Based on the BMW 3 Series (F30), the B3 is available in saloon and wagon body styles. The car was officially launched at the 2013 Geneva Motor Show. Development and introductionThe B3 is based on the BMW 335i and utilises a modified version of its N55 straight six engine. Alpina modified the engine by adding two smaller variable-geometry turbochargers in place of the standard single turbocharger, NGK spark plugs, electronically controlled bypass valve system, a high-performance fuel pump, a 40 percent larger intercooler, Alpina specific ECU along with a wiring loom and a forged high-strength steel crankshaft. These modifications allow the engine to generate {{cvt|410|PS|kW hp|0|abbr=on}} with RON 98 fuel and {{cvt|600|Nm|lbft|0|abbr=on}} of torque at 3,000 rpm. The front subframe along with the strut brace were modified in order to accommodate the powerful engine. The engine is mated to an 8-speed ZF "Touch tronic" automatic transmission with no manual transmission available as an option. The car is available in rear-wheel-drive and all-wheel-drive configurations. The transmission consists of three modes, "Automatic (D)", "Manual (M)" and "Sport (S)". The Automatic mode focuses on driving comfort while the Sport mode reduces shift time and throttle response. When combined with the "Sport" or "Sport +" driving modes of the Drive performance system, the gearshifts are quicker due to a reduction in torque caused by the interruption of the injection of fuel into a given cylinder for a fraction of a second. The B3 has an Akrapovič stainless steel exhaust system featuring quad exhaust pipes. The exhaust system has an electronically controlled valve that remains closed up to 2,500 rpm for more quiet city driving in comfort mode. In Sport mode however, the valve remains permanently open to provide optimum performance. The brakes used in the car have ventilated {{Convert|370|mm|in|1|abbr=on}} discs with 4-piston calipers at the front and ventilated {{Convert|345|mm|in|1|abbr=on}} discs with 2-piston calipers at the rear. The aluminium calipers feature Alpina lettering with classic Alpina Blue colour.[2] The suspension system is mostly based on the donor car but features adjustable dampers and Eibach springs which are 45 percent more stiffer. The system also features Alpina specific roll bars. The car has Michelin Pilot Sport tyres with 20-inch multi-spoke alloy wheels. The car also includes Alpina tuned Sports steering and an optional limited slip differential. The company claims a combined fuel economy of 37.2 mpg. The interior includes Alpina specific sports seats and BMW iDrive infotainment system as standard equipment with USB and Bluetooth connectivity. A Harman Kardon sound system, an in-car TV and a head-up display are optional. The company gives the customer a choice of five leather and veneer trims for the interior.[3] PerformanceThe B3 can accelerate from {{cvt|0-100|kph|mph|0|abbr=on}} in 4.2 seconds (4.3 seconds for the wagon version) and can attain a top speed of {{cvt|190|mph|kph|0|abbr=on|order=flip}} ({{cvt|188|mph|kph|0|abbr=on|order=flip}} for the wagon). The B3 can accelerate from {{cvt|30-70|mph|kph|0|abbr=on|order=flip}} in 4.2 seconds in third gear, 5.3 seconds in fourth gear and 7.3 seconds in fifth gear.[3] VariantsD3The D3 is the diesel powered variant of the B3. Unveiled at the 2013 Frankfurt Motor Show, the D3 is based on the 335d and utilises a modified version of its 3.0-litre N57 inline-6 engine. The engine has received the same modification as the B3, those being a larger intercooler, Alpina specific ECU and wiring loom and a high-strength steel crankshaft. These modifications allow the engine to generate {{cvt|350|PS|kW hp|0|abbr=on}} at 4,000 rpm and {{cvt|516|lbft|Nm|0|abbr=on|order=flip}} of torque. The engine is mated to the same 8-speed automatic transmission as found on the B3 with a limited slip differential available as an option. Like the B3, the D3 is available in either a saloon or a wagon body style. The engine delivers its peak torque from 1,500 rpm to 3,000 rpm and has a red-line of 4,800 rpm. The transmission features buttons for shifting gears mounted behind the steering column and has the same gear ratios as the donor car. The suspension system is the same as the B3 and features 40 percent stiffer springs as well as the wheels and tyres. The dampers are set to be softer in compression and firmer in rebound. The bushings and anti-rollbars are Alpina specific and the car's front sub-frame and strut-brace have been modified to accommodate the engine. There are four exterior colour choices available, those being Classic Alpina Green, Classic Alpina Blue, Sapphire Black and Mineral White with optional Alpina pinstripes. The D3 can be ordered with any option available on the standard 3 Series. Along with Alpina's own options of interior trim and leather upholstery. The D3 can accelerate from {{cvt|0-97|kph|mph|0|abbr=on}} in a claimed 4.6 seconds and can attain a claimed maximum speed of {{cvt|173|mph|kph|0|abbr=on|order=flip}}. The car has a claimed combined fuel economy of 53.3 mpg.[4] B3 SIntroduced at the 2017 Geneva Motor Show, the B3 S is the high performance variant of the B3. The 3.0-litre twin-turbocharged inline-6 engine found in the B3 is further modified to generate {{cvt|431|PS|kW hp|0|abbr=on}} and {{cvt|487|lbft|Nm|0|abbr=on|order=flip}} of torque. The transmission remains the same as in the standard B3 along with interior and exterior options.[5] Performance figures include a {{cvt|0-97|kph|mph|0|abbr=on}} acceleration time of 4.2 seconds (4.3 seconds for the wagon) and a top speed of {{cvt|306|kph|mph|0|abbr=on}}. Unlike the B3, the B3 S is based on the updated 335i.[6] References1. ^{{cite web|URL=https://f30.bimmerpost.com/forums/showthread.php?t=811899|title=Geneva 2013: Alpina B3 F30 Debuts with Full Specs|accessdate=1 November 2018}} 2. ^{{cite web|URL=https://paultan.org/2013/03/07/alpina-b3-biturbo/|title=Alpina B3 Bi-Turbo with 410 horsepower based on the F30|date=7 March 2013|accessdate=1 November 2018}} 3. ^1 {{cite web|URL=https://www.autocar.co.uk/car-review/alpina/b3-biturbo|title=Alpina B3 Bi-Turbo review|first=Matt|last=Prior|publisher=Autocar|accessdate=1 November 2018}} 4. ^{{cite web|URL=https://www.evo.co.uk/alpina/d3/7316/alpina-d3-biturbo-review-price-and-specs|title=Alpina D3 Biturbo review, price and specs|date=7 January 2014|first=Mike|last=Duff|publisher=EVO magazine|accessdate=1 November 2018}} 5. ^{{cite web|URL=https://www.roadandtrack.com/car-shows/geneva-auto-show/news/a32820/alpina-b3-s-b4-s/|title=The New Alpina B3 S Might Be the Best M3 Alternative|date=3 March 2017|first=Chris|last=Perkins|publisher=Road & Track|accessdate=1 November 2018}} 6. ^{{cite news|URL=https://www.drive.com.au/motor-news/2018-alpina-b3-s-and-b4-s-revealed-65384|title=2018 Alpina B3 S and B4 S revealed|accessdate=1 November 2018}} External links{{commonscat}} 8 : Alpina vehicles|Cars introduced in 2013|Cars introduced in 2017|Rear-wheel-drive vehicles|Sedans|Wagons|Compact executive cars|All-wheel-drive vehicles |
