Shoehorning big engines into little roadsters is a classic operation - take the Breckland Beira V8 and Irmscher GT40 for a pair of recent examples - but the tuners at Hartge have accomplished what may be one of the most impressively OEM-looking engine swaps of recent times. The combination of BMW Z4 and M5/M6 5.0L V10 engine is inspirational, and with the car now for sale, it could be yours.

Fitting the big V10 into such a small package as a last-generation BMW Z4 may seem like an impossibility, but the photos illustrate the job was done with a level of expertise that could be mistaken for ease. Though we don't know exactly what modifications had to be made to get the big engine into the bay, it serves as some evidence that BMW's reluctance to stick the V8 from the new M3 into the next-gen Z4 for an M model is more about preserving the hierarchy than about mechanical limitations.

The car is a one-off example built for a customer, but is now available second-hand at a discount price of just €97,900 ($137,800) including VAT, with only 4,860mi (7,824km) on the odometer. The owner lists the car's fuel efficiency rating at 15.8mpg (14.9L/100km) in the combined cycle, 11.8mpg (19.9L/100km) in the city and 17.4mpg (13.5L/100km) on the highway. Those figures aren't exactly attractive with European fuel prices being what they are, but the 328g/km CO2 rating is likely to be just as painful given modern emissions charging.

Some of the other upgrades to the car include custom 20x9in and 20x10in Hartge alloy wheels, a reserved black leather interior and a full complement of luxury features like navigation and heated seats.

    Bad stuff?

  2. "more about preserving the hierarchy than about mechanical limitations"

    More than Europolititians, I'd say... My worries about this little rocket is its weight. I'd rather have a turbocharged six-cylinder engine inside an Elise.

  4. I've seen their V10 3 series swap in person and at first didn't even notice it was a swap! As to the "hierarchy", I know I will take flak for this but, IMO BMW should drop the M3 altogether and let the three series be what it is, a small sedan, and let the new Z4 take over as the performance flagship since it's actually a sports car to begin with. I'm tired of manufacturers sacrificing ultimate performance in the name of hierarchal preservation. Case in point, Porsche Cayman.

  5. I hate when sick cars like this come out and performance numbers aren't provided. I mean, they even give mpg as if a person buying such a modified beast would actually give f*uck. Seriously - the car is $140k and the 1/4 mile, 0-60, top speed, track time (all which are the most relevant points of the swap arent they???) are mulled over for tire size, mileage and how much mpg you can expect. WOW... Phenomenal swap, but I lost interest almost as quickly as I gained it.
