't give much info.

What you describe is the thinking of BMW, the manufacturer. No disagreement.

But this is AC Schnitzer, the tuner, here. Even if this is "tuned with safety" are we to assume the AMG is not? And isn't nasty'ed-up with safety? And won't have longevity? Certainly, no! So, why the sub-mid-300hp here?

The AMG engine is in house engineered and designed from the start for such a power level. This is very different than a tune which just cranks up the boost on an otherwise standard production engine. Take the base CLA engine and tune it, you would have something more in line with what AC has done here. If AC had a bigger R&D budget and wanted to price this car higher, they could have done a full build of internals similar to the AMG engine and run similar boost nearing 30lbs. But again, why do all that when they can start with the N55.

If we want to see how far we can take just a tune, BMS has shown 300whp with only exhaust work and a mix of 91/e85. But will it meet longevity and durability targets of a production engine from BMW, doubt it.

So again, lets compare apples to apples. BMW does not offer a true in house performance M engine in 4 cylinder guise like AMG has done. Be sure, that if they did it would be competitive as most any MB engine has been equalled or better by BMW. I find drivetrains to be BMWs strong suit.
